Building my first rig with 6 GPUs using an Asus B250 MB, looking for advice

New member so please be gentle. I have been micro mining for a few months now (with my GTX 1060 and my new RTX 2080 ti) and want to step up my game a notch. I have my sites set on building the following system with the specs listed below so far. Any input on why I should not use a specific item or why I should use a certain item would be greatly appreciated!
1. Kingwin Bitcoin Miner Rig Case W/ 6, or 8 GPU Mining Stackable Frame x 1:
I have expansion in mind with this frame. It's stackable and ounces I ROI my first rig I plan on tossing a second level on to it. This frame is currently selling for around $50.

2. ROSEWILL Gaming 80 Plus Gold 1600W Power Supply (HERCULES-1600S) x 1:
The heart of any rig, the power! I like this one for it's 1600W and it's price. Currently running around $200.

3. ASUS B250 MINING EXPERT Motherboard x 1:
This motherboard is being used with expansion in mind. I want to start with 6 GPUs then build on that. Currently running around $140.

4. VOLADOR PCI-E Riser 1x to 16x Powered Riser Adapter Card (USB3) x 6:
Standard USB 3.0 risers. They come in a six-pack for about $20.

5. XFX Radeon RX 580 GTS XXX Edition (RX-580P8DFD6) x 6:
Currently cheaper than the Sapphire below. These are currently running around $170.
XFX Radeon RX 580 GTS XXX Edition (RX-580P8DFD6)

5-ALT. Sapphire Radeon Pulse RX 580 8GB (11265-05-20G) - BACKUP CHOICE GPU:
This is what I was looking at first then I found the cheaper XFX Radeon's above. These are currently running around $180.
Sapphire Radeon Pulse RX 580 8GB (11265-05-20G)

6. CPU:
Currently I do not have any CPUs in mind to use for this rig. I know I don't need a beefy CPU for running Windows. I plan on ONLY mining with GPUs in this rig. Suggestions are welcome!

7. Memory:
Currently I do not have any memory in my sites. Suggestions are welcome!

8. Harddrive:
I plan on using a simple 128GB USB thumb drive for the hard drive right now. Possibly something like an SSD if needed, but plan on using USB flash drive to start. Pros/Cons suggestions welcome!

I think I my video my endeavor and show everyone how fun/frustrating it all was. Catching all the pitfalls in hopes of helping others out etc. But first I need to have a plan and that's what this is. I need to do some lite research, get a good shopping list, make a payment plan, and an ROI schedule. Any feedback that the community could give me would be very helpful because I only know about 80% of what I need to know to build this rig. The 20% is the overclocking, bios issues (MB and gpu), and general knowledge of building a mining rig. I expect there to be pitfalls and parts I didn't think of until I start the build.

Is this the right time build a PC?

Or will there ever be a right time? Couple years ago I wanted to build a new pc and because of all the bitcoin mining rage gpu prices were outrageous. Now, once again I decided to build a pc again and I keep reading this is not a good time and should wait more for ryzen 4000, rtx 3000 etc. I feel like there is no end to waiting.

After doing some research I came up with something like this:
Ryzen 9 3900x processor
Gskill flare x 16 gb ram
Asus TUF X570 gaming mb
Evga 2070 Super gpu
1 tb Sabrent rocket nvme ssd and
this monitor https://www.newegg.com/p/N82E16824012012

My goal is 32" 1440p 144 hz gaming. I don't have a super strict budget but I don't want to spend too much money either. I know that 3900x and pci 4 ssd are overkill but since when that has stopped us? lol.
Does it make sense to buy this system now or once again I should keep waiting? I will also buy a ps5 when it comes out so I will mostly be playing wow, eve online, mmorpg and online games mostly.

I literally have tens of thousands of dollars in top-shelf hardware, looking to repurpose some before selling on eBay to build a NAS system, possibly a dedicated firewall device as well. o_O

Q1) What will you be doing with this PC? Be as specific as possible, and include specific games or programs you will be using.**

A1) This will be a dedicated NAS system for my home network. As such, I'm looking to have it:

- Host ##TB's of 720, 1080 & up resolution Movies and TV Shows I'm about to begin ripping from a MASSIVE DVD & Blueray collection I have.

- My kids are big on Minecraft. I understand it's possible to host your own "worlds" (or whatever they call the maps you can build) on your own "server". I think it would be pretty neat to offer them (& their friends - if can be done 'safely/securely') their own partition on one of my NAS HDD's.

- I also have accounts with a couple diff VPN companies... I understand it's possible (?) to sync said VPN's with a NAS, this might be a more relative topic on the next point/purpose...

- I'd like to be able to remotely link to this NAS for when I travel overseas and want to stream at my temp location from my house/this NAS.
______________________
Q2) What is your maximum budget before rebates/shipping/taxes?**

* A2) Here's where I make matters more complicated than most others would... I've been an advocate for Bitcoin and crypto-currencies in general since 2013. I invested in a small mining outfit back in 2014 (strictly Bitcoin/ASIC's). One of my buddies is the President of a large-scale mining operation (foreign and domestic) and he convinced me to dabble in the GPU mining-space. I made my first hardware purchase in Q4, 2017 and launched a small-scale GPU-Farm in my house since then. I had the rigs mining up until Q3 of 2018 (not cost-efficient to keep on, especially living in SoFlo) and since then, the hardware's been collecting dust (& pissing off my family members since they lost access to 3X rooms in the house - I won't let anyone go near my gear). One of my New Years Resolutions for 2019 was to clear out the house of all my mining equipment so that's all about to go up on eBay. So "budget" is relative to whatever I "MUST" spend if I can't repurpose any of the parts I already have on hand for this build... (Anyone having something I "need" and is looking to barter for one of the items I'll list later on in here, LMK).
______________________
Q3) When do you plan on building/buying the PC? Note: beyond a week or two from today means any build you receive will be out of date when you want to buy.**

A3) IMMEDIATELY! :)
______________________
Q4) What, exactly, do you need included in the budget? (ToweOS/monitokeyboard/mouse/etc\)**

A4) Well I had a half-assed idea approximately 1 year ago that it might be wise to build a bunch of 'gaming rigs' to sell on eBay with my intended repurposed mining hardware so I went on a shopping spree for like 6 months. That said; I've got a plethora of various other components that aren't even unboxed yet. 90% of the items I've purchased for this additional project were items that were marked down via MIR (mail-in-rebates) & what-not...
AFAIK, there are only 3X items I absolutely do not have which I 'MUST' find. Those would be - 1) Motherboard which accepts "ECC RAM". 2) CPU for said MOBO. 3) Said "ECC RAM".\* 
______________________
Q5) Which country (and state/province) will you be purchasing the parts in? If you're in US, do you have access to a Microcenter location?**

A5) I'm located in Southwest Florida. No Microcenter's here. Best Buy is pretty much my only option although I am a member of Newegg, Amazon & Costco if that makes any difference?
______________________
Q6) If reusing any parts (including monitor(s)/keyboard/mouse/etc), what parts will you be reusing? Brands and models are appreciated.**

A6) In an attempt to better clean up this Q&A, I'm going to list the items I have on-hand at the end of this questionnaire in-case passers-by feel like this might be a TLDR.* (Scroll to the bottom & you'll see what I mean).
______________________
Q7) Will you be overclocking? If yes, are you interested in overclocking right away, or down the line? CPU and/or GPU?**

A7) I don't think that's necessary for my intended purpose although - I'm not against it if that helps & FWIW, I'm pretty skilled @ this task already (it's not rocket science).
______________________
Q8) Are there any specific features or items you want/need in the build? (ex: SSD, large amount of storage or a RAID setup, CUDA or OpenCL support, etc)**

A8) As stated in A4; ECC RAM is non-negotiable... RAID seems like a logical application here as well.

- This will predominantly be receiving commands from MacOS computers. I don't think that matters really but figured it couldn't hurt to let you guys know.\*

- I'd also be quite fond of implementing "PFSENSE" (or something of that caliber) applied to this system so I could give my Netgear Nighthawks less stress in that arena, plus my limited understanding of PFSENSE is that it's ability to act as a firewall runs circles around anything that comes with consumer-grade Wi-Fi routers (like my Nighthawks). Just the same, I'm open to building a second rig just for the firewall.\*

- Another desirable feature would be that it draws as little electricity from the wall as possible. (I'm EXTREMELY skilled in this arena. I have "Kill-A-Watts" to test/gauge on, as well as an intimate understanding of the differences between Silver, Gold, Platinum and Titanium rated PSU's. As well as having already measured each of the PSU's I have on-hand and taken note of the 'target TDP draw' ("Peak Power Efficiency Draw") each one offers when primed with X amount of GPU's when I used them for their original purpose.\*

- Last, but not least, sound (as in noise created from the rig). I'd like to prop this device up on my entertainment center in the living room. I've (almost) all of the top-shelf consumer grade products one could dream of regarding fans and other thermal-related artifacts.

- Almost forgot; this will be hosting to devices on the KODI platform (unless you guys have better alternative suggestions?)
______________________
Q9) Do you have any specific case preferences (Size like ITX/microATX/mid-towefull-tower, styles, colors, window or not, LED lighting, etc), or a particular color theme preference for the components?**

A9) Definitely! Desired theme would be WHITE. If that doesn't work for whatever reason, black or gray would suffice. Regarding "Case Size". Nah, that's not too important although I don't foresee a mini-ITX build making sense if I'm going to be cramming double digit amounts of TB in the system, Internal HDD's sounds better than a bunch of externals plugged in all the USB ports.
______________________
Q10) Do you need a copy of Windows included in the budget? If you do need one included, do you have a preference?**

A10) I don't know. If I do need a copy of Windows, I don't have one so that's something I'll have to consider I guess. I doubt that's a necessity though.

Needless to say, I have at least 1X of everything mentioned above. In most all cases, I have multiples of these items but obviously won't be needing 2X CPU's, Cases, etc...

Naturally, I have GPU's. Specifically;

At least 1X of every. Single. NVIDIA GTX 1070 TI (Yes, I have every variation of the 1070 ti made by MSI, EVGA and Zotac. The only brand I don't have is the Gigabyte line. My partners have terrible experience with those so I didn't even bother. I'm clearly not going to be needing a GPU for this build but again, I'm cool with discussing the idea of a barter if anyone reading this is in the market for one.

I also have some GTX 1080 TI's but those are already spoken for, sorry.

It's my understanding that select CPU's I have on this list are ECC Friendly and AFAIK, only 1 of my MOBO's claims to be ECC Friendly (The ASROCK AB350M PRO4), but for the life of me, I can't find any corresponding forums that confirm this and/or direct me to a listing where I can buy compatible RAM. Just the same, if I go w/ the ASROCK MOBO, that means I'd be using one of the Ryzens. Those are DEF. power hungry little buggers. Not a deal-breaker, just hoping to find something a little more conservative in terms of TDP.


In closing, I don't really need someone to hold my hand with the build part as much as figuring out which motherboard, CPU and RAM to get. Then I'm DEFINITELY going to need some guidance on what OS is best for my desired purpose. If building 2X Rigs makes sense, I'm totally open to that as well...
Rig 1 = EPIC NAS SYSTEM
Rig 2 = EPIC PFSENSE (or the like) DEDICATED FIREWALL

Oh, I almost forgot... The current routers I'm using are...
1X Netgear Nighthawk 6900P (Modem + Router)
1X Netgear Nighthawk X6S (AC 4000 I believe - Router dedicated towards my personal devices - no IoT &/or Guests allowed on this one)
1X TP-Link Archer C5 (Router). Total overkill after implementing the Nighthawks but this old beast somehow has the best range, plus it has 2X USB ports so for now, it's dedicated towards my IoT devices.
---- I also have a few other Wi-Fi routers (Apple Airport Extreme & some inferior Netgear's but I can only allocate so many WiFi Routers to so many WiFi channels w/out pissing off my neighbors) On that note, I have managed to convince my neighbors to let me in their house/WiFi configuration so we all have our hardware locked on specific, non-competing frequencies/channels so everyone's happy. :)


Please spare me the insults as I insulted myself throughout this entire venture. Part of why I did this was because when I was a kid, I used to fantasize about building a 'DREAM PC' but could never afford such. To compensate for this deficiency, I would actually print out the latest and greatest hardware components on a word document, print the lists up & tape to wall (for motivation). I was C++ certified at the age of 14 and built my first PC when I was 7. At the age of 15 I abandoned all hope in the sector and moved on to other aspirations. This entire ordeal was largely based off me finally fulfilling a childhood fantasy. On that note = mission accomplished. Now if I'm actually able to fulfill my desires on this post, I'm definitely going to feel less shitty about blowing so much money on all this stuff over the last couple years.

TIA for assisting in any way possible. Gotta love the internets!


THE END.

EDIT/UPDATE (5 hours after OP) - My inbox is being inundated with various people asking for prices and other reasonable questions about my hardware being up for sale. Not to be redundant but rather to expound on my previous remarks about 'being interested in a bartetrade' with any of you here...

I did say I was going to sell my gear on eBay in the near future, I also said I wanted to trade/barter for anything relative to helping me accomplish my OP's mission(s). I'm not desperate for the $$$ but I'm also not one of those people that likes to rip other people off. That said; I value my time and money invested in this hardware and I'm only willing to unload it all once I've established I have ZERO need for any of it here in my home first. Hence my writing this lengthy thread in an attempt to repurpose at least a grand or two I've already spent.

One of the most commonly asked questions I anticipate receiving from interested bodies is going to be "How hard were you on your hardware?" Contrary to what anyone else would have probably done in my scenario which is say they were light on it whether they were or weren't, I documented my handling of the hardware, and have no problem sharing such documentation with verified, interested buyers (WHEN THE TIME COMES) to offer you guys peace of mind.

I have photo's and video's of the venture from A-Z. I am also obliged to provide (redacted) electricity bill statements where you can correlate my photo's (power draw on each rig), and also accurately deduct the excess power my house consumed with our other household appliances. Even taking into consideration how much (more) I spent in electricity from keeping my house at a constant, cool 70-72F year-round (via my Nest thermostat). Even without the rigs, I keep my AC @ 70 when I'm home and for the last 1.5-2 years, I just so happened to spend 85% of my time here at my house. When I would travel, I'd keep it at 72 for my wife & kids.
Additionally; I had each GPU 'custom' oveunderclocke'd (MSI Afterburner for all GPU's but the EVGA's).*
I doubt everyone reading this is aware so this is for those that don't.... EVGA had the brilliant idea of implementing what they call "ICX technology" in their latest NVIDIA GTX GPU's. The short(est) explanation of this "feature" goes as follows:

EVGA GPU's w/ "ICX 9 & above" have EXTRA HEAT/THERMAL SENSORS. Unlike every other GTX 1070 ti on the market, the one's with this feature actually have each of 2/2 on-board fans connected to individual thermal sensors. Which means - if you were to use the MSI Afterburner program on one of these EVGA's and create a custom fan curve for it, you'd only be able to get 1/2 of the fans to function the way intended. The other fan simply would not engage as the MSI Afterburner software wasn't designed/coded to recognize/ communicate with an added sensor (let alone sensor'S). This, in-turn, would likely result in whoever's using it the unintended way having a GPU defect on them within the first few months I'd imagine... Perhaps if they had the TDP power settings dumbed down as much as I did (60-63%), they might get a year or two out of it since it wouldn't run as near as hot, but I doubt any longer than that since cutting off 50% of the cooling system on one of these can't be ignored too long, surely capacitors would start to blow and who knows what else...
(Warning = RANT) Another interesting side-note about the EVGA's and their "Precision-X" OveUnderclocking software is that it's designed to only recognize 4X GPU's on a single system. For miners, that's just not cool. My favorite builds had 8X and for the motherboards that weren't capable of maintaining stable sessions on 8, I set up with 6X. Only my EVGA Rigs had 3 or 4X GPU's dedicated to a single motherboard. Furthermore, and as stated in an earlier paragraph, (& this is just my opinion) = EVGA SOFTWARE SUCKS! Precision X wasn't friendly with every motherboard/CPU I threw at it and their extension software for the CLC Close-Loop-Cooling/ CPU water-coolers simply didn't work on anything, even integrating into their own Precision-X software. The amount of time it took me to finally find compatible matches with that stuff was beyond maddening. (END RANT).
Which leads me to my other comments on the matter. That's what I had every single 1070 ti set at for TDP = 60-63%. Dropping the power load that much allowed me to bring down (on average) each 1070 ti to a constant 110-115W (mind you, this is only possible w/ "Titanium" rated PSU's, Platinum comes pretty damn close to the Titanium though) while mining Ethereum and was still able to maintain a bottom of 30 MH/s and a ceiling of 32 MH/s. Increasing the TDP to 80, 90, 100% or more only increased my hashrates (yields) negligibly, like 35-36 MH/s TOPS, which also meant each one was not only pulling 160-180W+ (Vs. the aforementioned 115'ish range), it also meant my rigs were creating a significantly greater amount of heat! Fortunately for the GPU's and my own personal habits, I live in South Florida where it's hot as balls typically, last winter was nothing like this one. Increasing my yields by 10-15% didn't justify increasing the heat production in my house by >30%, nor the added electricity costs from subjecting my AC handlers to that much of an extra work-load. For anyone reading this that doesn't know/understand what I'm talking about - after spending no less than 2-3 hours with each. and. every. one. I didn't play with the settings on just one and universally apply the settings to the rest. I found the 'prime' settings and documented them with a label-maker and notepad. Here's the math in a more transparent manner:

*** I NEVER LET MY GPU's BREACH 61C, EVER. Only my 8X GPU rigs saw 60-61 & it was the ones I had in the center of the build (naturally). I have REALLY high power fans (used on BTC ASIC MINERS) that were sucking air from those GPU's which was the only way I was able to obtain such stellar results while mining with them. **\*
Mining at "acceptable" heat temps (not acceptable to me, but most of the internet would disagree = 70C) and overclocking accordingly brings in X amount of yields per unit. =
'Tweaking' (underclocking) the GPU's to my parameters reduced my yield per unit from -10-15%, but it SAVED me well over 30-35% in direct electricity consumption, and an unknown amount of passive electricity consumption via creating approximately 20%+ less heat for my AC handler to combat.

I say all this extra stuff not just for anyone interested in mining with their GPU's, but really to answer (in-depth) the apparent questions you people are asking me in PM's. Something else that should help justify my claims of being so conservative should be the fact I only have/used "Platinum and Titanium" rated PSU's. Heat production, power efficiency and longevity of the hardware were ALWAYS my top priority.* . I truly thought Crypto would continue to gain and/or recover and bounce back faster than it did. If this project had maintained positive income for 12 months+, I'd have expanded one of our sites to also cater to GPU mining on a gnarly scale.

Once I have my NAS (& possibly 2nd rig for the firewall) successfully built, I'll be willing/able to entertain selling you guys some/all of the remaining hardware prior to launching on eBay. If there's something you're specifically looking for that I listed having, feel free to PM me with that/those specific item(s). Don't count on an immediate response but what you can count on is me honoring my word in offering whoever asks first right of refusal when the time comes for me to sell this stuff. Fortunately for me, PM's are time-stamped so that's how I'll gauge everyone's place in line. I hope this extra edit answers most of the questions you guys wanted to have answered and if not, sorry I guess. I'll do my best to bring light to anything I've missed out on after I realize whatever that error was/is. The only way anyone is getting first dibs on my hardware otherwise is if they either offer compelling insight into my original questions, or have something I need to trade w/.

THE END (Round#2)

Satoshi birthday 7 million quiz

To celebrate Satoshi's birthday I am giving away a brain wallet with some satoshis on it. Not much, only 7 million, which is about $350 now. This is just for fun and to experiment with this format. Maybe help people learn about brain wallets.
I have just sent the satoshis to the first address in the brain wallet.
To find the seed, answer the following 7 quiz questions (multiple choice). The SHA 256 hash of all correct answers combined is the wallet seed. Insert one space between answers.
Brute forcing all 16384 possible combinations is a trivial exercise if you are prepared for this kind of quiz and have hours or days of time at your disposal. I count on that not being the case and the race getting decided by who gets the perfect answer first by either knowing the answer or searching faster than others. From that point on it still takes some time to derive and sweep the relevant private key from the brain wallet seed. And of course you need to know how to do that in the first place. If multiple perfect scoring answers compete in that race, it may be a matter of luck which sweeping transaction confirms first.
Let's see how long it takes before someone sweeps that address. It will be interesting to see if it takes more or less than the average ten minutes for finding a block.
  1. On December 7, 2010 a) There was a guy describing himself as an ordained priest offering to "bless your dildo" for only one bitcoin on the Bitcoin subreddit. b) Satoshi was a moderator of the Bitcoin subreddit with the user name noagendamarker. c) The Bitcoin subreddit had less subscribers than Satoshi's age at the time. d) There were were only two posts about price on the Bitcoin subreddit.
  2. Satoshi chose April 5 as his birthday because the American government prohibited private holding of gold on that day. Which of the following is correct? a) The government paid less than the world market price for gold when they prohibited private holding that day. b) Roosevelt had the authority to do this under the Trading with the Enemy Act of 1917 and the executive order also prohibited importing gold into the United States. c) Franklin D. Roosevelt required all American citizens by executive order 6102 to deliver all of their gold at the fixed price of $20.67 before May 1st. d) In a challenge to this executive order the government won by a 6 to 3 majority decision at the Supreme Court.
  3. If you mined bitcoins on Satoshi's 34th birthday, you would on average mine (according to a post by Satoshi) a) A few tens of bitcoins a day. b) A few bitcoins a day. c) A few thousand bitcoins a day. d) A few hundred bitcoins a day.
  4. Which of the following Bitcoin burn addresses has the largest balance? a) 1AndrewYangForPresident2o2ozm6Pzd. b) 1WarrenForPresident2o2oxxxy3DCZMZ. c) 1SandersForPresident2o2oxxxvYnPyW. d) 1TRUMPforPresident2o2oxxxxxAvY6s.
  5. The author of a paper proposing a practical escrow cash system in 1996 was a) Satoshi Sakamoto. b) Tatsuaki Okamoto. c) Satoshi Nakamoto. d) Tatsuaki Nakamura.
  6. The small girl looking at the two most famous pizzas in history in 2010 was a) wearing a red t-shirt. b) wearing a green t-shirt. c) wearing a blue t-shirt. d) wearing a yellow t-shirt.
  7. RPOW was a proof-of-work based system using trusted computing. It ran on a) an IBM 4758 PCI Cryptographic Coprocessor. b) an Intel 4758 PCI Cryptographic Coprocessor. c) an AMD 4758 PCI Cryptographic Coprocessor. d) a Dell 4758 PCI Cryptographic Coprocessor.

[META] New to PC Building? - September 2018 Edition

Intro

You've heard from all your gaming friends/family or co-workers that custom PCs are the way to go. Or maybe you've been fed up with your HP, Dell, Acer, Gateway, Lenovo, etc. pre-builts or Macs and want some more quality and value in your next PC purchase. Or maybe you haven't built a PC in a long time and want to get back into the game. Well, here's a good place to start.

Instructions

  1. Make a budget for your PC (e.g., $800, $1000, $1250, $1500, etc.).
  2. Decide what you will use your PC for.
    • For gaming, decide what games and at what resolution and FPS you want to play at.
    • For productivity, decide what software you'll need and find the recommended specs to use those apps.
    • For a bit of both, your PC build should be built on the HIGHEST specs recommended for your applications (e.g., if you only play FortNite and need CPU power for CFD simulations, use specs recommended for CFD).
    Here are some rough estimates for builds with entirely NEW parts:
    1080p 60FPS ultra-settings modern AAA gaming: ~$1,200
    1440p 60FPS high/ultra-settings modern AAA gaming: ~$1,600
    1080p 144FPS ultra-settings modern AAA gaming: $2,000
    4K 50FPS medium/high-settings modern AAA gaming: > $2,400
    It's noted that some compromises (e.g., lower settings and/or resolution) can be made to achieve the same or slightly lower gaming experience within ±15% of the above prices. It's also noted that you can still get higher FPS on older or used PCs by lowering settings and/or resolution AND/OR buying new/used parts to upgrade your system. Make a new topic about it if you're interested.
    Also note that AAA gaming is different from e-sport games like CSGO, DOTA2, FortNite, HOTS, LoL, Overwatch, R6S, etc. Those games have lower requirements and can make do with smaller budgets.
  3. Revise your budget AND/OR resolution and FPS until both are compatible. Compare this to the recommended requirements of the most demanding game on your list. For older games, you might be able to lower your budget. For others, you might have to increase your budget.
    It helps to watch gaming benchmarks on Youtube. A good example of what you're looking for is something like this (https://www.youtube.com/watch?v=9eLxSOoSdjY). Take note of the resolution, settings, FPS, and the specs in the video title/description; ask yourself if the better gaming experience is worth increasing your budget OR if you're okay with lower settings and lowering your budget. Note that you won't be able to see FPS higher than 60FPS for Youtube videos; something like this would have to be seen in-person at a computer shop.
  4. Make a build on https://ca.pcpartpicker.com/. If you still have no idea how to put together parts, start here (http://www.logicalincrements.com/) to get an understanding of PC part tiers. If you want more info about part explanations and brief buying tips, see the next section below.
  5. Click on the Reddit logo button next to Markup, copy and paste the generated text (in markup mode if using new Reddit), and share your build for review!
  6. Consider which retailer to buy your parts from. Here's a table comparing different retailers: https://docs.google.com/spreadsheets/d/1L8uijxuoJH4mjKCjwkJbCrKprCiU8CtM15mvOXxzV1s/edit?usp=sharing
  7. Buy your parts! Use PCPP above to send you e-mail alerts on price drops or subscribe to /bapcsalescanada for deals.
    You can get parts from the following PC retailers in alphabetical order:
  8. After procuring your parts, it's time to build. Use a good Youtube tutorial like this (https://www.youtube.com/watch?v=IhX0fOUYd8Q) that teach BAPC fundamentals, but always refer to your product manuals or other Youtube tutorials for part-specific instructions like CPU mounting, radiator mounting, CMOS resetting, etc. If it everything still seems overwhelming, you can always pay a computer shop or a friend/family member to build it for you.
    It might also be smart to look up some first-time building mistakes to avoid:
  9. Share your experience with us.
  10. If you have any other questions, use the search bar first. If it's not there, make a topic.

BAPC News (Last Updated - 2018/09/20)

CPU

https://www.tomshardware.com/news/intel-9000-series-cpu-faq,37743.html
Intel 9000 CPUs (Coffee Lake Refresh) will be coming out in Q4. With the exception of i9 (8-core, 12 threads) flagship CPUs, the i3, i5, and i7 lineups are almost identical to their Intel 8000 (Coffee Lake) series, but slightly clocked faster. If you are wondering if you should upgrade to the newer CPU on the same tier (e.g., i5-8400 to i5-9400), I don't recommend that you do as you will only see marginal performance increases.

Mobo

https://www.anandtech.com/show/13135/more-details-on-intels-z390-chipset-exposed
Z370s will now be phased out for Z390s boards, which will natively support Intel 9000 CPUs (preferably i5-9600K, i7-9700K, and i9-9900K).

GPU

https://www.youtube.com/watch?v=WDrpsv0QIR0
RTX 2080 and 2080 Ti benchmarks are out; they provide ~10 and ~20 frames better than the 1080 Ti and also feature ray tracing (superior lighting and shadow effects) which is featured in only ~30 games so far (i.e., not supported a lot); effectively, they provide +25% more performance for +70% increased cost. My recommendation is NOT to buy them unless you need it for work or have lots of disposable income. GTX 1000 Pascal series are still relevant in today's gaming specs.

Part Explanations

CPU

The calculator part. More GHz is analogous to fast fingers number crunching in the calculator. More cores is analogous to having more calculators. More threads is analogous to having more filing clerks piling more work for the calculator to do. Microarchitectures (core design) is analogous to how the internal circuit inside the calculator is designed (e.g., AMD FX series are slower than Intel equivalents even with higher OC'd GHz speeds because the core design is subpar). All three are important in determining CPU speed.
In general, higher GHz is more important for gaming now whereas # cores and threads are more important for multitasking like streaming, video editing, and advanced scientific/engineering computations. Core designs from both AMD and Intel in their most recent products are very good now, but something to keep in mind.

Overclocking

The basic concept of overclocking (OCing) is to feed your CPU more power through voltage and hoping it does calculations faster. Whether your parts are good overclockers depends on the manufacturing process of your specific part and slight variations in materials and manufacturing process will result in different overclocking capability ("silicon lottery"). The downside to this is that you can void your warranties because doing this will produce excess heat that will decrease the lifespan of your parts AND that there is a trial-and-error process to finding OC settings that are stable. Unstable OC settings result in computer freezes or random shut-offs from excess heat. OCing will give you extra performance often for free or by investing in a CPU cooler to control your temperatures so that the excess heat will not decrease your parts' lifespans as much. If you don't know how to OC, don't do it.

Current Products

Intel CPUs have higher GHz than AMD CPUs, which make them better for gaming purposes. However, AMD Ryzen CPUs have more cores and threads than their Intel equivalents. The new parts are AMD Ryzen 3, 5, or 7 2000 series or Intel i3, i5, or i7 8000 series (Coffee Lake). Everything else is outdated.
If you want to overclock on an AMD system, know that you can get some moderate OC on a B350/B450 with all CPUs. X370/X470 mobos usually come with better VRMs meant for OCing 2600X, 2700, and 2700X. If you don't know how to OC, know that the -X AMD CPUs have the ability to OC themselves automatically without manually settings. For Intel systems, you cannot OC unless the CPU is an unlocked -K chip (e.g., i3-8350K, i5-8600K, i7-8700K, etc.) AND the motherboard is a Z370 mobo. In general, it is not worth getting a Z370 mobo UNLESS you are getting an i5-8600K and i7-8700K.

CPU and Mobo Compatibility

Note about Ryzen 2000 CPUs on B350 mobos: yes, you CAN pair them up since they use the same socket. You might get an error message on PCPP that says that they might not be compatible. Call the retailer and ask if the mobo you're planning on buying has a "Ryzen 2000 Series Ready" sticker on the box. This SHOULD NOT be a problem with any mobos manufactured after February 2018.
Note about Intel 9000 CPUs on B360 / Z370 mobos: same as above with Ryzen 2000 CPUs on B350 or X370 boards.

CPU Cooler (Air / Liquid)

Air or liquid cooling for your CPU. This is mostly optional unless heavy OCing on AMD Ryzen CPUs and/or on Intel -K and i7-8700 CPUs.
For more information about air and liquid cooling comparisons, see here:

Motherboard/mobo

Part that lets all the parts talk to each other. Comes in different sizes from small to big: mITX, mATX, ATX, and eATX. For most people, mATX is cost-effective and does the job perfectly. If you need more features like extra USB slots, go for an ATX. mITX is for those who want a really small form factor and are willing to pay a premium for it. eATX mobos are like ATX mobos except that they have more features and are bigger - meant for super PC enthusiasts who need the features.
If you are NOT OCing, pick whatever is cheap and meets your specs. I recommend ASUS or MSI because they have RMA centres in Canada in case it breaks whereas other parts are outside of Canada like in the US. If you are OCing, then you need to look at the quality of the VRMs because those will greatly influence the stability and lifespan of your parts.

Memory/RAM

Part that keeps Windows and your software active. Currently runs on the DDR4 platform for new builds. Go for dual channel whenever possible. Here's a breakdown of how much RAM you need:
AMD Ryzen CPUs get extra FPS for faster RAM speeds (ideally 3200MHz) in gaming when paired with powerful video cards like the GTX 1070. Intel Coffee Lake CPUs use up a max of 2667MHz for B360 mobos. Higher end Z370 mobos can support 4000 - 4333MHz RAM depending on the mobo, so make sure you shop carefully!
It's noted that RAM prices are highly inflated because of the smartphone industry and possibly artificial supply shortages. For more information: https://www.extremetech.com/computing/263031-ram-prices-roof-stuck-way

Storage

Part that store your files in the form of SSDs and HDDs.

Solid State Drives (SSDs)

SSDs are incredibly quick, but are expensive per TB; they are good for booting up Windows and for reducing loading times for gaming. For an old OEM pre-built, upgrading the PC with an SSD is the single greatest speed booster you can do to your system. For most people, you want to make sure the SSD you get is NOT DRAM-less as these SSDs do not last as long as their DRAM counterparts (https://www.youtube.com/watch?v=ybIXsrLCgdM). It is also noted that the bigger the capacity of the SSD, the faster they are. SSDs come in four forms:
The 2.5" SATA form is cheaper, but it is the old format with speeds up to 550MB/s. M.2 SATA SSDs have the same transfer speeds as 2.5" SATA SSDs since they use the SATA interface, but connect directly to the mobo without a cable. It's better for cable management to get an M.2 SATA SSD over a 2.5" SATA III SSD. M.2 PCI-e SSDs are the newest SSD format and transfer up to 4GB/s depending on the PCI-e lanes they use (e.g., 1x, 2x, 4x, etc.). They're great for moving large files (e.g., 4K video production). For more info about U.2 drives, see this post (https://www.reddit.com/bapccanada/comments/8jxfqs/meta_new_to_pc_building_may_2018_edition/dzqj5ks/). Currently more common for enterprise builds, but could see some usage in consumer builds.

Hard Disk Drives (HDDs)

HDDs are slow with transfer speeds of ~100MB/s, but are cheap per TB compared to SSDs. We are now at SATA III speeds, which have a max theoretical transfer rate of 600MB/s. They also come in 5400RPM and 7200RPM forms. 5400RPM uses slightly less power and are cheaper, but aren't as fast at dealing with a large number of small files as 7200RPM HDDs. When dealing with a small number of large files, they have roughly equivalent performance. It is noted that even a 10,000RPM HDD will still be slower than an average 2.5" SATA III SSD.

Others

SSHDs are hybrids of SSDs and HDDs. Although they seem like a good combination, it's much better in all cases to get a dedicated SSD and a dedicated HDD instead. This is because the $/speed better for SSDs and the $/TB is better for HDDs. The same can be said for Intel Optane. They both have their uses, but for most users, aren't worth it.

Overall

I recommend a 2.5" or M.2 SATA ≥ 250GB DRAM SSD and a 1TB or 2TB 7200RPM HDD configuration for most users for a balance of speed and storage capacity.

Video Card/GPU

Part that runs complex calculations in games and outputs to your monitor and is usually the most expensive part of the budget. The GPU you pick is dictated by the gaming resolution and FPS you want to play at.
In general, all video cards of the same product name have almost the same non-OC'd performance (e.g., Asus Dual-GTX1060-06G has the same performance as the EVGA 06G-P4-6163-KR SC GAMING). The different sizes and # fans DO affect GPU OCing capability, however. The most important thing here is to get an open-air video card, NOT a blower video card (https://www.youtube.com/watch?v=0domMRFG1Rw). The blower card is meant for upgrading pre-builts where case airflow is limited.
For cost-performance, go for the NVIDIA GTX cards because of the cryptomining industry that has inflated AMD RX cards. Bitcoin has taken a -20% hit since January's $10,000+ as of recently, but the cryptomining industry is still ongoing. Luckily, this means prices have nearly corrected itself to original MSRP in 2016.
In general:
Note that if your monitor has FreeSync technology, get an AMD card. If your monitor has G-Sync, get a NVIDIA card. Both technologies allow for smooth FPS gameplay. If you don't have either, it doesn't really matter which brand you get.

New NVIDIA GeForce RTX Series

New NVIDIA 2000 RTX series have been recently announced and will be carried in stores in Q3 and Q4. Until all of the products have been fully vetted and reviewed, we cannot recommend those yet as I cannot say if they are worth what NVIDIA has marketed them as. But they will be faster than their previous equivalents and will require more wattage to use. The 2070, 2080, and 2080 Ti will feature ray tracing, which is a new feature seen in modern CG movies that greatly enhances lighting and shadow effects. At this time, < 30 games will use ray tracing (https://www.pcgamer.com/21-games-will-support-nvidias-real-time-ray-tracing-here-are-demos-of-tomb-raider-and-control/). It's also noted that the 2080 Ti is the Titan XP equivalent, which is why it's so expensive. (https://www.youtube.com/watch?v=Irs8jyEmmPQ) The community's general recommendation is NOT to pre-order them until we see some reviews and benchmarks from reviewers first.
Looks like a couple of benchmarks are out. While keeping other parts equal the following results were obtained(https://videocardz.com/77983/nvidia-geforce-rtx-2080-ti-and-rtx-2080-official-performance-unveiled). So the 2080 and 2080 Ti are better than last generation's 1080 Ti by ~10 and ~20 frames respectively.

Case

Part that houses your parts and protects them from its environment. Should often be the last part you choose because the selection is big enough to be compatible with any build you choose as long as the case is equal to or bigger than the mobo form factor.
Things to consider: aesthetics, case airflow, cable management, material, cooling options (radiators or # of fan spaces), # fans included, # drive bays, toolless installation, power supply shroud, GPU clearance length, window if applicable (e.g., acrylic, tempered glass), etc.
It is recommended to watch or read case reviews on Youtube to get an idea of a case's performance in your setup.

Power Supply/PSU

Part that runs your PC from the wall socket. Never go with an non-reputable/cheap brand out on these parts as low-quality parts could damage your other parts. Recommended branded PSUs are Corsair, EVGA, Seasonic, and Thermaltake, generally. For a tier list, see here (https://linustechtips.com/main/topic/631048-psu-tier-list-updated/).

Wattage

Wattage depends on the video card chosen, if you plan to OC, and/or if you plan to upgrade to a more powerful PSU in the future. Here's a rule of thumb for non-OC wattages that meet NVIDIA's recommendations:
There are also PSU wattage calculators that you can use to estimate your wattage. How much wattage you used is based on your PC parts, how much OCing you're doing, your peripherals (e.g., gaming mouse and keyboard), and how long you plan to leave your computer running, etc. It is noted that these calculators use conservative estimates, so use the outputted wattage as a baseline of how much you need. Here are the calculators (thanks, VitaminDeity).
Pick ONE calculator to use and use the recommended wattage, NOT recommended product, as a baseline of what wattage you need for your build. Note that Cooler Master and Seasonic use the exact calculator as Outervision. For more details about wattage, here are some reference videos:

Modularity

You might also see some info about modularity (non-modular, semi-modular, or fully-modular). These describe if the cables will come connected to the PSU or can be separated of your own choosing. Non-modular PSUs have ALL of the cable connections attached to the PSU with no option to remove unneeded cables. Semi-modular PSUs have separate cables for HDDs/SSDs and PCI-e connectors, but will have CPU and mobo cables attached. Modular PSUs have all of their cables separate from each other, allowing you to fully control over cable management. It is noted that with decent cooling and airflow in your case, cable management has little effect on your temperatures (https://www.youtube.com/watch?v=YDCMMf-_ASE).

80+ Efficiency Ratings

As for ratings (80+, 80+ bronze, 80+ gold, 80+ platinum), these are the efficiencies of your PSU. Please see here for more information. If you look purely on electricity costs, the 80+ gold PSUs will be more expensive than 80+ bronze PSUs for the average Canadian user until a breakeven point of 6 years (assuming 8 hours/day usage), but often the better performance, longer warranty periods, durable build quality, and extra features like fanless cooling is worth the extra premium. In general, the rule of thumb is 80+ bronze for entry-level office PCs and 80+ gold for mid-tier or higher gaming/workstation builds. If the price difference between a 80+ bronze PSU and 80+ gold PSU is < 20%, get the 80+ gold PSU!

Warranties

Warranties should also be looked at when shopping for PSUs. In general, longer warranties also have better PSU build quality. In general, for 80+ bronze and gold PSU units from reputable brands:
Any discrepancies are based on varied wattages (i.e., higher wattages have longer warranties) or updated warranty periods. Please refer to the specific product's warranty page for the correct information. For EVGA PSUs, see here (https://www.evga.com/support/warranty/power-supplies/). For Seasonic PSUs, see here (https://seasonic.com/support#period). For Corsair PSUs, see here (https://www.corsair.com/ca/en/warranty).
For all other PSU inquiries, look up the following review sites for the PSUs you're interested in buying:
These guys are engineering experts who take apart PSUs, analyze the quality of each product, and provide an evaluation of the product. Another great website is http://www.orionpsudb.com/, which shows which PSUs are manufactured by different OEMs.

Operating System (OS)

Windows 10

The most common OS. You can download the ISO here (https://www.microsoft.com/en-ca/software-download/windows10). For instructions on how to install the ISO from a USB drive, see here (https://docs.microsoft.com/en-us/windows-hardware/manufacture/desktop/install-windows-from-a-usb-flash-drive) or watch a video here (https://www.youtube.com/watch?v=gLfnuE1unS8). For most users, go with the 64-bit version.
If you purchase a Windows 10 retail key (i.e., you buy it from a retailer or from Microsoft directly), keep in mind that you are able to transfer it between builds. So if you're building another PC for the 2nd, 3rd, etc. time, you can reuse the key for those builds PROVIDED that you deactivate your key before installing it on your new PC. These keys are ~$120.
However, if you have an OEM key (e.g., pre-builts), that key is tied specifically to your mobo. If you ever decide to upgrade your mobo on that pre-built PC, you might have to buy a new Windows 10 license. For more information, see this post (https://www.techadvisor.co.uk/feature/windows/windows-10-oem-or-retail-3665849/). The cheaper Windows 10 keys you can find on Kinguin are OEM keys; activating and deactivating these keys may require phoning an automated Microsoft activation line. Most of these keys are legitimate and cost ~$35, although Microsoft does not intend for home users to obtain this version of it. Buyer beware.
The last type of key is a volume licensing key. They are licensed in large volumes to corporate or commercial usage. You can find lots of these keys on eBay for ~$10, but if the IT department who manages these keys audit who is using these keys or if the number of activations have exceeded the number allotted on that one key, Microsoft could block that key and invalidate your license. Buyer beware.
For more information on differentiating between all three types of keys, see this page (https://www.tenforums.com/tutorials/49586-determine-if-windows-license-type-oem-retail-volume.html).
If money is tight, you can get Windows 10 from Microsoft and use a trial version of it indefinitely. However, there will be a watermark in the bottom-right of your screen until you activate your Windows key.

MacOS

If you're interested in using MacOS, look into Hackintosh builds. This will allow you to run MacOS to run on PC parts, saving you lots of money. These builds are pretty picky about part compatibility, so you might run into some headaches trying to go through with this. For more information, see the following links:

Linux

If you're interested in a free open-source OS, see the following links:
For more information, go to /linux, /linuxquestions, and /linux4noobs.

Peripherals

Monitors

Keyboards and Mice

Overall

Please note that the cost-performance builds will change daily because PC part prices change often! Some builds will have excellent cost-performance one day and then have terrible cost-performance the next. If you want to optimize cost-performance, it is your responsibility to do this if you go down this route!
Also, DO NOT PM me with PC build requests! It is in your best interests to make your own topic so you can get multiple suggestions and input from the community rather than just my own. Thanks again.

Sample Builds

Here are some sample builds that are reliable, but may not be cost-optimized builds. These builds were created on September 9, 2018; feel free to "edit this part list" and create your own builds.

Sorry for the lack of updates. I recently got a new job where I work 12 hours/day for 7 days at a time out of the city. What little spare time I have is spent on grad school and the gym instead of gaming. So I've been pretty behind on the news and some might not be up-to-date as my standards would have been with less commitments.

The problems BitEsprit solves

BitEsprit is marketing itself as "The First All-In-One Cryptocurrency Exchange" and it is meant to be one through the implementation of FIAT to crypto trading.
Not only you'll be able to trade your FIAT for Bitcoin, but also for any other alternative currency available on the platform, this opens up a really liquid cash gateway and should help further decoupling BTC from all the other good and valid projects, helping the whole market mature and safeguarding a lot of investors doing proper research and getting into good entry points in new and exciting projects which won't tank together with Bitcoin thanks to the new added liquidity.
Not only that will help in the bigger scheme of things, but there will also be quite a bunch of nice features which you won't feel like being without after you're going to get used to them.
All that, in one only exchange, do make it an actual All-in-one solution.

WeSellCrypto is back!

Hi all - Some of you may have used our service previously to purchase Bitcoin & other altcoins via PayPal.
Unfortunately PayPal has not changed its stance regarding sale of cryptocurrency, but we have partnered up a payment processor to accept 3D-Secure credit cards in many regions (currently excl. US, Canada, Japan, China-- full list can be found on our website - www.wesellcrypto.com).
We offer simple verification requirements (simply email with some basic info (name, country, etc.) for purchasing up to $15 per day. Larger limits do require ID verification, approved within 24 hours. Once approved, you can purchase any time going forward.
Some benefits to our service:
I would argue we have one of the best reputations for non-traditional purchasing. Feel free to research around various subreddits (dogecoin, particularly) and find testaments to our consistent service for three years up until our downtime from last June.
Right now we're only seeing 1-2% of the transaction volume we previously had via PayPal but are hoping to see continued growth so we can return to at least our break-even point and continue offering our service.
If our use case meets some of your needs, I hope you will check us out. Happy to answer any questions.

Two 6950's in the same rig. Why is one 90C+?

Why I have decided to invest in OmiseGo (OMG) now.

I found out about this project last week, though recall seeing their name pop up earlier in the month because of their crowdsale. Since then, I have sold 50% of my shares in other projects, and plan to increase my position greatly next month once I gain more fiat funds. I believe as an investor, OmiseGo (OMG) shows incredible potential, with now being perfect time to invest. I say invest and not trade, as this one is for the medium to long term, and not short.
  1. Omise has been around since 2013. This is not a new company, but rather one with history, core investors (20 million in series A and B prior to their latest crowdsale) and a completely serious established operation and team (70+!). They have offices in Thailand, Japan, Indonesia and Singapore. The company provides a payment management system for businesses to accept payments through their mobile application or online store. They work with AliPay as well for example. They have the PCI DSS 3.2 (Payment Card Industry Data Security Standard) already in place since November last year.
  2. Omise has just recently acquired one of the three largest payment service providers in Thailand, Paysbuy , a licensed by the Bank of Thailand operator of e-money business, and accredited with Trustmark (DBD Verified) by the Ministry of Commerce. This provides a very well established source of active users.
  3. OmiseGO is their blockchain project : "a public Ethereum-based financial technology for use in mainstream digital wallets, that enables real-time, peer-to-peer value exchange and payment services agnostically across jurisdictions and organizational silos, and across both fiat money and decentralized currencies.” . Which to me means that they are taking all that is great in the blockchain technology, and integrating it with their offering, creating a new advanced Omise service.
  4. Other than the lead team working on OmiseGo, the following are all officially advising the project: Vitalik Buterin (ETH lead ) , Dr. Gavin Wood (ETH and Parity lead) , Vlad Zamfir (CaspeETH lead), Joseph Poon (Lightning Net lead) and Roger Ver of bitcoin.com as well as many others, including a professor of Quantitative Finance. Not aware of any other BC project that has such a list of advisors of this caliber.
  5. Jun Hasegawa, Omise’s CEO, revealed just recently that McDonald’s Thailand (over 240 locations), will be using OmiseGo’s payment channel. A big Press release regarding this news has not been released, and is expected super soon! Also quoting Jun “we're launching OmiseGO to support Omise Payments and all existing stakeholders, including our existing and future merchants, such as McDonald's in other countries in Asia - McDonald's Thailand is just the start. Through OmiseGO, all Omise merchants will be able to seamlessly accept payments in multiple currencies, including ETH or BTC or other cryptos, without needing to know what their client is paying in. And any other payment gateways, including Omise's biggest competitors, as well as global giants like Stripe or Cybersource, will benefit from using OmiseGO/OMG, and are welcome, no partnership or permission needed. The OMG chain will be an entirely public and permissionless network, connected to Ethereum.”
  6. Other than investing in OmiseGo business through their OMG token for all the reasons I detailed here, holders of OMG will also generate an extra income, and quoting Jun : “OMG is a token that secures a public permissionless POS network, whose primary use case is to host a decentralised exchange for digital fiat and crypto alike. It is backed by significant mainstream financial firms in Asia who will use it as the backend for existing digital wallets - think Venmo, Google Wallet, WeChat Pay (examples of digital wallets only) - and for hosting digital fiat tokens for their existing merchant payment network. OMG holders can use OMG to validate the network. If they validate a block correctly, they get paid the tx fees from that block (but if they validate incorrectly, they get punished). Like mining but without the need for hardware.
//
These are the main reasons why I have invested in Omise and why I feel it is a great opportunity right now with super great timing. OMG only launched last week on the exchanges, and is already available on Bitfinex, (stating that “OmiseGO is an impressive and professional project, which aims to deliver on the initial promises of blockchain technology: to revolutionize the traditional financial world. OmiseGO provides a wallet and payment network for both fiat and crypto currencies.”) as well as on Liqui and EtherDelta, though personally I would stick to the well-established Bitfinex (as I did). You can dive in with BTC, ETH and even USD. Price is really nice and low, and at a perfect entry point.
EDIT: its now also live on Bttrex!
Omise main: https://www.omise.co/ OmiseGo main: https://omg.omise.co Subreddit: https://www.reddit.com/omise_go/ Slack: http://omgslack.omise.co/
Good luck to us all.

I hate my Fucking Mining Rig - Short Story of my mining adventure (Don't really hate it)

Wanted to write a short write up on my journey of Crypto mining for some of the newer people and people who want to get into it. Not trying to discourage anyone from starting, but want to show the progression of a newbie.
So I am a good with computers and learned of Bitcoin when it was about $7 a coin. Laughed at the idea of some computer doing some math and getting some BS currency. Million dollar mistake on my part, but hindsight is always 20/20.
Anyways, Learned about ethereum in May. Bought some at around $180 and bought all the way up to $330. Now to the mining rig. Ran all of the calculations and with a 180 hashrate and 900 watts I was gonna get 6-7 Eth per month. Shit was gonna be profitable in under 3 months. I was gonna be a fucking crypto allstar and be rich as fuck!
Bought all of my parts literally the day before they were nonexistent. Literally bought the last RX480's from Amazon. Here is a list of my parts.
Asrock board Pentium dual core processor 4 Gb of ram 128 gb SSD 1200 watt Rosewill PSU 6 Sata to Molex PCI Risers (Junk) 6 RX480's - 2 Asus Strix, 4 Gigabyte Total cost - Roughly $2,500 (Pennies compared to my future ROI)
Please keep in mind that I am not posting every single miner issue that I ran into such as fucking with Wattman for a few weeks before learning about Trixx and Afterburner.
I've built computers before, so that part wasn't hard. Set everything up and get windows 10 running.
Problem 1 - Computer doesn't see all of the cards. Had to run the drivers a few times and tweak some shit, but got all 6 cards seen.
Miner hurdle (See what I did there) but off to the races. Let's get this bitch running so I can begin planning my retirement.
Get Claymore running, Got Trixx to overclock. Ran my cards at -96, 1200, 2200 fans at 85% (Cause I'm cool like that.) Major stability issues from the start. 1 card (Asus) would crash all the time. Didn't know about the watch dog feature in claymore that would restart my rig when a card crashed. Great feature but my computer would go into this state of having power, but not loading the operating system. Even if it did restart, most of the time claymore would get stuck right before setting the dag's and would just lock up. (Claymore program is awesome by the way, this was my rigs fault)
Could not get this fucking Asus card to stop crashing, even on stock settings. Sent the bitch back RMA style. Asus said something was wrong and sent me a new one.
Awesome, lets get this bitch running. I need to start looking at sick houses in Costa Rica to move to once I am rich as Fuck!
New card makes things better for a few days. Not 100% stable but better. Go to vegas for a driving thing (Race cars - Future rich guy stuff) and this mechanical demon starts crashing every few hours. Luckily I had Google remote desktop installed so I could log on and restart it or change settings in Trixx. Had to have my GF unplug it and plug it in a few times.
Get back home, fuck with this thing but still random crashes on random cards. Decide it is the PCI risers. Contact seller who will send me some more for free. Slow boat from china took two weeks to get them. They arrive but still some of them are bad. Can't seem to piece together 6 good ones.
Did some research online (Ethereum Forum and Reddit) and decided to get some new style of risers V007 6 Pin to Sata ($70) and they take a month to get here. Plug them all in and they seem to be working much better. Decent stability, But I ain't got time for fucking stock bios. Let's ramp these bitches up and get 32 MHs per card at 600 watts from the wall!
Actually flashing the bios was pretty easy. Thank you 6 pound 9 ounce baby jesus! Long story short had some major stability issues and bounced around with some different timing straps before finding the right ones. (Uber 3.1 for Samsung memory)
So now that we've got some good hash speeds and decent stability let's ramp this private ATM up a little bit by dual mining some Decred. Get dual mining up and running. go to sleep. Wake up the next morning expecting to see myself on the top 100 forbes list. look at my mining rig stats on my phone and see that it died roughly and hour after I went to sleep. Walked toward my rig on the red carpet I had just installed and saw that it was off. Flicked on the light to check it out. No light, WTF? Well I'll be god damned, no power in this whole fucking room. Checked my breakers and sure enough this metal motherfucker tripped my breaker.
No worries though. I'm smart as fuck. I'll just undervolt the shit out of it to get the power down. No way in hell I am just mining ether. I'm going balls to the wall!
As you can expect I had many days of stability issues and tripped breakers. But fuck it, I have homeowners insurance. Burning it to the ground will be covered. (Didn't happen)
My surge protector must be maxed out. Let's buy a bigger one ($25). Same issues.
Fuck Decred, I'll mine SIA, less power. Damn I'm smart.
Rig is more stable with Sia and no tripped breakers. Family medical emergency, have to fly north for a few days. But my rig has been fairly stable and I've got remote desktop if anything goes wrong.
Arrive at airport, check mining stats, rig is down. No worries remote desktop. FUCK, not responsive, no way to remote into the rig and no way to remotely power it off and on.
Lost 4 days of mining. But no worries the difficulty is only, Holy shit that's high! But the price of Ether will make up for it. Ether crashed to the $200's. Oh well, maybe a 10 room house in Costa instead of a 12. No sweat.
Get back to my house and this whore of a machine is just sitting there in a computer coma. It's on but it's not. LED lights glaring at me like "Fuck you human, I ain't doing your stupid math problems!" Fuck you machine, I'm your master. You will do my math problems and you will fucking like it.
My AMD Drivers seem to disappear and the computer goes into a coma like state. Someone on Reddit suggested using the 16.9.2 drivers. Installed and they worked better.
Still random crashing. This shitty PSU must be maxed out. Fuck you PSU, I'm getting you a little brother (EVGA 750 gold $120.)
What do you mean you have to jerry rig a second PSU so it starts without being connected to a motherboard? 2 more hours of my life wasted.
But finally some stability. On my way to being fucking rich. I start looking at people in bentley's and can only laugh. You dumb fuck, I'm gonna be way richer then you. Gonna get a Bugatti for each day of the week.
Damn this difficulty is a bitch. Fuck you Genesis Mining and your pallets of GPU's. You're killing me smalls!
But anyway, on my way to rolling around in my fuck you money!
Fuck you dag file 135, you're killing my future millions. Fuck you dag 138, you dropped me to 167 mhs.
Thank god AMD was there to save my ass with their dope ass blockchain drivers.
download, run DDU, Restart, install drivers, restart, run pixel patch, restart. Perfect, I'm in the money now! I can taste the caviar and champagne already.
Now my cards only run 4 Mhs each. WTF? Try a bunch of the other new drivers. Same shit. Roll back to 16.9.2 and they run fine, just at 167 instead of 180.
Someone on a forum said he had the same issue and did a fresh install of windows 10 and it worked.
So I'll just reformat my SSD (Windows wouldn't do a fresh install within the operating system. Fuck you Bill Gates! Gonna buy you once I get this thing running at 180.)
Format SSD, plug back in, throw in my gangster ass boot USB drive. Ramdisk error. Fuck you Bill Gates! Reformat SSD multiple times, lots of forum reading. Install windows from another computer through command prompt (I'm a coder now as well.) This shit has got to work, I did it in command prompt bitches!
Same fucking error. Now down to an 8 bedroom house in Costa and only 6 Bugattis.
Let's try unplugging my 6 cards and see if that works. Thank you 6 pound 9 ounce baby jesus. Windows installed.
New drivers work and I'm back at 180! Raking in the cash now.
With those speeds my Asus cards crashed. Had to dial down the hashrate to 177.5 for them to be stable. So now going to use some commands in claymore to run the Asus cards at lower speeds while letting my other cards mine harder.
I wrote this to let people know that mining isn't all Bugatti's and caviar. These machines are fickle little cunts that do what they want. No system is the same. So when you post on a forum, people will give you advice on what may work. But what works for them, may not work on your rig. In the end it's up to you to figure it out.
I have spent countless hours after work and on weekends working on this bitch. Hell I've probably spent a few hours just staring at it and thinking about all of the ways I could destroy it slowly.
While I love Etheruem and do value the knowledge gained, I would have made more money just buying Eth and holding.
The guys you see on youtube building sick rigs with crazy specs have been at it for a while. They have worked through the process and know how to solve all of the problems. You have not and will have to work them out on your own.
My whore of a rig will pay for itself soon. But I would suggest that if you want to start building a new mining rig. Check the difficulty chart and make sure you have tons of free time to fuck with it.
I'd post my wallet address for donations since I just saved you $2,600. But I am afraid hackers will steal my monies :)
Hope you enjoyed my mining life story from the past few months.

Bitcoin adoption - What's preventing it?

I think it is time we compile a comprehensive list of reasons why big corporations are not accepting bitcoin as additional mode of payment. I know many of us are focussed on creating awareness among regular people and that is all good but I think it is more important to create awareness among corporate world so they start adding bitcoin as payment option.
There is no harm in adding bitcoin as additional mode of payment, yet not many are doing. So, definitely there is something that is holding them behind. Therefore, I though we should start compiling the reasons, so we can address them in any way possible as a community. Let us know what you think might be the reason.. Merry Chirstmas!

I had like 3 friends ask me how to build a PC in the past week so I made this to help them.

(Reddit Edit: Help my improve the document with productive constructive comments on what I got wrong or messed up! Im only human lol
Also a lot of this is supposed to be kinda humorous. I didn't think I had to say that but, hey, its the internet.
I appreciate the positive and productive comments! )
Beginners basic guide to building your own PC as of early 2018
(EDIT: Sorry for being a MSI/Corsair Fanboy)
Heres a collection of thoughts to consider when building your own personal PC
As always Id personally use PCPartPicker.com to configure your parts and for further thoughts on compatibility.
First off building a computer is 100% based around what you plan to use the computer for.
Here are a few uses and generic ideas of what to go for. Audio Editing: Lots of small tasks that need to be completed quickly without lag. - Fast Processor( >4GHZ) - Fast RAM (MHZ) -At least 16 gigs! - Fast Storage, SSD manditorily - M.2 or PCI for best performance. - Shitty Graphics card, graphics card there only to keep the cpu from doing other tasks when working. - Can be a few generations or years old. - Many screens for lots of plug in windows to be open Video Editing: Lots of large to render and files to read. - Multi core processor the more the merrier - SSD for fast read/write of large video files. - Insane graphics card, AMD graphics cards are debatibly better but the nvidia Quadro series are specific for video rendering. Gaming: No more than 4 cores intense graphics card - 92% of games are not coded for more than 4 cores so why spend the extra money for it. - SSD for quick load screens - Nvidia cards, 10 series, the higher the number the better. Titan cards for MAXIMUM OVERDRIVE! Coding: quick processor for lots of small tasks. Ergonomic peripherials? - Dear god please dont use a mechanical keyboard so that your coworkers dont kill you. Home office: Everything can be a few gens behind so you can get the best power per dollar spent. - Sorry that Gateway doesnt exist anymore. I guess try Dell... 
Parts (Expensive Legos)
CPU (tells things to go places and outputs data) Basically three main routes to go for: Intel, AMD, or ASIC. Intel - Gaming, Data center, Hackintosh Pros: Cooler, Faster speed (GHZ), short small tasks faster Cons: $$$$, less cores AMD - Gaming, Personal Computing, Large task processing Pros: Lots of cores, better price per performance, faster processing of large tasks Cons: Hot chips, large chips?, compatibility issues with MacOS. ASIC - "Application-specific integrated circuit" Pros: Does the task that they are made to do insanely efficently, great for mining. Cons: Literally does nothing else. Holy hell these are expensive, very hot (fans will get loud) CPU Cooler (Im a big fan) Most come with an in box cooler that are ok but please buy aftermarket. In Box - the free shitty cooler that comes with the processor. Pros: Free. Cons: Ugly, makes chip run hot, hard to clean Air cooler - oldest type of cooler but new designs are highly efficent. Pros: Only cooler that has the possibility of being 100% quiet, most likely cheaper Cons: large, if cooler isnt large enough for the chips thermal output the fans will be loud. Liquid - Custom pipes are beautiful, AIO is easy to install and offers similare performance. Pros: Looks cool, great temperatures, "quiet" Cons: Water pump has possibility of being loud, possible spills Phase Change - uses the technology of refridgerators to cool the chip Pros: Can overclock until the chip breaks. (whats colder than cold? ICE COLD!) Cons: Loud (compressor noise), Large pipes, just why.... Motherboard (the convienacnce store of computer parts) Really just about what type of I/O you want. - MAKE SURE FORM FACTOR FITS YOUR CASE! (or vice versa) - Look for PCI lanes for expansion. - How many graphic cards do you have? - PCI based interfaces? - PCI SSD? - PCI DAC? - PCI WIFI? - USbs? Network? Audio? - How many lanes of RAM? - DOES IT FIT YOUR PROCESSOR!?! (really tho) - M.2? - How many sata interaces? Good Brands: MSI, ASUS, Gigabyte Bad Brands: AS(s)Rock, Dell Memory (Dory) - The more the merrier - No less than 8gb for a functional windows machine (16 gb to never have a problem) - Use all the lanes your computer has to offer! the more lanes to access the faster the data can travel! -Imagine drinking a milkshake. If the straw is wider you can drink more of the milkshake than a skinny straw. - Faster MHZ for faster data access but give minimal performance differances - Please get ram with heat spreadders unles youre building a server with high airflow. - Make sure the type (DDR3 or DDR4) of RAM matches what your processomotherboard call for. Good Brands: Corsair, G.Skill, Ballistix Storage (Grandpa that remembers everythign about how things used to be but takes forever to learn a new tasK) Speed or massive storage? slower is cheaper. Golden ratio of speed/storage/price is 250-500 gb SSD and a 1+ tb disk drive. *Max speeds listed are for a single drive not RAID* Hard Disk Drives (HDD) - Cheapest and slowest - read/write speeds of < 0.5gb/s - 7200+ RPM or GTFO - Higher Speed drives can access data faster. - Do not move while powered up. physical parts will break. - Larger Cahche = faster Read/Write Speeds Pros: Cheap, Holds massive amounts of data Cons: Slower than molasses in a frezer Reputible Brands: Seagate, WD Solid State Drives (SSD) - necessity for quick boots and fast load screens (can only be re-written to so many times) - SATA based (2.5 inch)- Read/Write speeds capped @ 6 gb/s Pros: Most economical, form factor fits with old computers, Cons: "Slow" compared to other ssd's (but stil 12 times faster than a HDD) - M.2 based - Read/Write speeds capped @ 10 gb/s Pros: Size of a sick of gum! High End but not too expensive to be out of reach. Cons: Expensive for any size over 500 gb - PCI based - Read/Write speeds capped @ 20 gb/s for PCI3, x4 Pros: HOLY BANDWIDTH BATMAN! Faster than that little creepy ghost thats always in the corner of you eye Cons: You might have to take out a loan to buy one. *takes up a x4 PCI Lane* Reputible Brands: Samsung! Corsair, Plextor, Intel, Kingston, Crucial Video Card (that one kid that has thick glasses and is really good at math) - A regular old PCI card that handles all of the video rendering and output for your computer. - ASIC PCI cards. - The PCBs and chips are patented by two main companies but the differances come from line up and varying manufacturer cooling devices. - The more memory the better -NVIDIA (Team Green) Great for gaming, has specific card series for intensive rendering. Lazy driver updates. - Gaming - 900 series - Cheap - Low performance - Can play any video game made befrore 2010 on max settings - 1000 (ten) series - Expensive (thanks bitcoin miners...) - Great for VR! - Video Rendering -Quadro Series - Gaming and Rendering - Titan X - Maxwell based chip same as 900 series cards - Titan XP - Pascal based chip same as 10 series cards -AMD (Team Red) Underdog does the same thing but slighly worse and cheaper. (except video rendering) - Gaming - RX 400 series - Cheap - Hot - RX 500 series - Cheap - Ok at VR and deacent gaming frame rates. - Not bad but not particularly great either. - Video Rendering - Fire Pro series - Gaming and Rendering - Vega series -Good luck finding one to buy lmao Case (Fancy clothing for your parts!) - Similar to human clothing you want it to do a few main things really well with compromises for each extreme. - Durability - Steel - Incredibly durable - Creates Farady cage for components - Heavy af - Magnets, just magnets.... - Rust over time - Aluminium - Light - East to bend for modding or "physical maintenance" - Less likely to rust - Huzzah for Farady cages! - Plastic - Just dont - no electrical Ground - no faraday cage - Light AF! - Breath (Airflow) - positive internal airflow! - larger fans push the same amount of air with less speed/noise - Looks - Window? - RGB - Cool Paint? - Fit all your parts - graphics card length/ clearacne - support for liquid cooling raiators? - How many spots for HDD/SSDs - Motherboard format - Cable management! Power Supply (FIGHT MILK) - Rule of thumb: BUy Powersupply that outputs 1.5 times the wattage that you need. - You can walk further than you can you can run. - The PSU can casually output 50-75% power for much longer than at 90-100% (without failure) - If you never demand enough wattage for it to get hot the fan doesnt have to turn on therefore making it quieter. - Modular means you can remove/replace the cables from the PSU. Reputible Brands: Corsair, EVGA Optical Drive (motorized cup holder) - You can download most things today so I'd suggest against it unless you really NEED to watch/write DVD's/CD's Operating System (software that makes everything work) Windows (Always Updates) - Compatible with just about everything - Easy to learn to code on! - POS inital browser - Likely to get virus's Linux (Penguins are cute) - Unique - takes less resources to run - Barebones - Incredibly personalizable! - Compatibility issues with just about everything MacOS (Linux but more annoying) - It is legal! - Great for art and your grandma that doenst know how to use computers! - User friendly - Compatibility issues with various hardware - Confusing/Limiting coding structure Peripherials (cables everywhere!) - Keyboard (higer Polling rate is better) - Mechanical (key is pressed at an exact stroke length every time - Mouse (Higher Polling rate is better) - more buttons = better? - DPI (Dots Per Inch) - In theory, if a mouse has 1600 DPI, then, if you move your mouse one inch (2.54 cm), the mouse cursor will move 1600 pixels - Higher DPI the faster your cursor is able to be moved. - Monitor - In theory the human eye cant see faster than 60 frames per second. - Keep in mind Pixel ratio! - 4k screen that is 22inches will have more pixels in a square inch than a 4k screen that is 28 inches. - Interface? - DVI (Analog) - thumbscrews..... - can do two monitors with one port! - support for 4k - VGA (Analog) - thumbscrews... - max resolution is 1440p - Display Port (digital) - nice button clip - supports 4k - HDMI (Digital) - 1.2 or higer supports 4k - DAC/Speakers/Headphones - Dont even get me started - Microphone - Dont get me started PT.2 Other (other) - UPS (uninterruptible power supply) Just a battery that allows your computer to have some time if the power ever goes out so that you have time to save your work. - Cable Organization materials! - Zipties - velcro - LED LIGHTING! - Manditory - Extra/Better fans - More pressure, less woosh - IFIXIT Pro Tech Toolkit - becasue who buys just one torx wrench. - Cute kitten mousepad - Yes, it has to be a cat. Dont argue 
This is a very general entry into building computers and what you should buy/look for. If you have any questions/comments send me an e-mail!

Has anyone ever thought of a new type of payment system 2

Has anyone ever thought of a new type of payment system 2

https://preview.redd.it/skvs6r0gvzz21.png?width=1958&format=png&auto=webp&s=b106fe9a7cc282cce9d5b2451cfad10601f43855
I have received a lot of feedback after my post "Has anyone ever thought of a new type of payment system?". Thanks to all of those who tried to analyse and set out their vision. Special thanks to those who doubted my competence and brought out their own understanding of the processes and entered into a dispute. And very special thanks to those few who used only accusations in scam and profanity as arguments - they made me understand that it is impossible to explain to everyone, no matter how hard you try. Nevertheless, thanks to the first two categories It became clear to me that the information presented in the article is incomplete and needs to be described in more detail, but of course, only to the first two categories.
Disclaimer
The chain of relationships listed below has been greatly simplified to facilitate understanding. Consciously omitted many things, the description of which would take a huge amount of space.
Introduction.
Majority who oppose technology do not look up to the future and, most importantly, have no idea about the past. Technologies are similar to science, innovation, they can frighten with their ideas and cause rejection in the beginning. After adoption, adherents become ardent followers and hardly recognise something new that goes against already established convictions. Bethink of Christianity - some tried to eradicate it, destroy it, burn Christians on fires, feed them to lions, killed unarmed people in gladiatorial battles. Later, Christianity itself has struggled with dissent - Galileo, Copernicus, Bruno. Examples that are closer to us in time are cars with internal combustion engines, telephone, radio, airplanes ... all these inventions met resistance at the stage of their appearance and caused a storm of ridicule and aversion and misunderstanding of the “use cases”. Not such a distant example with the advent of the Internet, when the web pages were so simple and uninformative that the majority of the population of the Earth simply did not take it seriously and, moreover, did not see its use. There are many such examples. And even the temporary absence of the “use cases” does not indicate the uselessness or irrelevance of the technology, it indicates that the world is not ready yet to apply the technology at the moment due to habits, beliefs, interests, and sometimes, incompetence. The topic of the blockchain and cryptocurrency in particular is susceptible to reproaches in the absence of its practical use, which is understandable due to the youth of the technology and its initial stage of formation and development. In addition, in some cases, the line should be drawn between the cryptocurrency and the blockchain technology itself, since the majority of people do not see the technology itself, but only its derivative in the form of a mass of coins, most of which are dummies and really have no application. But, nevertheless, even at the present stage of development of the blockchain technology, the talk about the lack of “use cases” indicates not owning information, well, or not wanting to see the obvious - merchants, Jaguar, Facebook...
All this applies to today's financial sector conditions. And that is obvious, because the technology of making payment via plastic cards comes from the 1950s. Several generations of people grew up on the existing system and have a long-established habit of using it. Several generations of banks earn huge amounts of money on commissions that customers pay. Several generations of companies providing these payments have changed leadership. Some have gone, and those who remain hold such strong positions and their profits are so huge that they have no reason to rejoice in large numbers for the technology - after all, they can shake their incomes, and the scale of these companies does not allow them to respond quickly to changing time. But even with this in mind, the interest of these companies in technology is obvious. Such pillars like VISA, MC, WU, Barklays, BBVA and many others either look for ways to introduce the blockchain technology or already use it. But, nevertheless, attempts to introduce the technology are still being applied to the existing payment system, credit, and financial relations. Now, I will introduce my own arguments and briefly describe essentially new approach to making payments.
Part One - "What are the existing payment systems and how do they work."
In today's payment system relations, there are six subjects:
  1. Client - buyer of the goods;
  2. Bank-Issuer, where the client keeps his money;
  3. Seller of the goods (Merchant), which accepts the client's card for payment;
  4. Bank Acquirer, where the Merchant keeps his account;
  5. Switch - payment system (PS) that connects the Issuer and Acquirer (for ease of understanding - VISA, Master Card, AMEX, Union Pay, etc);
  6. Processing center - an enterprise certified by the PS, which processes payments of the Bank-Acquire and Bank-Issuer;
  7. There are still various clearing and settlement centers) authorized by payment systems and local securities in different countries to carry out payment operations and perform clearing processes, i.e., reducing settlements between banks' balances, but we will omit them for simplicity of explanation and understanding, since these functions Centers can be performed by Bank-Equal and, in our example, to simplify the description.
Suppose that an American client, whose account is held in a certain American bank, came to Australia to buy coffee. He pays with his plastic card, putting it to the merchant's terminal (POS-terminal). Money from a client is in the account of an American bank, how does the Merchant receive it? POS-terminal Merchant belongs to the bank in which the Merchant holds its account in Bank Acquirer.
  1. The terminal reads the client card and sends information about it to Bank-Acquirer;
  2. Bank-Acquirer is not connected in any way with the Bank-Issuer, therefore, it cannot request directly the payment, and the transfer directly from America to Australia will not allow the client to enjoy hot coffee. Therefore, Bank-Acquirer asks the Processing Center about the availability of the required balance on the client's card;
  3. The processing center requests Switch for the availability of the required balance on the client card;
  4. Switch contacts the Bank-Issuer and requests the availability of the necessary balance on the client's account;
  5. Bank-Issuer confirms to Switch the existence of the required balance (or does not confirm, then the refusal of the transaction occurs);
  6. Switch confirms to the Processing Center the presence of the required balance on the client’s card (account) and gives a signal to the terminal to confirm the payment;
  7. The processing center confirms to the Bank-Acquirer the existence of the necessary balance on the client’s card (account) and gives a signal to the terminal to confirm the payment;
  8. The client has paid and he leaves satisfied;
  9. Bank-Acquirer transfers the sum of purchase to the merchant's account;
  10. The Bank-Acquirer transfers information about the payment made to the Processing Center and issues a claim for compensation of the payment amount;
  11. The processing center transfers information about the payment the Bank-Acquirer made to Switch, since, in fact, the Bank-Acquire has transferred the money to its merchant;
  12. Switch pays from its funds to the Bank-Acquire (for simplicity of explanation, we omit here the clearing system of settlements through authorized clearing centers (in fact, the process is much more complicated);
  13. Switch bills the Bank-Issuer (for simplicity of explanation, we omit here the clearing system of settlements through authorized clearing centers (in fact, the process is much more complicated);
  14. Bank Issuer paid to Switch (for simplicity of explanation, we omit here the clearing system of settlements through authorized clearing centers (in fact, the process is much more complicated)
We can introduce scheme:

Traditional processing scheme
Switch is an intermediary between all the parties of the entire system and receives a commission for all transactions. Who can even imagine the infrastructure setting expenses to operate the processes of settlement analysis, comply with the requirements of KYC / AML, match modern safety requirementsfor the launching of data centers around the world. Of course, commission is the source to operate.
For ease of explanation, we imagine that the Switch is the processing center.
Conceptually, costs can be divided into Organizational and Technical
  1. Organizational:
  • creating jobs for staff of specialists, most of which are expensive: system administrators, engineers, 24 hrs. support services and an authorization center;
  • making decisions of the placement of software and hardware systems. Organization of your own premise(s) or placement of your software and hardware systems in the premises of a third-party company (outsourcer);
  • development of a system for controlling access to the premise(s) of the processing center, including such procedures as: organizing access monitoring, employees to the processing center premises, developing work procedures in high-security areas, etc .;
  • making a decision on the choice of the supplier of software necessary for building a processing center certified by an appropriate payment system;
  • deciding on the choice of suppliers of related services (for example, courier services and / or gateways for sending SMS or PUSH messages, and the subsequent construction of contractual and working relations with it;
  • development, coordination and implementation of procedures for correct work with cryptographic equipment and quantities, and issuance of domestic regulations governing the work of security officers (security officers);
  1. Technical:
  • The purchase of hardware (system units, hard drives, RAM (random access memory, Does RAM), uninterruptible and backup power supplies, racks, etc.),
  • the purchase of the server software (operating systems, database systems, etc.), including license fees vendors of such software,
  • the purchase of cryptographic equipment necessary for the generation and correct processing of operations on cryptographic values, such as CVV or CVC;
  • information security solutions (ensuring compliance with the requirements of PCI DSS, federal laws, protection document management systems);
And such (all of the above) costs must be borne constantly, if we are talking about expanding your presence. Switch (processing centers) can cover these costs only with a part of the commission for the implementation of monetary transactions, which is borne by the other participants in payment relations.
Since the recipient of the client’s money is ultimately the merchant (seller / trader), it is logical that the entire amount of the commission is charged to him. This commission is called Interchange Fee (hereinafter - IF), it can be from 0.7% to 5% depending on the riskiness of operations. For example, an ordinary store, on average, pays 1.5% of IF, while, for example, an online store can pay 5%.
It is noteworthy that for the client this commission is not visible and in 90% of cases he does not even know about it. Such a commission is included in the price of the goods. That is, by selling you a product for $ 100, the Merchant will receive (if he pays IF = 2.24%) $ 97.76. The Switch distributes these $ 2.24 between the participants as follows:
Traditional Processing (TP)
Consumer pays$ 100.00Overall Fee$ 2.24Issuer Receives$ 1.80Acquirer Receives$ 0.31Visa Receive$ 0.13Merchant Receives$ 97.76
o we pulled how the current payment system functions. Now, in detail about how this can function using blockchain technology.
Part 2 - “New payment system and how it works.”
One of the main significant achievements of blockchain technology is excluding of intermediaries. In the field of finance, this gives special advantages — cost savings.
A new type of payment systems based on blockchain can successfully use this advantage. Naturally, there are necessary assumptions for the use of this technology in the financial sphere:
  1. It is necessary that the two contractors and the Merchant are in the same blockchain;
  2. Merchant must have a POS terminal transmitting information to the blockchain;
  3. Banks must open clients wallets and implement data exchange between blockchain and ABS (automated banking system) of the bank,
  4. In order to comply with the requirements of KYC / AML, private keys are kept by the bank;
  5. Must be a blockchain base Switch to physically conduct clearing of payments between the Merchant and the Issuing Bank.
Just as in the situation above with our American customer buying coffee in Australia: the same American and Australian banks, but they are in the same blockchain. It is convenient to send just cryptocurrency, of course, but the question immediately arises - “Why does the Merchant need it and what will it do with it? How will he solve the issue of currency fluctuations? ”Immediately make a reservation that I will not describe the technology here thoroughly, since this is a commercial secret, but briefly, I will describe the principle of operation.
So, two banks are in the same blockchain. In the blockchain, there is a special protocol implemented that allows to “mirror” the client fiat accounts to the blockchain, thus, the exchange of information between the client’s account and the blockchain takes place on an ongoing basis.
  1. The client brings the card to the merchant's terminal; the terminal requests the availability of the required amount in the blockchain. If the required amount is available (if not - decline), the protocol starts the transaction, which the client confirms (fingerprint);
  2. The Fiat amount on the client’s account of the Bank-Issuer is held by the Bank (thus collaterizing the amount of cryptocurrency to be transferred);
  3. The required, “mirror” amount in cryptocurrency is transferred to the Merchant's wallet;
  4. Merchant's wallet, having received the transaction, sends information to the Merchant Terminal, payment is accepted;
  5. The American enjoys coffee. Now, the Merchant has a cryptocurrency on the wallet, Bank-Issuer hold amount in fiat currency;
  6. Switch (the very same payment system), “buys” the cryptocurrency for the Australian dollar from the Merchant in Australia, in America, the Bank-Issuer transfers Switch a collaterized amount of USD.
Again, for ease of explanation, I omit some points that accompany the clearing process.
The scheme of the work of the new payment system can be represented as follows:

Decentralized Processing scheme

What is the advantage?
  1. Switch can set the price for its services significantly lower than existing today, because it saves on the entire infrastructure - hardware, data centers, personnel.
  2. The Bank-Acquirer does not lend, in fact, the Merchant’s account, so its remuneration can be significantly reduced. In addition, in this chain of relations Bank-Acquirer is not needed at all, because the Merchant can hold an account immediately in the Switch;
  3. There is no need to create processing centers, which means that you do not need to bear the costs of creating infrastructure;
  4. The cost of the transaction in the blockchain network is from $ 0.01- $ 0,05;
  5. Transaction time - from 1 to 5 seconds;
In numbers, everything looks like this:
Decentralized Processing (DP)SavingConsumer pays$ 100.00Overall Fee$ 0.650-70.98%Issuer Receives$ 0.35Acquirer Receives$ 0.30Switch$ 0.13Merchant Receives$ 99.22-65.18%
The savings in the process are obvious! The merchant receives 65.18% more money on his account. Bank-Acquirer receives almost as much as in the scheme with traditional processing. The Bank-Issuer receives less remuneration, but under a scheme with decentralized processing, it bears much less expenses on security of payments, payment verification, customer verification, respectively, personnel costs, which always constitute the bulk of costs, decrease.
Conclusion.
In addition to the above economic factors, a new type of payment system has another, perhaps one of the most important advantages compared to traditional PS - to provide an infrastructure for the issuing of plastic cards for issuing banks is much cheaper than traditional PS.
The main problem that the new PS will face is the speed of processing payments. VISA today can handle 150 million transactions per day or 1,700 transactions per second with the possibility of securing up to 24,000 transactions per second. Until a certain time, no public blockchain could solve this problem. Now, compared to the published data on the speed of other blockchains on main net, NeuronChain can confidently claim 2nd place at its speed of 100,000 tps, so this issue is no longer a deterrent.
Of course, to implement the payment relations described above, it is necessary to do a great deal of work, not only on the IT part, but also on technical and legal issues, to spend tremendous efforts on marketing and explaining the processes of the participants in the relationship. But impossible is nothing. In any case, the blockchain technology gives us this opportunity.

Has anyone ever thought of a new type of payment system - 2

Has anyone ever thought of a new type of payment system - 2

https://preview.redd.it/joq0knsisvx21.png?width=1958&format=png&auto=webp&s=fa6c9f6cce01bd413fc961fe54bb9f950e274112
I have received a lot of feedback after my post "Has anyone ever thought of a new type of payment system?". Thanks to all of those who tried to analyse and set out their vision. Special thanks to those who doubted my competence and brought out their own understanding of the processes and entered into a dispute. And very special thanks to those few who used only accusations in scam and profanity as arguments - they made me understand that it is impossible to explain to everyone, no matter how hard you try. Nevertheless, thanks to the first two categories It became clear to me that the information presented in the article is incomplete and needs to be described in more detail, but of course, only to the first two categories.
Disclaimer
The chain of relationships listed below has been greatly simplified to facilitate understanding. Consciously omitted many things, the description of which would take a huge amount of space.
Introduction.
Majority who oppose technology do not look up to the future and, most importantly, have no idea about the past. Technologies are similar to science, innovation, they can frighten with their ideas and cause rejection in the beginning. After adoption, adherents become ardent followers and hardly recognise something new that goes against already established convictions. Bethink of Christianity - some tried to eradicate it, destroy it, burn Christians on fires, feed them to lions, killed unarmed people in gladiatorial battles. Later, Christianity itself has struggled with dissent - Galileo, Copernicus, Bruno. Examples that are closer to us in time are cars with internal combustion engines, telephone, radio, airplanes ... all these inventions met resistance at the stage of their appearance and caused a storm of ridicule and aversion and misunderstanding of the “use cases”. Not such a distant example with the advent of the Internet, when the web pages were so simple and uninformative that the majority of the population of the Earth simply did not take it seriously and, moreover, did not see its use. There are many such examples. And even the temporary absence of the “use cases” does not indicate the uselessness or irrelevance of the technology, it indicates that the world is not ready yet to apply the technology at the moment due to habits, beliefs, interests, and sometimes, incompetence. The topic of the blockchain and cryptocurrency in particular is susceptible to reproaches in the absence of its practical use, which is understandable due to the youth of the technology and its initial stage of formation and development. In addition, in some cases, the line should be drawn between the cryptocurrency and the blockchain technology itself, since the majority of people do not see the technology itself, but only its derivative in the form of a mass of coins, most of which are dummies and really have no application. But, nevertheless, even at the present stage of development of the blockchain technology, the talk about the lack of “use cases” indicates not owning information, well, or not wanting to see the obvious - merchants, Jaguar, Facebook...
All this applies to today's financial sector conditions. And that is obvious, because the technology of making payment via plastic cards comes from the 1950s. Several generations of people grew up on the existing system and have a long-established habit of using it. Several generations of banks earn huge amounts of money on commissions that customers pay. Several generations of companies providing these payments have changed leadership. Some have gone, and those who remain hold such strong positions and their profits are so huge that they have no reason to rejoice in large numbers for the technology - after all, they can shake their incomes, and the scale of these companies does not allow them to respond quickly to changing time. But even with this in mind, the interest of these companies in technology is obvious. Such pillars like VISA, MC, WU, Barklays, BBVA and many others either look for ways to introduce the blockchain technology or already use it. But, nevertheless, attempts to introduce the technology are still being applied to the existing payment system, credit, and financial relations. Now, I will introduce my own arguments and briefly describe essentially new approach to making payments.
Part One - "What are the existing payment systems and how do they work."
In today's payment system relations, there are six subjects:
  1. Client - buyer of the goods;
  2. Bank-Issuer, where the client keeps his money;
  3. Seller of the goods (Merchant), which accepts the client's card for payment;
  4. Bank Acquirer, where the Merchant keeps his account;
  5. Switch - payment system (PS) that connects the Issuer and Acquirer (for ease of understanding - VISA, Master Card, AMEX, Union Pay, etc);
  6. Processing center - an enterprise certified by the PS, which processes payments of the Bank-Acquire and Bank-Issuer;
  7. There are still various clearing and settlement centers) authorized by payment systems and local securities in different countries to carry out payment operations and perform clearing processes, i.e., reducing settlements between banks' balances, but we will omit them for simplicity of explanation and understanding, since these functions can be performed by Bank-Acquirer and, in our example, to simplify the description).
Suppose that an American client, whose account is held in a certain American bank, came to Australia to buy coffee. He pays with his plastic card, putting it to the merchant's terminal (POS-terminal). Money from a client is in the account of an American bank, how does the Merchant receive it? POS-terminal Merchant belongs to the bank in which the Merchant holds its account in Bank-Acquirer.
  1. The terminal reads the client card and sends information about it to Bank-Acquirer;
  2. Bank-Acquirer is not connected in any way with the Bank-Issuer, therefore, it cannot request directly the payment, and the transfer directly from America to Australia will not allow the client to enjoy hot coffee. Therefore, Bank-Acquirer asks the Processing Center about the availability of the required balance on the client's card;
  3. The processing center requests Switch for the availability of the required balance on the client card;
  4. Switch contacts the Bank-Issuer and requests the availability of the necessary balance on the client's account;
  5. Bank-Issuer confirms to Switch the existence of the required balance (or does not confirm, then the refusal of the transaction occurs);
  6. Switch confirms to the Processing Center the presence of the required balance on the client’s card (account) and gives a signal to the terminal to confirm the payment;
  7. The processing center confirms to the Bank-Acquirer the existence of the necessary balance on the client’s card (account) and gives a signal to the terminal to confirm the payment;
  8. The client has paid and he leaves satisfied;
  9. Bank-Acquirer transfers the sum of purchase to the merchant's account;
  10. The Bank-Acquirer transfers information about the payment made to the Processing Center and issues a claim for compensation of the payment amount;
  11. The processing center transfers information about the payment the Bank-Acquirer made to Switch, since, in fact, the Bank-Acquire has transferred the money to its merchant;
  12. Switch pays from its funds to the Bank-Acquire (for simplicity of explanation, we omit here the clearing system of settlements through authorized clearing centers (in fact, the process is much more complicated);
  13. Switch bills the Bank-Issuer (for simplicity of explanation, we omit here the clearing system of settlements through authorized clearing centers (in fact, the process is much more complicated);
  14. Bank Issuer paid to Switch (for simplicity of explanation, we omit here the clearing system of settlements through authorized clearing centers (in fact, the process is much more complicated)
We can introduce scheme:

Traditional Processing scheme
Switch is an intermediary between all the parties of the entire system and receives a commission for all transactions. Who can even imagine the infrastructure launching expenses to operate the processes of settlement analysis, comply with the requirements of KYC / AML, match modern safety requirements for the launching of data centers around the world. Of course, commission is the source to do it.
For ease of explanation, we imagine that the Switch is the processing center.
Conceptually, costs can be divided into Organizational and Technical
  1. Organizational:
  • creating jobs for staff of specialists, most of which are expensive: system administrators, engineers, 24 hrs. support services and an authorization center;
  • making decisions of the placement of software and hardware systems. Organization of your own premise(s) or placement of your software and hardware systems in the premises of a third-party company (outsourcer);
  • development of a system for controlling access to the premise(s) of the processing center, including such procedures as: organizing access monitoring, employees to the processing center premises, developing work procedures in high-security areas, etc;
  • making a decision on the choice of the supplier of software necessary for building a processing center certified by an appropriate payment system;
  • deciding on the choice of suppliers of related services (for example, courier services and / or gateways for sending SMS or PUSH messages, and the subsequent construction of contractual and working relations with it;
  • development, coordination and implementation of procedures for correct work with cryptographic equipment and quantities, and issuance of domestic regulations governing the work of security officers (security officers);
  1. Technical:
  • The purchase of hardware (system units, hard drives, RAM (random access memory, Does RAM), uninterruptible and backup power supplies, racks, etc.),
  • the purchase of the server software (operating systems, database systems, etc.), including license fees vendors of such software,
  • the purchase of cryptographic equipment necessary for the generation and correct processing of operations on cryptographic values, such as CVV or CVC;
  • information security solutions (ensuring compliance with the requirements of PCI DSS, federal laws, protection document management systems);
And such (all of the above) costs must be borne constantly, if we are talking about expanding your presence. Switch (processing centers) can cover these costs only with a part of the commission for the implementation of monetary transactions, which is borne by the other participants in payment relations.
Since the recipient of the client’s money is ultimately the merchant (seller / trader), it is logical that the entire amount of the commission is charged to him. This commission is called Interchange Fee (hereinafter - IF), it can be from 0.7% to 5% depending on the riskiness of operations. For example, an ordinary store, on average, pays 1.5% of IF, while, for example, an online store can pay 5%.
It is noteworthy that for the client this commission is not visible and in 90% of cases he does not even know about it. Such a commission is included in the price of the goods. That is, by selling you a product for $ 100, the Merchant will receive (if he pays IF = 2.24%) $ 97.76. The Switch distributes these $ 2.24 between the participants as follows:

Traditional Processing Sum
Consumer pays $ 100.00
Overall Fee $ 2.24
Issuer Receives $ 1.80
Acquirer Receives $ 0.31
Visa Receives $ 0.13
Merchant Receives $ 97.76
So we pulled how the current payment system functions. Now, in detail about how this can function using blockchain technology.
Part 2 - “New payment system and how it works.”

The savings in the process are obvious! The merchant receives 65.18% more money on his account. Bank-Acquirer receives almost as much as in the scheme with traditional processing.
