Learn from famous teachers: Dao organization comes from Cosmos, poca and other well-known open source projects as well as a number of Wall Street financial practitioners
Grounded Technology: the core research direction of blockchain developers "cross chain"
Looking at finance: building distributed financial infrastructure
Layout of mining industry: "mining machine, mine field and mine pool", and strive to build a trinity of mining giant whale in 2020
In 2020, Forbes, the most concerned blockchain 4.0 project, is about to launch its global mining plan: Forbes has released its own ASIC chip bitcoin miner, and GFS hard disk miner is under development. At the same time, Forbes deployed mines in various regions of the world, including China, Southeast Asia, the United States, Australia, Russia and other places, to protect the "consensus".
Forbes receives f2pool Based on the deployment of mining machines and mines in 2020, the Forbes plan will be launched with the strong support of internationally renowned mining pools. It is expected to build into the world's largest, most open and transparent comprehensive mine pool within three years.
Miner and quarry
Blockchain is revolutionary. It allows anyone to own and transfer assets through an open financial network without a trusted third party. There are now thousands of blockchain based assets, and the main way to produce encrypted assets is mining. "Mining", i.e. encrypted assets, represents the wealth anchored by the blockchain system, "mining" is the most direct means for all the network to obtain wealth. When the miner obtains the right to pack the blocks according to the consensus rules based on cryptography, and packages all the transactions correctly, the mining behavior can obtain the reward (token) given by the blockchain system for its honest record of the blocks, and when the blockchain system gains value promotion due to the growth and development of the participants, the token obtained by the miner will also be given higher and higher The secondary market value of. The miners produced the initial system pass. Therefore, mining industry has become the most upstream of blockchain industry.
It can be said that mining industry is the foundation of the whole blockchain industry, which determines the 0 or 1 of a blockchain system. The mining equipment we use is the miner.

The miner is essentially a computer. Personal computer is generally composed of CPU, GPU, memory, hard disk, motherboard and other devices. Mineral machinery is no exception in nature. Any mineral machinery is composed of motherboard + hard disk + mining chip. However, due to different mining machines for different algorithms of digital assets, such as GPU (or ASIC) for BTC, ETH mining, CPU for Monroe money mining, hard disk for IPFs, Bhd and other projects mining.
Forbes mining machine in the main board, hard disk, mining chip innovation, Forbes uses dpoc consensus algorithm, belongs to the hard disk mining branch. Forbes with the strongest computing power is also in the field of the Internet of things. In foreign countries, everything is connected, hundreds of millions of intelligent devices are connected with each other, and they have super computing power and stability. Forbes mining machines all over the world will be very suitable for the deployment of Internet of things protocol, and become an important component of blockchain + Internet of things.
The mine site is the offline site for the deployment and maintenance of mining machines. But for ordinary investors who want to enter the market, mining is difficult because the mining threshold is too high. Personal users want to mine, there is a huge deployment threshold and technical threshold. First of all, individuals can not get excellent electricity price, high temperature and high noise environment makes it impossible for users to mine at home. In addition, mining needs to be configured and deployed, and expensive mining machines need to be maintained regularly. Musk said that Tesla is not selling cars, but workshops. Standardization is necessary for an industry to achieve success. In the early miner Alliance Plan, Forbes launched its own BTC ASIC chip and bitcoin miner. At the same time, combined with major capitals, it created a global standardized Forbes mine, which was deployed and maintained in a unified way, greatly extending the service life of Forbes miner. According to the simulation test, Forbes I miner can operate stably for more than six years, which greatly reduces the mining cost and enables investors to obtain higher profits. Later, Forbes will log in to the Forbes hard disk miner in the ore pool after the main network goes online.
Forbes miners Alliance Program
Miner Alliance Plan: during a period of time when Forbes main network goes online, users can use collateral parallel chain assets (such as usdt, BTC, etc.) to lease computing power to deploy mining machines in global mines. In the lease term, the deposit is returned by the smart contract according to the number of days, and the mining revenue is obtained by the early participating nodes.
Due to the cross chain implementation of Forbes, a large number of nodes need to be deployed in the early days to complete the information interaction between the relay chain and the parallel chain. And with the scale of ore pool access, the marginal cost of new mining machines will be lower and lower, and the revenue will grow steadily. Therefore, Forbes started the plan of Forbes miners' alliance, realized the rapid scale of the mining pool with market funds, and realized the stable growth of mining profits.
Through the miner alliance, users can rent mining machines. In the form of "deposit contract" to ensure that each miner's fund is dedicated, and at the same time, for each miner, it is considered to realize the real deposit settlement on schedule through the blockchain intelligent contract. After the Forbes miner generates mining revenue, the user will get kusd stable currency. In the operation plan of Forbes Dao, all the miners who join the mine have the opportunity to convert part of the profits into GFS with unlimited potential.
It is estimated that the early participants in the Forbes miner's program will have more than 1.6 times the deposit during the lease term of one year. It was asked where such gains came from. In fact, as a representative project of blockchain 4.0, the appreciation of GFS is inevitable. At present, the trading of GFS secondary market has increased by more than 10 times in a week. With the continuous extension of parallel chain and the continuous exploration of financial business, there is almost no doubt that the growth of GFS exceeds that of bitcoin in a year, even if it is halved. Forbes Dao mass produces Forbes super miner through the digital assets mortgaged by users. After the cost is removed, it covers more than 1.6 times of the revenue to nodes. Almost the secondary market value of GFS alone is far beyond.
In addition, the BTC value dug out in the miner's Alliance plan will become a stable support for the miner's Alliance Plan, and 2020 is known as bitcoin minus half a year. Get BTC while digging GFS. To say the least, the price of GFS has fluctuated, and the BTC dug out is actually stable. Not to mention that the layout of Forbes gold stable currency, Forbes DEX and so on has been dragged down, and the user's income is cashed at any time. Forbes' miner plan is a three-way and multi win business initiative, which is the distributed power.

GPU Mining Crash Course - START HERE!

Welcome All to the GPUMining Crash Course!
With the increase in prices in cryptocurrency, a lot of people are getting back into mining and a lot of people are brand new to the concept overall. So, I quickly wrote this crash course to help you understand what to expect and how to successfully mine your first cryptocurrency. This crash course isn't gonna have all of the fluff you'd see in a normal publication. This is just everything you need to know to get up and running on your first cryptocurrency mining rig.

What is cryptocurrency mining?

One of the main things about cryptocurrencies is that they are "decentralized". Sounds great, but WTF does that even mean? Well, the easiest way to explain it is...
You know how if you want to send your friend/family money digitally, you can do so through your bank. Your bank likely takes a transaction fee and in a few days they will transfer the money. Since cryptocurrencies are decentralized, they don't have a bank or organization to fulfill the transfer of money. Instead, they outsource the computing power of their cryptocurrency network to miners (soon to be you). These miners are verifying transactions, securing the blockchain, and powering the cryptocurrency's specific network among other things. As an incentive, the miners collect transaction fees on the transactions that they verify and collect block rewards while new currency is still being introduced into the ecosystem.

What kind of rig should I build?

You can mine cryptocurrencies using your CPU, GPU, FPGA, or ASIC, but this is a GPU Mining subreddit, so I will cater this to GPUs.
For building a great all-around GPU rig, there are two models of GPUs that I'd recommend:
Both of these GPUs have solid hashrates across most mining algorithms and for a decent price! You should be able to find both of these kinds of GPUs used for around $200-$250 each, which is a great price if you know what happened during the last mining craze! ($200 GPUs were out of stock everywhere and people were reselling them for $600+ each)
There are also plenty of great AMD GPUs for mining, but I've worked mostly with Nvidia so that's why both of my recommendations are Nvidia and not AMD.
Other parts to your rig that you'll need are listed below. Most of these can be pieces of crap and are just needed to make the rig actually run, but the one spot you DON'T want to cheap out on is the power supply unit. A decent power supply unit will keep your home from burning down while also keeping your rigs up and running smoothly. Here are my recommendations:

She's built, now what?

Now you need to do a few things. I am a Windows miner, so I will be speaking to Windows here:
  1. Update Windows - Do all of the updates. Just do it.
  2. Update Drivers - Go to the EVGA website and download GeForce experience. It will keep your GPU drivers up to date.
  3. Go to Windows Device Manager and make sure all of your GPUs show up under "Display Adapters". If it is there, but it isn't showing the Name/Model of the GPU as the name, right click it and select "Update Driver". This should fix it.
Assuming you've done all of this, you're ready to download a mining application.

Mining Software

There are tons to choose from! Claymore, Phoenix, EWBF, LolMiner, etc... It can be overwhelming pretty quickly since they all have different algorithm support, speeds, efficiencies, and a whole lot more. On top of that, in order to get them running you need to set up batch files to call the proper exe, point you to the correct pool, and a whole bunch of other stuff that can be confusing to a new user. Not to mention, you will probably need a separate miner, config file, batch file, etc. for each different algorithm that you're interested in mining on.
Instead, I recommend that you download a miner management software that will take care of most of this tedious work for you. There are a few in the sidebar, but the /GPUMining favorite is AIOMiner. It was developed by our very own community member, xixspiderxix with the intention of making mining as easy as possible to do and without any fees. It supports over 100 different algorithms, so you'll be able to mine nearly ANY cryptocurrency you'd like. Just download it from their website and it will take you through a quick tutorial to help you get set up! You can also connect your rig to their website for remote monitoring and control. You've probably seen a few of their posts around this subreddit.
Other Windows mining softwares include:
Note: Many mining softwares have fees built into them. Most are around 1%, but can go as high as 5% or greater! You want a mining software with little or no fees at all so that you get to keep as much cryptocurrency as possible. These fees aren't something you actively pay, the software will automatically take it by mining on the developers behalf for a given amount of time and then switching back to mining on your own behalf. So, please be diligent in the software that you evaluate and make sure it is reputable.

I keep hearing about NiceHash. What is that?

The asshole of the mining industry. Jk, but not really.
NiceHash is a software program that allows you to sell your rig's hashing power to someone on their marketplace. They market themselves as profitable mining, but you're not really mining. You're selling your power in exchange for Bitcoin.
They did a great job telling people that with them, you're always mining the most profitable coin, but that's just not true. Since it is a mining marketplace, they make you mine whatever their most expensive contract is. If their contracts are below market prices, then you're not operating as efficiently and profitably as you could be.
NiceHash also has a sketchy history, which continues to this day. In 2017, they were hacked and lost $65M worth of Bitcoin. No one got paid out for MONTHS and many of their executives conveniently resigned. Their platform is also used to destroy cryptocurrencies. Since people are able to purchase mining power on their platform, people have used their platform to purchase enough mining power to control individual cryptocurrencies and duplicate coins, which increased the malicious user's wealth while completely destroying the integrity of the coin's blockchain. HoriZEN (formerly ZenCash), Ethereum Classic, and many other great cryptocurrencies have been the victim of NiceHash's platform.
For this and many other reasons, we highly recommend that you stay AWAY from Nicehash. We understand that it is extremely easy to use and you get paid in bitcoin, but they are destroying the industry with their greed and lack of motivation to change their platform for the protection of cryptocurrencies.

Concluding Thoughts

This is pretty much everything you need to know to get started. We covered the hardware, setting up the software, which software to use, and AIOMiner's tutorial will get you up to speed on how to actually mine the cryptocurrency that you want better than I can explain it, so I'll leave that part to them.
If you have any questions on this crash course, please leave a comment below where myself and other community members will be able to help you out.

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

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)

Profitable Crypto Mining: ASIC vs GPU, Which One Is Better?

Profitable Crypto Mining: ASIC vs GPU, Which One Is Better?
If you’re new to mining you probably have multiple questions running through your head right now. Good news is that it gets easier with time, assuming that you do your homework and research, and we will try to help you out.
One of the common questions is whether one should choose GPU or ASIC mining and we definitely have some advice on that topic.
When we’re considering classic POW mining we can quickly rule out CPU hardware for not being efficient and FPGA hardware because of its high costs. This leaves you with ASIC and GPU to choose from.

https://preview.redd.it/igev3y4v8pv31.png?width=1920&format=png&auto=webp&s=2a0c9271fc36252181d086e74101d13875619c80

Buying Mining Equipment

Let’s get things straight — you won’t be able to buy ASIC devices in any of you local electronic shops, even in the biggest ones. There are two ways you can get this hardware: buying it online which shouldn’t be a problem these days unless that’s the newest model you’re after. Second option is to find a local company that sells ASIC equipment.
Also, you can try to purchase the equipment directly from the manufacture company, however, mind the huge customs and delivery fees if the company is located abroad.
It is highly recommended to test ASICs before buying them to make sure the equipment works properly.
GPU or graphics cards and other equipment that you will need to build your very own mining farm can be easily purchased at a regular computer store. The only problem you may have is getting the right set of hardware, so make sure to come prepared.
When buying a used (second-hand) graphics card don’t forget to test it.
What’s better?
If you’re not into hardware and have no clue how to set up a farm by yourself buying ASIC equipment would be a better option as you won’t need to build anything yourself.

Warranty Policy

In general, an official warranty policy for ASIC hardware is up to 180 days since the equipment was shipped to the buyer. When the seller is confident about the quality of their equipment, they can offer their personal 1 month warranty.
When you’re buying computer hardware in most of the cases you are getting full 2 year warranty policy including exchange or repairments of the equipment.
What’s better?
Warranty policy is especially important when you have no chance to check the equipment yourself or when you’re buying large inventory of it. Also, if you plan to go with overclocking, you will probably need a decent warranty as well.
We need to add that when you’re using the equipment accordingly and conduct regular maintenance both ASIC and GPU can work past the warranty period.

Setting Up Process

With ASICs it’s simple: you plug and connect it, pick a pool to join and start mining right away.
With GPU, it’s a little complicated. First, you need to build your farm. You will need a framework, motherboard with installed CPU and cooling, storage unit, power supply, risers and video cards. If you have no experience with assembling computer hardware you’re gonna need to save some time and prepare to put extra effort. Once your rig is ready you will have to install OS and optimize it which is usually even harder than setting up a rig. But luckily we’ve got a solution for that. CoinFly can do the work for you and help you with setting up and optimizing your equipment.
What’s better?
Although ASICs are very easy, you shouldn’t quickly give up on GPU mining. If assembling computer hardware is not a big problem for you, CoinFly will help you with setting it up.

Maintenance

ASIC equipment won’t give you too much trouble: it’s safe, stable, and doesn’t require any special knowledge. Maintenance includes cleaning off dust and oiling the fans.
When dealing with rigs, you will have to work a little harder and study the basics about at least graphics cards’ temperatures and operational frequency. A stable workflow depends heavily on the software and as it has a tendency to fail, it could become a problem. Unless you’re using CoinFly — our system will notify you in case of emergency so you can tune your equipment online.
What’s better?
Once again, when it comes to maintaining ASICs are almost trouble-free. GPU rigs are a bit tricky but when using the right tools like CoinFly to monitor their work, it can serve you just fine.

The Noise

ASICs are loud: when you’re in a room with a working ASIC you’re gonna need to shout, so people can hear you.
GPU farms have no such problem. Some of them are almost silent and that doesn’t affect the cooling process at all.
What’s better?
Maybe the level of noise your equipment makes was not the first issue on your list but we recommend you to consider it. ASICs are suitable only for the commercial and industrial premises.

Mining

ASICs can work with only one algorithm and mine one or several types of cryptocurrencies and are perfect for mining Bitcoin and its forks.
GPU rigs are universal: you can mine a huge variety of coins if you set your miner right.
What’s better?
If you want to mine Bitcoin, you gotta go with ASIC. But think again if that’s what you’re really after. After all, you can choose mining any altcoin that you’d like with your GPU rig and then simply exchange it to BTC. And if you’re lucky enough to mine a coin that will do good ASICs do not give you that choice, however, their mining capability is higher.

Relevance of the Equipment

ASICs are quickly getting out of date as the new models come along. Back in the day, the new versions used to come out every half a year and they were 10 times more efficient. In general, you need to change your ASIC hardware every year.
GPU equipment can perfectly serve you for 2 to 3 years and if you wish to sell the graphics card afterwards that wouldn’t be a problem either.
What’s better?
In terms of relevance, it’s probably reasonable to go with the GPU.

Return on Investment

In the long run, the profitableness of ASICs is higher but because the new models are being released quite frequently you cannot expect huge profits. It is always important to do your research and get the most relevant equipment.
GPU hardware will take its time to pay you back but it also depends if you manage to find the right coin to mine that will eventually increase your profits.
What’s better?
ASIC mining is definitely a good option for those who don’t want to constantly monitor the crypto market.
But in the case that you’re interested in what’s happening in the crypto space and you also have time to do your own research, the GPU farm would the better choice. If you’re not willing to spend your efforts on that, CoinFly Autopilot mode will help you mine the most profitable coin on the market automatically.

Conclusion

ASICs are great for people who can provide a non-residential space for mining and not willing to spend too much time and effort for setting up the equipment and stay updated with the latest trends in the crypto industry.
GPU rigs are suitable for mining at home and won’t scare away all the crypto and computer enthusiasts. If you’re just starting your mining journey but not sure how to do it, we recommend to register on CoinFly. From setting up your hardware to tuning it online and picking the best coin to mine at the moment — we’ve got you covered!

Back to the Future: 2014 Bitcoin increase, market Crash, and GPUs flood the market.

Image a world, where Bitcoin hits a new ATH of 1,000 USD! A new coin emerged, Litecoin. Using a new Algorithm called SCRYPT which makes GPU mining profitable and a thing again!
The story starts in January 2014. AMD Just released it's newest GPU, the R9 290X in late Oct. this thing a monster of a GPU, extremely powerful! A GPU mining crazy has just hit the internet and waves of Tech people are making mining farms to mine Crypto. AMD GPU's are priced at premiums with 290's/290x's OOS or for sale upwards of $700, $200 over MSRP. Everyone is gulping up used AMD GPUs. Ebay is awash with GPUs selling over MRSP even used ones!
I was there, I started out mining Litecoin to Litecoinpool.org, I had 3 Rigs I slapped together in crate boxes. Mixature of 7970/7950/7850's and a single a 4 GPU R9 290x rig (over 1400w!!!) using AMD AM3+ Motherboards and CPU's running Windows 8. I even near the end had a 750ti Rig, the new Maxwell, efficiently mining SRCYPT. I'm glad i lived in WA at the time The electric bill wasn't bad at all maybe 200-300 a month. I lived in Ellensburg getting that sweet Wind farm Electric rate. I Remember this time as I struggling to learn mining, overclockings for mining, and rig stability. In the short period I did this February 2014 to May of 2014 I made 48 Litecoins. This was a fun period for me because I loved messing with the hardware and GPUs even made decent profits from selling used hardware because it became such a premium then. In the end I quit mining and sold all my hard around May/June. Then moved back to CA to live with my mom to help support her after she lost her job and couldn't find work. I sold off my entire small operation. In the end the Market crashed, MT GOX was hacked millions of Bitcoin lost, and SCRYPT ASICs were released. I stopped paying much attention to the crypto-sphere and just HODLed the small Bitcoin that I had traded from the Litecoin I earned. Bitcoin dropped down to $200 by the end of that year.
All in all I just want everyone to take in the fact that this exact, I repeat EXACT, thing has happened before in the long forgotten past of 2014. Yet everyone is making it out like its some crazy big deal? every crypto is still at high comparing to previous years, GPUs have declined in price because mining has died down, and ASICs are coming out for almost every Algo.
To those of you still mining, keep on my brother! If I had kept mining, or kept on eye on the crypto sphere rather than walking away like most are right now, I could mined Etherum back in the early days of 2015 and now could of been extremely well off. Now, that im in it again and this time with more foresight and readiness. I'm here to stay through this rough times. hopefully to come out to see the otherside. I Only started(again) in june 2017 so I was late for this "gold rush" but mark my words the massive "Gold rush" for crypto has yet to come...

ASIC water heater (Closed / Open Loop)

Edit 180517: Here's an article on motherboard.vice.com about this project. Thanks, Jordan! I enjoyed the read!
My ASIC waste heat recycling design is public domain and free to anyone who wants to use it. This turns any water-heating endeavor into a profitable, or at least cost-reduced, enterprise. Imagine a crypto heated swimming pool, or anything else you could heat with the output from a small, medium, or large-scale mining operation. This design should scale very well if you make the individual parts "bigger." Have fun!
Items used are a water / air intercooler off Ebay fed by 3/4" water hose and a Bosche 12v pump model #0392022002.
Attained water temperatures of 50C / 122F for a week before I took it down.
Closed loop. (Requires Underclock) https://i.imgur.com/l5goioK.jpg
Inside the box. https://i.imgur.com/QpG6dBe.jpg
Open loop (Can run 100%). https://i.imgur.com/kkgwDyr.jpg
The closed-loop is very quiet, the fans don't need to run anywhere near 100% with things underclocked. I ran mine around 30%, and while enclosed the sound is equivalent to a box fan on medium-ish.
The open-loop is good for winter, especially if you can duct it into your HVAC intake.
Both setups can be run in reverse to cool the intake air charge through the intercooler if a cold water source can be obtained. (Cold part of A/C unit dunked in coolant that is fed through the intercooler, for example.)
Edit 180516t1518z: Here is an example of the cooling loop that I have planned. Using this in conjunction with either prototype it should be possible to house any mining operation in any environment, so long as the cost of the cooling loop does not overwhelm the profits produced by the mining equipment. This is best suited to the open-loop configuration in conjunction with intake filters. If you live in the desert and have access to solar power, this may be for you.
Practical use scenarios for closed-loop:
Hot water for a bathtub / hot tub / swimming pool / shower.
Hot water for a radiator system to heat a residence.
Hot water to drive dishwashers / clothes washers.
Sous vide cooking, as pointed out by hazeldoo
Using this as a pre-heater for a boiler. (also could be used for commercial or industrial applications.)
Ex. of industries that user boilers are oil refineries, food canneries, paper mills, etc.
Practical use scenarios for open-loop:
Most of the applications above, plus...
Drying your hair.
Drying your clothes.
Diverting the hot air output into your HVAC to heat your residence as I did, this saved me $80/mo in pure cost during the winter.
Diverting the hot air / water to a single room to create a sauna.
I'm available for hire.

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.

Gagner de l'argent en se chauffant

Salut à tous,
Je viens d'avoir une idée, j'ai pensé qu'on pouvait amortir ses coûts de chauffage, en utilisant la chaleur des rigs de minage de cryptomonnaie.
Plutôt que de payer le chauffage et perdre tout le courant sous forme de chaleur, l'argent du chauffage permettrait de miner de la crypto avant d'être transformé en chaleur, ce qui permettrait d'amortir ou annuler les coûts de chauffage et gagner de l'argent
Il suffirait de dimensionner la puissance du rig en fonction des besoins nécessaires en chauffage du logement.
En faisant des recherches j'ai pu voir que je n'étais pas le seul à avoir pensé à ça : https://www.01net.com/actualites/ce-radiateur-mine-des-cryptomonnaies-pour-vous-chauffer-et-vous-faire-gagner-de-l-argent-1392200.html
J'ai même vu un mec qui chauffait l'eau de son bain avec son rig : https://motherboard.vice.com/en_us/article/9k8ykp/heating-water-with-bitcoin-mining-asic-reddit
Voilà voilà vous pensez quoi de tout ça ?

ASIC Water Heater (Closed / Open Loop)

Edit 180517: Here's an article on motherboard.vice.com about this project. Thanks, Jordan! I enjoyed the read!
Design is free to anyone who wants to use it. This turns any water-heating endeavor into a profitable, or at least cost-reduced, enterprise. Imagine a crypto heated swimming pool, or anything else you could heat with the output from a small, medium, or large-scale mining operation. This design should scale very well if you make the individual parts "bigger." Have fun!
Items used are a water / air intercooler off Ebay fed by 3/4" water hose and a Bosche 12v pump model #0392022002.
Attained water temperatures of 50C / 122F for a week before I took it down.
Closed loop. (Requires Underclock) https://i.imgur.com/l5goioK.jpg
Inside the box. https://i.imgur.com/QpG6dBe.jpg
Open loop (Can run 100%). https://i.imgur.com/kkgwDyr.jpg
The closed-loop is very quiet, the fans don't need to run anywhere near 100% with things underclocked. I ran mine around 30%, and while enclosed the sound is equivalent to a box fan on medium-ish.
The open-loop is good for winter, especially if you can duct it into your HVAC intake.
Both setups can be run in reverse to cool the intake air charge through the intercooler if a cold water source can be obtained. (Cold part of A/C unit dunked in coolant that is fed through the intercooler, for example.)
Edit 180516t1518z: Here is an example of the cooling loop that I have planned. Using this in conjunction with either prototype it should be possible to house any mining operation in any environment, so long as the cost of the cooling loop does not overwhelm the profits produced by the mining equipment. This is best suited to the open-loop configuration in conjunction with intake filters. If you live in the desert and have access to solar power, this may be for you.
Practical use scenarios for closed-loop:
Hot water for a bathtub / hot tub / swimming pool / shower.
Hot water for a radiator system to heat a residence.
Hot water to drive dishwashers / clothes washers.
Sous vide cooking, as pointed out by hazeldoo
Using this as a pre-heater for a boiler. (also could be used for commercial or industrial applications.)
Ex. of industries that user boilers are oil refineries, food canneries, paper mills, etc.
Practical use scenarios for open-loop:
Most of the applications above, plus...
Drying your hair.
Drying your clothes.
Diverting the hot air output into your HVAC to heat your residence as I did, this saved me $80/mo in pure cost during the winter.
Diverting the hot air / water to a single room to create a sauna.
I'm available for hire.

Heating Bath Water using Excess GPU Heat

Novel idea I just read, which circles back to a reddit post from gta3uzi about using his ASIC('s) as a water heater in his home. Exact same concept could be applied to GPU miners. Trade your Lambo's in for hot tubs, boys.

I have an idea for a Bitcoin mining powered desalinization plant.

Someone buy me.
C'mon, I'm cheap, easy, and my idea and I can be all yours for the low, low price of money.
Here's another thing I did once:

ASIC mining bitcoin vs GPU mining ethereum

Why does mining bitcoin with an ASIC antminer S9 appear much more profitable than mining Ethereum with 3 AMD GPU cards? This is per whattomine.com
I see antminer S9 going for $2,100 to mine bitcoin versus let's say about $1,500 to set up a 3 GPU rig for ethereum including cost of motherboard, monitor, etc.
The return on antminer with bitcoin appears far superior. Do the antminers become obsolete much quicker than GPUs hence higher risk? Or is there something else I am missing?

Magic internet money

Like a lot of people my coworkers and I have been discussing the cryptocurrency boom, and swapping stories we've heard. You know the ones:
I thought that one a coworker told me today would be a good fit for this subreddit. Overall story is the same as I was told, just anonymised and posted with permission.
Involved:
$CW = my current co-worker
$SmallCo – A smallish business with <15 employees.
$Bossman for the boss of a $SmallCo
$Old_IT for the old IT guy that used to work at $SmallCo
$CW was brought into $SmallCo on an emergency contract basis, apparently due to $Old_IT being terminated for “performance reasons” before $SmallCo could find a new permanent IT guy. $CW quickly found out through office gossip that the performance had to do with some inappropriate behaviour involving a young office admin and a lot of alcohol, and avoiding a lawsuit.
$CW was tasked by $Bossman to ensure that there was “no way they could get hacked by $Old_IT” ($Bossman was apparently a good dude with zero technical skills).
“While you’re at it” said $Bossman, “fix what’s making that godawful sound in the closet.”
$CW set to work securing what he could - ensuring that all passwords (including admin) were changed site-wide, dealing with vendors and suppliers to to let them know $Old_IT was no longer allowed to make changes, changed the entry codes for doors to offices and server rooms, and just general security practices you do when you terminate a SysAdmin. Then $CW started the hardware audit.
(At this point $CW paused in his story - he’d heard tales of SysAdmins who set up automated scripts that would nuke all systems if admin passwords were changed, but hadn't considered this before his updates. Thankfully, none of those malicious scripts were found, but he says he was sweating bullets when he remembered after changing everything.)
What $CW did find instead was
The works. It was heaven.
The servers in the “server room” (in reality a closet but with proper ventilation) were clearly labelled with the server name, IP, and with the purpose (DB server, mail server, etc) and all with pretty awesome cableporn worthy management.
It took $CW barely two hours to make sure all the hardware matched the documentation.
Except ... for this one machine in the server room. A big sucker, an extra wide base that looked out of place compared to the sleek machines in the room. The specific unit was the one that $Bossman had pointed out, and it was indeed making a terrible racket. No asset labels, no server information, no documentation, nothing indicating its purpose in the world other than to be noisy as hell. $CW tried plugging in keyboard and monitor but was unable to get anything he connected to respond, and no rogue IP on the network that could help him ID the purpose. No-one had any ideas what it did, so he performed a Scream Test.
Or at least he tried to - because he could not gracefully shut down (no monitokeyboard would work) he simply tried the old "press the power button for 10 seconds" (the IT equivalent of trying to smother it with a pillow).
When that didn’t work he said a small prayer, yanked the power cord from the back, and hoped that whatever happened to the machine it was not permanent. He then found that the networking for the unit did not run to the switches or business grade router for the office, but was plugged into a cunningly hidden (but consumer grade) second router, with the excellent cable management that matched the rest of the office.
The requisite 1 week period passed, and no screams. $CW found himself with little to do, so he took another look at this mystery machine. He tried plugging the power back in and powering it up, but there was only silence.
$CW, thinking he had killed this little server forever, obtained permission from $Bossman to open up the box and perform last rites. At the least he could pull the drive and work out what the system actually did, at worst he could cannabalise what he could and possibly build a new box for the business.
For those of you boys and girls paying attention, you’ve already guessed when $CW found, but I'm obviously thick and would never have guessed in a million years.
$CW found inside a box that was bereft of the normal computer or server gear you’d find in any kind of server - no Motherboard, no RAM, no drives, nothing but a power supply and some fans. Instead he found an older generation ASIC miner (I’ll leave you guys to google this yourselves for the full details, but short version is “Awesome Bitcoin Miner”) with the miner and the fans on the box the only things connected to the power supply.
The network cable ran into the box, and connected to the miner directly. All external buttons or connections on the tower proper were not actually connected to the internal workings. Power came from the wall to the power supply and straight to the miner. The only way to turn it on or off was inside the box itself.
$CW, being an honest person (much much more honest than I ever could be!), showed what he found $Bossman, explained what it was for, and advised to get the company lawyer involved, possibly the police just to be safe. $Bossman still didn't fully comprehend what was happening other than “$Old_IT was stealing electricity from $SmallCo”, but promised that at the end of that process, if $CW wanted the unit, he could have it.
$Bossman reckons the noisy server had been there for over a year.
$SmallCo found a new permanent IT guy soon after, because while $CW was good he was expensive (contractor rates) and other than the miner discovery $CW was bored. He still hasn’t heard back if he can get his hands on the miner yet, but last he heard $SmallCo was taking $Old_IT to court for the harassment and other items.
Considering how thorough $Old_IT was with everything else in the office, we're contending that he’d have backups of the crypto wallets in safe places, but it's still gotta hurt when you lose your job and your side income simultaneously.
TL;DR – Coworker found a strange box, filled with magical internet money!

A quick guide to GPUs and cryptocurrency.

There seems to be a lot of misinformation going on about cryptocurrency and how it ties into the new and used GPU markets. I want to try to help alleviate some of the false rumors as well as put together a quick resource to answer any questions someone may have. This is not to sway anyone to or away from crypto or anything like that. I just keep seeing threads that go something like this:
OP: GPU prices are so high right now C1: Oh it’s because of bitcoin OP: elaborate C1: bitcoin is mined 24/7 using huge GPU farms. The miners snap up any and every new GPU they find. OP: well I’ll just buy used! C1: bad choice jabroni. The miners run these cards so hot and heavy that they’ll instabreak as soon as you buy them. OP: oh well when will it stop? C1: bitcoin just crashed so we should see some new GPUs in stock soon OP: thanks dude!
This is an exaggerated exchange, but it is based on some of the more common things I see sometimes and it gets the point across. The fact is, a lot of people that comment are trying to be as helpful as possible, and that is absolutely a good thing. The problem comes when trying to water down the information to make it easier to comprehend for a beginner. That’s where I’m hoping this guide comes in. I’ll start off by explaining the process of mining as concisely as possible while still keeping all of the relevant information. After that, I’ll try to debunk/explain some of the myths surrounding mining and GPUs. Let’s hop in.
Mining in a nutshell:
Cryptocurrency mining is the act of using a cpu, GPU, or an ASIC (specially designed device) to solve mathematical equations that verify transactions. That’s a very general definition that we can work with. Within the general aspect of mining, there are different algorithms that are used for different currencies. Some currencies use the same algorithm, so you end up with more currencies than algos. Some algorithms are “ASIC-resistant”, so the best way to mine is with a GPU.
Now how do you actually get paid by mining? That’s simple. Generally speaking, any time any cryptocurrency is sent anywhere it must go through a verification process and will incur transaction fees. Who gets those fees? The same people that verify the transaction, miners. That simplifies the process a good bit, but it is still truthful.
That’s a good bit of background information. Let’s traverse a bit deeper and cover how somebody gets into mining. I’ll start by saying this: Hardly anybody mines Bitcoin. A little more emphasis for the people in the back. HARDLY ANYBODY MINES BITCOIN. Why is that? Because Bitcoin is not profitable unless you are using a high dollar ASIC. That is beyond the scope of this guide, so I’m not going to go there.
There are two ways for the Everyman to mine: choosing a coin and mining through a pool, or using what I call a “smart miner” like NiceHash. For the sake of simplicity, let’s use NiceHash from here on. NiceHash is mostly on par with the profitability of pool mining, and it is also a lot easier to set up. This simplicity is inviting to beginners and experts alike.
With NiceHash, you never actually mine coins for yourself. You sell your hashing power to those that are buying hashing power. You switch between whichever algorithm is most profitable and mine whatever coins the buyers are paying for, however, you are paid in bitcoin. Confusing? Cool, let’s get simpler. Say you have any amount of GPUs in a rig. In order to mine, download NiceHash, set up your account, and press the start button. Now you’re mining with power! In order to make this profitable enough, you’re going to want a rig with multiple GPUs. A common goal is 6-8 GPUs per motherboard w/ multiple motherboards.
So we’ve got all the background we need for now. Let’s tie in some market information. Currently almost all crypto currencies are down significantly, but that doesn’t change the fact that it’s incredibly volatile and could skyrocket in the next week. We have to deal with the fact that yes, crypto is down, but most people will continue mining because it will inevitably go back up. We may potentially see a drop off in miners buying cards until the return of investment goes back up. It’s kind of dismal right now.
Myth Madness:
M: Bitcoin is causing GPU prices to skyrocket.
E: Let’s replace a few words here. This is more accurate: “cryptocurrency is a big factor in the increase in GPU prices.” This is better, but still doesn’t tell the full story. While cryptocurrency is jacking up the demand for GPUs, a RAM shortage as well as the fact that manufacturers just can’t keep up is keeping supply down.
M: Miners snap up every available new card.
E: This one is pretty true, however, most miners aren’t just snapping up these cards at MSRP, they’re paying the same price everybody else would pay. In the market’s current state, the higher prices of GPUs hurt the return of investment especially when the dollar value of cryptocurrency is down.
M: Miners are only interested in AMD!/Nvidia!
E: this one is a common misconception. Some cards do outperform others, but that does not mean 6 rx 580s will outperform 6 gtx 1080s. Generally speaking, the most powerful card for gaming will be the best performer for mining. A 1080ti will earn around 6 USD per day while a 580 may earn 3 USD per day. Return of investment is actually pretty similar if you go by msrps. You pay more, you earn more to an extent. Most miners that are in it purely for profit are going for 1060 6gb and up, or 570 8gb and up.
M: Mining cards are run at full power 24/7 and are useless after they’re done with them.
E: The 24/7 part is true. Most rigs run constantly, but almost all miners undervolt their cards. The power consumption doesn’t do much to the hashrate, but it cuts into overall profit by drawing more electricity than it actually needs. In addition to this, heat is still an enemy as it is with a high performance gaming rig. To combat this, most rigs are in a cold room with as much airflow as possible in the form of multiple case fans, external box fans, ceiling fans, even portable AC units pointed directly at the cards. Miners are all about protecting their investments. The only wear that could be a problem is fan wear, which can be an easy fix.
M: This will pass when bitcoin crashes.
E: Cryptocurrency is in it for the long haul. 2017 was honestly the first year of widespread acceptance of crypto. It’s best to look at return of investment when talking about crypto and GPUs. With crypto down, GPUs won’t be bought as much. GPU prices go down, return of investment gets back to what it was. More GPUs are bought. It’s a huge ebb and flow type of thing.
Let’s go back to the original exchange from the beginning and see how someone could potentially answer the OP.
OP: GPU prices are so high right now. C1: unfortunately, we’re in a phase where manufacturers can’t keep up with the demand for them. OP: why’s the demand so high? C1: a big reason is cryptocurrency. Crypto miners are able to make a big profit off of mid-high end cards, so they buy them as fast as possible. Lower end cards are effected as well because gamers that can’t get the mid-high range are settling for low range to fit in their budget. OP: Well how about used? C1: If you’re getting a current gen Card, you should ask plenty of questions regarding the conditions it was in. Last Gen cards like a 970 or 980 are probably alright and will rival the performance of some 10 series cards. OP: What if I wait it out? C1: I wouldn’t advise waiting it out. It could take several months for this phase to pass. I would buy a 970 or 980 to hold over until prices even out.
That’s a lot more informed as well as being a lot more helpful to the OP. The best advice I can give if you want a high end card is to be vigilant about deals. Some places are offering GPUs at MSRP if you buy other components with it. That’s a great option if it’s your first build. All in all, we’re in a pretty troublesome time for PC building with the price of ram going up as well as the price of GPUs.
I don’t claim to be an expert so if there are any corrections or additions that need to be addressed, please let me know and I’ll fit them in.
