5 Best Bitcoin Mining Hardware ASIC Machines (2020 Rigs)

Bitmain has released a "limited" batch of S17 for the bargain-bin price of $3799, BEFORE shipping, and BEFORE taxes

" Lol. I love how Bitmain prices each unit 36 percent the mass of a Bitcoin, or 800 percent the mass of a "B**coin Cash"... 12 months before the scheduled supply halving. You're 100 percent more in the profit acquiring the Bitcoin itself, at market cost, and riding it out the lifecycle of a Bitcoin miner, about 24 months. Bitmain will get competitive with their pricing when their competitors arbitrage the ASIC supply chain. I'll wait for "3nm" chipsets and below to get back into mining, maybe in 2024... Or when an ASIC costs 1 percent the mass of a Bitcoin, not 36... Lol... Oh Bitmain... The good news is, that there is some airhead that WILL buy these ASICs, at this price, and wreck themselves, right before the most epic bull run in BTC history, so ironically they'll be better positioned to reap the benefits of an ASIC. Pricing is just sad. Nothing proud to be about. "

I got hammered on other /r/'s for defending XMR anti-ASIC upgrade!

With the network hash finally settling at a 75% reduction the XMR April 6th protocol upgrade was a RAVING success for all of us. Again hat's off to the DEV Team. I'm such big fan I posted the following post and got hammered. Comments like "What about the other 99,990 people that own ASICs!" Really? There has not been one Cryptonight ASIC sold to the public that I know of... man-o-man there's a lot of people there living in a small world. Did I do wrong with the post below? You tell me???!!!

I'm not sure how many of you out there on this forum are "miners" or even care--but this is important.
Decentralization is the heart and soul of the crypto movement. Centralization means anyone or thing--typically a "government" in command or control. Well for the Crypto space it looks like there a lot more to it than what meets the eye.
The entire crypto movement is enabled by "mining" which are the computing processes that run the networks. Way back when that was "individuals" using their own PCs to keep Bitcoin (and now all the other coins) well--an individual statement.
ASICs are specialized chipsets that basically just "mine". They are very efficient and extremely fast. As much as 100x faster than a PC with a GPU card. Massive farms have sprung up by industrial backers to extract profits. I'm ok with free markets--and that is the way it goes. BUT--no one really knew how much or how many "ASICs" were out there... well now we know. Monero just recently changed the algo for mining the network on April 6th. The entire amount of global computing power on the network has been reduced by 80%--EIGHTY PERCENT. So whether it is government(s) or large scale industrial actors--there remains a war on the individual.
Huge hats' off to the Monero Dev team for fighting for the little guy. If you are not aware about mining and the tremendous contribution it makes to all things crypto I would encourage you to learn more....
I would encourage everyone in the Cryptospace to fight for decentralization--because in the end it does affect you.
If you are ASIC Farm, well, looks like you just got punched in the nose by the little guy!

My Experience: From FX-8350 to R7-1700

Upgrading from an FX-8350 to a R7-1700.
Just a bit about me – I have been building computers since the mid 80’s. I missed the 8-inch floppy disk era, but came on board when dual 5.25” was considered mainstream and a 10-megabyte full-height HDD was the mark of a power user. The first computer I built for my own enjoyment was an AMD X5-133 (a factory overclocked 486 faster than the Pentium-75), and I’ve used a wide variety of systems since then, including a Pentium Pro-200 which served me well in college and a K6-2 which I took to quite a few LAN parties. While I’ve always had Intel notebooks, my PC’s have been AMD for quite some time now. I decided to upgrade my current main machine, which is an FX-8350 with a mild 4.4Ghz overclock. I was using 2x8GB Crucial Ballistix DDR3-1600 and a Sapphire Radeon Fury Nitro. While I know the R5-1600x would be a better bet for a pure gaming build, I have a soft spot for 8-core machines. I had been tempted to pull the trigger on an i7-7700k for a while, but the timing never worked out. But when I found the R7-1700 at a deep discount and an X370 motherboard on the shelf next to it – I couldn’t resist the siren call of a new build.
Here are my thoughts about the process:
AM4 is physically the same as AM3 from a build perspective, except for the mounting holes. I don’t know what was so important about making the holes have different offsets, but this makes it much more difficult to get quality cooling. Not all manufacturers have brackets yet, and I’m still waiting on Cooler Master to release the brackets for my Siedon 240.
The new motherboard feels very different from my AM3 board. My FX-8350 sat on an ASUS M5A99FX Pro R2.0. It was, for lack of a better word, a very workstation-ish board. 4 PCIx16 slots, 10x USB ports (2 of the USB 3.0), triple USB 2.0 front panel headers (and a USB 3.0 front panel header as well), eSATA on the rear panel, beefy VRM and Northbridge cooling, Toslink output for audio, and so on. The board itself is full of tiny components, support chips, and ports. Granted, many of these connectors are outdated (eSATA and USB2.0), and the PCIe is only 2.0 instead of current-gen 3.0, but there is a LOT of connectivity. Few people paired an FX chip with triple of quad-GPU for gaming, but I know a fair number of people used these for bitcoin mining back before there was widespread ASIC support and back then GPU mining was the most cost-effective way to mint cryptocurrency. Extra PCIe slots could be used for dedicated video capture, PCI-based storage, a RAID card, etc... Having 4 full-size slots allows this kind of flexibility. The new motherboard is an Asrock Fatal1ty x370 Gaming K4. It does not feel very workstation-ish at all. It has only two 16x PCIe slots (and when they are both in use they are only 8x), 8 USB ports on the rear panel, and a much less “busy” motherboard. Very few support chips litter its surface. Instead of a workstation component, it feels much more like a luxury consumer product. This is not a bad thing – just something I noticed while building the system. The rear IO shield is red and black to match its gaming aesthetic, it includes things like premium audio (including a very nice headphone amplifier for the front panel connectors), and while it only has 8x USB ports on the back, 6 of them are USB 3.0 and two of them (including a type-C connector) are USB 3.1 gen2. It includes RGB LED’s under the chipset heatsink and three separate RGB LED controller ports (one of which is used for the boxed cooler), Intel gigabit Ethernet, and dual M.2 slots (one of which connected directly to the CPU). It is very different in “feel” from the older ASUS board, even down to things like a shroud for the external connectors and metal-reinforced PCI slots. I must say, its more aggressive appearance and near-empty areas appeal to me. It does, however, funnel the builder into a particular configuration: limited fast storage through the M.2 slots, slow(er) storage through the 6x SATA ports, all external devices should be USB 3. Personally, these limitations didn’t restrict me for this build, since that was how I was going to set it up anyway, but the fewer connectivity choices might cause some pause for others. The only thing I don’t like about this board is the 20 second POST times. 20 seconds every time. Resuming from sleep is very fast, just reboots are slow. That’s really it. I have no substantive complaints other than that – well, and the memory speed limitations – more on that below.
The Wraith Spire cooler is without doubt the best looking box cooler I’ve ever seen. The symmetrical cylinder look, combined with the LED logo and RGB ring are very striking. I can see why many people have asked to order one, though I think for the 1700X and 1800X they are better off without it. I’ll explain why further down.
Initial hardware setup was very easy. I was able to flash to the newest 2.0 BIOS without any hassle using a DOS USB flash boot drive. The 2.0 BIOS has the newest AGESA code from AMD, as well as support for the R5 processors and better DDR4 compatibility. I didn’t want to cheap out on RAM since apparently Ryzen is sensitive to DDR4 speeds for the latency between cores. I bought the cheapest 16GB DDR4-3200 kit I could find (the EVGA SuperSC 2x8GB), for which I paid $115. While I was not able to get it to boot at 3200, I could get 2933 simply by activating XMP, then manually changing the speed from 3200 to 3000. I then tested it with MemTest86 for two complete cycles, which it passed without errors. I have encountered zero memory issues with these RAM sticks running at 2933. Since this motherboard does not officially support DDR4-3200 at all, I figure this is a good outcome. I am curious to know whether anyone has gotten 3200 on this board – that is, whether the lack of 3200 memory on Asrock’s QVL is a marketing issue or an actual hardware limitation – but I didn’t want to spend nearly double that amount in order to get AM4 verified memory (G.Skill’s FlareX), and 2966 seemed fast enough from the benchmark results I had read.
My old setup had a Samsung 850 EVO 256gb SATA6 drive as the primary boot/gaming drive. It seemed plenty fast but it had become too small for my needs, so this seemed like a good opportunity to buy a new SSD. I originally thought the NVMe drives would be out of my price range, but I bought the Intel 600p 512GB drive for only $10 more than I would have paid for a premium SATA6 drive. Though the 600p is without doubt the SLOWEST NVMe drive out there, it has 3x the read speed as the SATA6 drives, and most of what I am doing with it is trying to get quicker load times. If I was using it for professional workloads (as a video editing scratch drive, for example), I would need much higher sustained write speeds and then Samsung would be the obvious answer. I just didn’t want to spend an extra $80 on write performance that I’d never notice, and the 600p has been an excellent boot/gaming drive.
Ok, back to the Wraith Spire. I tend to have bad luck with the silicon lottery. My FX-8350 was not able to be stable above 4.4Ghz with reasonable temperatures. I was hoping I would be able to get better results from the R7-1700, since general reports indicated that it overclocked well. Unfortunately, it is difficult to tell how good of an overclock I am getting since I can find no good information about maximum recommended temperatures for this chip. Some people say 75c is the maximum safe temp. Others say 75c is a fine everyday 24/7 temp. Others say they are running it at 80c all the time without any issues at all. Steve at Techspot was getting 88c and 90c when overclocking the 1600X and 1500X using the stock coolers and without any instability – were those dangerous temps or totally fine? Nobody seems to know. I like my overclocks to be set-and-forget. I want to get it dialed in and then leave it for years without worrying that it will burn up or degrade or that in this or that application I have to turn back to stock speeds because of the thermals. Since I don’t know what max safe thermals are, I just have to guess based on stock thermals.
For stock speeds, the Wraith Spire does a good job. It is very quiet, and after a few BIOS fan-curve tweaks, it keeps the chip around 35-38 at idle, and around 68-70 on Prime95 (Small FFT, for maximum temperature generation). Incidentally, it also hits 70 if I run Cinebench a bunch of times in a row as well, so I don’t consider the Small FFT test to be totally unrealistic for the load this chip might encounter. From what I can tell, these are good normal temps. I can get 3.5Ghz by simply changing the multiplier and leaving the voltage at stock. This gives Cinebench numbers around the 1550 mark (roughly 6900k levels). Prime95 shows a modest boost in temperatures of 3-4 degrees C, and was stable even for several hours. If I push it to 3.6Ghz at stock voltage the system is unstable. At 3.7Ghz (the 1700’s boost speed for single-threaded loads) it is stable only if I give it 1.3v. While that is a totally fine voltage (AMD recommends up to 1.35v for 24/7), the Wraith Spire cannot handle a Prime95 Small FFT load anymore. I shut down the test and reverted the OC when the CPU read 89c. Given the fact that the Spire was meant to cool a 65w chip (and so probably is rated at no more than 85-95w), this is not a terribly surprising temperature – I wish I knew if it was dangerous. I have no doubt that a 240mm radiator or even a decent tower cooler will be more than enough to cool down my 3.7Ghz R7-1700. I am a little jealous of the people who just set the multiplier to 3700 and are good to go – lower voltages probably mean the Spire would be enough. But for me, it was not to be. I was halfway tempted to see at what temperature the chip would reduce its clock speed, but I didn’t want to burn up a chip I had just bought – might as well wait until I get bigger and better cooling to OC it to the 3.8-3.9 I hope it will reach.
Other than the OC temps it has been smooth sailing. Gaming feels more fluid than with the FX, even in games that I always thought were GPU-limited and/or running at 60fps with VSYNC on. Especially games that are sensitive to single-core performance (Heroes of the Storm is my latest addiction) there is a definite boost in 1% low and 0.1% low FPS. I have been using the Ryzen Balanced power plan from AMD and it seems to do a fantastic job keeping temps low when idle and letting the cores ramp up really fast when needed. I need to test whether the lack of core parking prevents it from hitting the 3.7Ghz boost as much as the regular Balanced plan allows. I think a simple CineBench single-thread comparison will do the trick.
I also tried streaming a bit – and it was able to generate 1080p60fps at x264-medium settings without being noticeable while in game. Later I edited some video of my kids – the final render speed was SOOOO fast. I am, on the whole, very happy with my upgrade. I get better single-core performance, much much better multi-core performance, along with faster disk speeds, and a more modern platform (with RGB lighting, M.2, USB 3.1, etc…).
Now if only I could find out appropriate temperatures…..

Updated FAQs for newcomers

TL:DR: Don't bother mining if you want to get rich yo. You're way too late to the party.
Welcome to the exciting and often stressful world of bitcoin! You are wondering what looks like a once in a lifetime opportunity to get rich quick. Of course you guys probably heard about this "mining" process but what is this?
Simply put, a bitcoin mining machine that performs complicated calculations and when deemed correct by the network, receives a block which contains 25 bitcoins (XBT). This is how bitcoins are generated. So your brain instantly thinks, "Holy shit, how can I get on this gold rush?"
Before you proceed further, I would like to explain the concept of mining further. Bitcoin is limited 21m in circulation. It is coded to release a certain number of blocks at a certain time frame, ie: this year the network will release close to 500,000 bitcoins. What this means is that the more people (or specifically the amount of mining power) mine, the less each person gets. The network tries to keep to this time frame through the process of difficulty adjustments which makes the calculations harder and this happens every 2 weeks. So every 2 weeks, you get less bitcoins with the same hash rate (mining power) based on what the difficulty changes are. Recently, the changes have been pretty staggering, jumping 226% in 2 months. You can see the difficulty changes here.
Now, why are these changes so large?
A bit of a simple history. Bitcoin's algorithm runs on SHA-256. This algorithm can be solved using many hardware, from CPU to GPU and dedicated hardware (Application Specific Integrated Circuits). When bitcoin first started, mining on CPU was a trivial process, you can pretty much earn 50 XBT (the block size then) every few hours between Q1 and Q2 of 2010.
In late 2010, due to the difficulty increase that is reducing the effectiveness of CPU mining, people started to harness GPU mining. Only AMD GPU's architecture design are better optimized for bitcoin mining so this is what the community used. Immediate improvements of more than 10x was not uncommon.
In time of course, GPUs reached their limit and people started to build dedicated. In the same vein as the CPU to GPU transition, similar performance increase was common. These ASICs can only perform SHA-256 calculation so they can be highly optimized. Their performance mainly depends on the die size of the chips exactly like CPU chips.
In general, think of bitcoin mining's technological advancement no different to mining gold. Gold panning (CPUs) vs pickaxes (GPUs) vs machinery (ASICs) and we are still in the ASIC mining race.
ASIC mining started with ASICMiner and Avalon being first to the market, both producing 130nm and 110nm chips. The technology are antiquated in comparison to CPUs and GPUs which are now 22nm with 14nm slated for Q1 next year by Intel but they are cheap to manufacture and with performance gains similar to the CPU to GPU transition, they were highly successful and popular for early adopters. At that point in time since there were less competing manufacturers and the low batch runs of their products, miners became really rich due to the slow increase in difficulty.
The good days came to an end mid August with an unprecedented 35% increase in difficulty. This is due to existing manufacturers selling more hardware and many other players coming onto the market with better hardware (smaller die). Since die shrinking knowledge and manufacturing process are well known along with a large technological gap (110nm vs 22nm), you get an arms race. Current ASIC makers are closing in on our technological limit and until everyone catches up, the difficulty jumps will be high because it is just too easy to get a performance increase. Most newer products run at 28nm and most chips are not well optimized, so it will be around another 6 to 9 months before we see hit a hard plateau with 22nm or 14nm chips. The estimated time frame is because manufacturing chips at 22nm or 14nm is a more difficult and expensive task. In the meantime most manufacturers will probably settle at 28nm and we will reach a soft plateau in about 3 months.
Now, you might ask these questions and should have them answered and if you have not thought about them at all, then you probably should not touch bitcoin until you understand cause you are highly unprepared and probably lose lots of money.
No. If you have to ask, please do not touch bitcoin yet. You will spend more on electricity cost than mining any substantial bitcoin. Seriously. At all. A 7990 would produce a pitiful 0.02879 XBT (USD $14 @ $500/XBT exchange rate) for the next 30 days starting 23 Nov 2013 at 35% difficulty increase.
And if you think you can mine on your laptop either on a CPU or GPU, you are probably going to melt it before you even get 0.01 XBT.
Probably not because you probably forgot that GPUs and CPUs produce a ton of heat and noise. You can try but I see no point earning < $20 bucks per month.
No, because your machine will probably not mine as much as buying bitcoins. This situation is called the opportunity cost. While you can still make money if XBT rise in value, it is a fallacy.
IE: if you start mining on 1 Dec 2013, a KnC Jupiter running at 450Gh/sec (KnC lies as not all chips run at 550Gh/sec) will yield you a total revenue of 9.5189 XBT with a profit of 0.7859 XBT in profit by 30th Jan 2014 at a constant difficulty increase of 35%. The opportunity cost is: 8.5910 XBT @ USD $580/XBT with USD $5,000 which is the cost of a KnC Jupiter. This is the best you can earn and it's a bloody optimistic assumption because:
The only circumstances where you will earn money is when XBT exchange rates is so high that it makes the opportunity cost pales in comparison. Unfortunately this is not the case. If XBT stabilized at 900/XBT today (20 Nov 2013) then we might have a good case.
The risk is just generally not worth it. Unless you have at least a hundred thousand and can make a contract with a manufacturer for a lower cost, do not bother. Just wait until the arms race is over then you can start mining.
Okay, go buy an AsicMiner USB Block Erupter. They are cheap and pretty fun to have.
Sure, just read the answer below on who NOT to go for. You are doing bitcoin a service by securing the network and you have our (the users') gratitude.
You can check out the manufacturers and their products below along with a calculator here.
If you still insist on buying, do not to go for BFL. Their track record is horrid and borderline scammish. KnC fucked up a lot with defective boards and chips. Personally, I think CoinTerra is the best choice.
Alternatively, you can go on the secondary market to buy a delivered product. You can get a better deal there if you know how to do your "return on investment (ROI)" calculation. Personally, I will go for a 45%-50% difficulty increase for the next 3 months for my calculations and a 2% pool fee.
However, most products on ebay are sold at a cost much higher than it should. bitcointalk.org is a cheaper place because everyone knows what are the true value is so you will find less options. If you are unclear or need assistance, please post a question.
I actually do not use any of the pools recommended to the left because I think they lack features.
My favourite is Bitminter (Variable fees based on features used; max 2%). It has all advanced features for a pool, very responsive and helpful owner on IRC. Variable fees is good for those who do not need a large feature set, even with all features turned on, it is still cheap.
Eligius (0% fees) has high value for money but lacks features. It has anonymous mining which might be attractive to certain subset of people but not for others. Many other community member and I disagree highly with the opinions of the owner on the direction of bitcoin. I do use his pool for now but I do so only because I share my miners with a few partners and anonymous mining allows us to monitor the machines without using an account. Bitminter uses only OpenID which is problematic for me.
BTC Guild (3% fees) is another big pool and is fully featured and does charge a premium for their fees. That said, they are the most stable of the lot. I do use them but do so only because my hoster uses them for monitoring. I try not to use them because a pool with a very large hash rate (they are the largest) presents a large vulnerability to bitcoin's network if compromised.
All of them pay out transaction fees.

GPUs will make a comeback to mining, and in doing so, will destroy the security of the Bitcoin network

The reason why Bitcoin is relatively secure right now is because the cost to mine is extraordinarily expensive.
Why is it so expensive? Not because of the cost of the silicon, or even really the cost to manufacture, but because the only use of an ASIC is for mining SHA-256 cryptocurrencies such as Bitcoin. When people pay up to $15,000 for an ASIC miner, they're paying for all the time and effort that went into it.
But consider this: What if mining machines become multi-purpose? In particular, what if GPUs return to the fore as competitive mining machines?
Now I know what you're thinking; you're thinking 'You fool, GPUs will never come close to the efficiency of an ASIC'. But the thing is, they don't need to be. They only need to be cheap, since the purchase cost of an ASIC greatly outweighs its electricity cost.
A 'CoinTerra AIRE' ASIC slated for release in March this year will cost $2499 and do 4500 GH/s. Now taking into account a number of factors like electricity cost and rate of value depreciation, I'd estimate that for a $200 GPU to be competative, it needs to do about 225GH/s - an improvement of 375x on current hardware. Impossible you say? Well, the hash rate of nVidia GPUs has improved by ~70-80x in just a few years, without any intentional focus towards Bitcoin: 5.66 MH/s 8600GT to ~414 MH/s GTX 960.
The nVidia GTX 780ti is a top of the line card currently priced at $440 and it does 0.5 GH/s, yet an Ati 280X which costs just half the price does at least 0.7 GH/s.
Ati cards have always displayed better performance in mining, but why? I'm no expert on the technical details, so I'll only say what can be deduced and is relevant: GPU designs can be altered to increase efficiency/performance when it comes to Bitcoin mining - this is a proven fact from the Ati/nVidia difference!
So far, these chipset makers have no doubt been focused on improving gaming performance. But what if they realize that there are many people who will buy more of their GPUs if they have the added benefit of good mining performance, as in 2011? Surely it wouldn't be too difficult or expensive to rearrange things a bit or slap a few things on - If a bunch of amateurs can create ASICs, how difficult could it be for a multi-billion dollar company to improve the hash rate of their GPUs at minimal extra end cost to the consumer? Or what if gaming just naturally tends more towards GPUs having better hash rates?
When this happens, Bitcoin will have a security crisis on its hands. There are millions of people with mid or high level graphics cards. In Q1 2014, AMD and NVidia sold a combined 14 million add-in boards. But let's be conservative - let's use the publically available Steam data, which says that yesterday there were a peak 8.3 million concurrent users online. Steam's hardware survey says about 65% of these are not mid or high level cards, so 0.35 x 8.3 mil = 2,905,000 people with decent AMD or nVidia cards who are conscious users (i.e. not office workers) at a certain time of day. For those 2.905 million gamers to launch a concerted and sucessful 51% attack on the network, their GPUs would only need to do on average 57.14 GH/s. If $200 GPUs were to be doing 225 GH/s, the entire number of ASICs throughout the world would be no match!
If you want a 'tl;dr' then go listen to Fenton or Shrem egg you on to buy or something - stay in your little dreamland while the price falls like a rock

Cryoniks, Inc. - Lets Talk FrostBit^TM

Dear "everyone",
First of all, we'd like to thank the reddit community for reaching out to us to help clear up a few misconceptions and hopefully answer a few of the questions that seem to be causing a lot of confusion; we sincerely apologize for any inconveniences our launch may have caused - it was definitely not our intention. We'd also like to apologize to the editors and talented staff at TechCrunch for the negativity they were exposed to on our account. We're deeply sorry and extremely appreciative of the opportunity they so kindly granted us. Also, please pardon in-advance the length of this post - we have a lot of questions to answer!
Instead of taking a defensive approach, we thought we might take this time to share a few key features of our tech that has rightfully (unintentionally) provoked or confused quite a large number of people - we should have addressed these questions directly on our site and we deeply apologize.
The FrostBitTM Bitmining Solution does in fact generate liquid nitrogen. This feat is accomplished in 3 steps:
This three-phase cycle is continuously looped during functioning operation taking full advantage of the already pre-chilled conditions of expended liquid nitrogen. A thermally insulating foam is injected into every unit after assembly to help minimize heat-exchange during this looping process. A lot of people were curious as to why we would use a thermally insulating foam on a compressor; it has the wonderful added benefit of dampening sound levels within the unit aside from keeping everything nice and insulated.
Another key feature of our unit is our custom-designed ASIC processors designed to run at much lower temperatures. Though we have not yet made the "processor" operating temperatures public, we will divulge however that we use a slightly modified EB lithographic process to manufacture our chips using select high-temperature superconductive materials. Our fabrication process is very similar to current processes used in the production of high-grade CMOS sensors and chipsets. The advantages are three-fold: less energy consumption, higher clock-rates, and most importantly; minimal heat exchange.
As a material nears or reaches the point of superconductivity, electrical resistance within the material reaches a sweet-spot of "almost-zero" resistance. This phenomenon is well documented and enables our ASIC processors to release less heat and run at much faster and energy efficient operating conditions than typical ASIC processors (chipsets for those cringing at the word processors). Less energy is wasted while achieving much higher cycle-times. We have coined our designs the ASIC+ Cryonic ArchitectureTM
Typical processors found in high-end home PC's and GPU's do benefit greatly from low-temperature operating conditions. These however contain materials that are not designed to undergo cryonic operating conditions and will fail at eventually at material-specific temperatures. ASIC processors currently on the market also suffer from this phenomenon and are useless in a cryonic environment.
A lot of criticism has been dealt over our elected use of the customizable light-strips. We understand the this may have been slightly misleading on our behalf - our light-strips are designed to run under 2.2W of power on the highest setting. We employ a similar technology to those found on e-Reader devices to disperse light "on the surface" making maximum use of the available visible LED light produced. (Not sure about everyone else but we really love our light-strips!)
Additionally, heavy criticism for a service yet-to-be announced will now officially be clarified (again, our sincerest apologies for not making this abundantly more clear on our website ; the FrostBitTM 3D upgrade will require software and hardware modifications. We strive to take our technology to higher levels of scalability and thought our customers might appreciate the option to modify their already pricy units to do various other resource-intensive tasks. As the vast-majority of the unit expense is in providing the unique cooling system, we wanted to offer pre-existing customers a cost-effective solution to attain the same stunning results our Bitcoin configurations achieve and apply them to other domains that will benefit from our cooling technology. Additional updates as to this upgrade will be officially posted when available.
With respect to power consumption and required power infrastructure; we feel confident that consumers are well-aware that pre-existing infrastructure already exists to power many-a-household appliance in-use by the majority of our target demographic; if you can power an electric stove-top or a washing machine, you're already covered. Additional information may be found with the provided User Manual and the Safety & Maintenance Guide provided with every purchase.
Thank you to everyone that has shown us support over the last few days - we sincerely appreciate it and hope to surpass your expectations by continuing to provide you with unique products designed to run smarter, cleaner, and with unparalleled performance (and look good doing it too!). And though we can't morally call out any of our "competitors" for their obvious mishaps and false-promises - we humbly request that we be given the opportunity to establish our presence and gain your collective trust by delivering on our promises promptly and transparently unlike the many disappointments that have sadly, come before us.
If anyone has any additional questions, concerns, requests, or would like more information; kindly drop us a line at your convenience by visiting us at cryoniks.com and contacting Support.
Thank you all, it's been an absolute pleasure; Chris Whiting - Lead Project Manager, BitFrostTM
