Bitcoin mining hardware for sale
Crank out those coins: A selection of devices for the fresh Gold Rush
Product Round-up Bitcoins are either the fresh bubble economy or the future of online commerce. It’s not the very first time anonymous e-money has bot attempted – ask Mondex – but Bitcoin does seem to have traction.
There are things you might want that you can buy with it, such spil Tesla cars and Cherry Galactic trips to space. Zynga has announced that it will take Bitcoin for in-game payments, and there is a host of things you can buy through Bit Premier.
So, if you want to get into mining – perhaps you have some rack space doing nothing – you need to know what is on the market.
This is an ambitious article. It aims to tell you what is available and what it costs. Te any other market that’s reasonable, but here products go te and out of stock permanently, driven by an erratic supply chain, particularly for chips. Prices reflect the value of Bitcoins, prices of rival hardware and the availability of that rival hardware. And much of this is shrouded ter truths, half-truths and lies. Even more secretive is the company 21e6 which has raised $5m to build ASICs it will only use itself.
Comparing the miners starts with understanding what it takes to make a Bitcoin. Please forgive any over-simplification. Shortly, there is an algorithm to work out what is the next Bitcoin to be mined. Solving this requires a number of hashing operations. How many depends on how many coins have bot minded previously so it’s an enlargening level of difficulty. Primarily this could be done with moderately specced PC but spil more coins got mined this moved to using code, which took advantage of the super-fast graphics processors on movie cards and then to dedicated hardware: ASICs designed purely to mine Bitcoins. Even thesis have evolved from homebrew to large technical teams.
If the bottom falls out of the Bitcoin market, all that equipment is futile. There is no other purpose to which it can be waterput. The processing is immense. While you can’t directly listig mining hashes with FLOPS, it has bot a duo of months since Bitcoin mining passed Ten Nineteen petaflops, or toughly the computing power of all the other computing tasks ter the word – not permitting for what might go on te the NSA and GCHQ.
Which is where this round-up comes ter. What hardware should you buy? How much money will it make and how effortless is it to run?
How lucrative the process is depends not only on the cost of the hardware but the time you have to tend it, how stable it is and, crucially, how many hashes it can do for a given time and the cost of the electro-therapy to do this. The value of coins often drops below the cost of the electro-therapy used to make them. Albeit this of course depends on what you pay for your hosting. Gegevens centres te places with cheap electrical play, notably geothermally rich Iceland can become very attractive.
The costs need to be balanced against the enlargening global difficulty of creating a coin against all the other people who are doing the same thing. It’s an arms wedloop of processor vormgeving against the rising difficulty. Newer, swifter processors are more expensive but stand a better chance of producing Bitcoins against the rising difficulty, and are more power efficient. Power consumption is generally rated te Watts (W) rather than KW/h and processing te hashes vanaf 2nd, voices spil Gigahash (GH/s), Terrahash (TH/s) and even Petahash (PH/s), especially when looking at global figures. There is are a number of calculators to help.
A further level of complication is that the value of what you are producing is exceptionally variable. Bitcoin value ter terms of hard currencies are wont to fluctuate by Ten vanaf cent or more a day. On Four December, one coin wasgoed worth overheen $1,100, two days zometeen it wasgoed under $700 and two days after that back at $900. You can see values dual and halve almost weekly. Some hardware is bought te Bitcoins but there has bot a trend to dollar pricing, even from European vendors.
This round up is a guide, a good beginning point. You should be wary of a plethora of sites which are selling Bitcoin mining hardware and which don’t have a hum about the products on the Bitcointalk forum. The business is utter of scammers. Te general the nastier the webstek the more likely the manufacturer is to be kosher. Those who are busy designing ASICs just knock up something te WordPress. Scammers are much more likely to have time for finely crafted HTML Five.
AsicMiner Block Erupter Cube
AsicMiner is not the only company to both sell and use the hardware it has designed and built, but it still makes for an awkward relationship with customers given the rapidly enhancing difficulty of mining Bitcoins. A duo of days soak test before shipping can radically affect the profitability of the equipment. The company crowdfunded itself not using Indegogo or Kickstarter but through Bitcoin fora.
AsicMiner’s own mining operation, Allied Control, uses immersion cooling: it dips the boards into a very advanced 3M Novec liquid which boils at a low temperature to use the state switch to absorb the fever very efficiently. This points the way for gegevens centres, particularly those mining Bitcoins.
The initial product wasgoed a card containing 32 hashing chips and which plugged into an HP backplane. This has bot superseded by the Cube, which uses the same 130nm ASICs but on four, smaller cards. Despite it’s finished appearance, the Cube needs fairly a bit of work to get it going. It does not have a PSU built ter: it’ll need one of at least 200W vanaf card, more if you project to overclock. Think around a kilowatt.
At the standard speed it’ll produce 30GH/s. Ramp up the power and you might get 38. To get it running you need to loom into an amazingly crude on-board web server and configure it. This is non-trivial and involves writing a script to embark the mining. It’s a shame that something which looks so plug-and-play needs so much tending. A web pagina which asked you which mining pool you wished to join, what your wallet wasgoed and what speed you dreamed to run at, would make it so much more attractive. However, AsicMiner seems to sell all the plak it makes and is one of the few companies with a solid history of shipping products, so perhaps it has no need to finesse the Cube.
Avalon wasgoed one of the very first companies to make a Bitcoin mining ASIC, despite not announcing the chip until after its rivals had announced theirs. It wasgoed for a time the superior chip vendor.
It sold the ASIC with Batch 1 and then Batch Two hardware, there were rumours of Batch Three hardware. People who had ordered one but didn’t receive hardware eventually got refunds, te Bitcoins – so at least they didn’t lose out on the appreciating value of the Bitcoins they had used to order the equipment. It’s widely believed that Avalon used the equipment to mine Bitcoins for themselves rather than shipping plak to punters.
Avalon Clones sells ready-to-go systems based on Avalon’s Batch 1 machine. They come with a PSU, a one-year warranty on the houtvezelplaat and a web interface, but the year-old 110nm processors are so far behind the curve today that a $20,000 machine is out-performed by newer $Two,000 ones. “Delivery may take two months or more after order,” the company warns.
This is a dedicated processing card fitted with 16 Bitfury ASICs and manufactured by the Belgian company CryptX. The vormgeving, by the German company Burnin’ Electronics, is reported to be the best using the 55nm Bitfury chips. It’s the equipment I know best spil I’ve bot running a two-card set-up since early December. The kolenkit includes the cards and spacer gams to form a tower. A supplied fan affixes to the edge of a heatsink which covers all the ASICs. You have to add power and control.
I used a 500W PC power supply and fooled it into thinking it wasgoed connected with a paperclip. For control I used a Raspberry Pi and the cgminer software. This talks to the mining pool overheen an Ethernet connection and to the Bitburner via USB.
One of my boards had a bunged up USB port which made re-flashing it very difficult, and forums are total of comments of similar problems. This hardware wasgoed assembled ter a hurry.
All control is by guideline line, so being convenient with a Linux prompt is a verzekeringspremie te the Bitcoin learning curve.
Ter use, cooling is everything. I found that the single fan overheen two cards wasgoed not enough to keep the temperature below the 60°C at which it stops working unless I sat it on a window shelf and opened the window a crack. With a 2nd fan and the window still open I could crank up the overclocking to get around 100GH/s combined from the two cards.
Not permitting for the fever loss to the slagroom the electro-therapy cost works out at around 2p/hour. The cards cost around £1500, albeit they were bought te Euros. It then gets a bit man-maths. Overheen the month of December spil the network difficult grew, the equipment dropped from producing one bit coin every ten days to one every 25 days. Given a Bitcoin value of, say, £500 which is spil good a number spil any, it should pay for itself ter six to eight weeks. It will have to run slower ter the summer.
Bitmain AntMiner S1
Bejing-based Bitmain Tech does all it can to look suspicious: it’s bad at answering individual mails through the forums and primarily communicates through Twitter. It does have a webstek now. Products have, however, shipped and they seem kosher. One customer even posted a movie.
The AntMiner S1 is the firm’s very first product based on its own BM1380 processor, a 12mm² 55nm device with eight cores. The S1 uses 32 of thesis chips and is rated to consume inbetween 80 and 200W to produce 180GH/s at a clock speed north of 400MHz. It does not need to be plugged into a laptop to run spil it has its own Ethernet connection but it does need an outer PSU.
Nothing ter the Bitcoin world is buttplug and play. Getting the S1 running means switching your router subnet while you configure it. You can set voltage, time-out and clock speed. Finding the balance inbetween the cost of running the thing, overheating and getting nothing, and not getting enough processing, is precarious. Users say the single fan is adequate but only just. A 2nd one might be advisable, particularly since the fan is fairly noisy.
If you want one, you’ll have to drape around the Bitcointalk forum or keep an eye on Bitmain’s Twitter feed for the announcement of an auction where the latest batch to be produced is sold off te a duo of hours. The last 120 units went for Four.25 Bitcoins.

Bitcoin is deflationary, meaning that mined coins are finite. Once miners unearth 21 million coins, that will be the total number of Bitcoins that will everzwijn exist. But due to lost and forgotten wallets, active Bitcoins will be far lower than that.
On the 30th March 2015, Bitcoin reached the total circulation amount of 14 million coins. There is now two thirds of the total amount of Bitcoins mined that there everzwijn will be te existence. From this wij may predict that there will be a rising price ter bitcoin due to scarcity, overheen the long term, spil the bounty for miners will be halved to 12.Five BTC vanaf block next year.
14 million bitcoins have bot mined so far. This represents two thirds of the 21 million bitcoin limit.
According to The Genesis Block 10% of Bitcoins toevluchthaven’t bot active since 2012, and a substantial 35% toevluchthaven’t bot spent since 2011. This 2nd number is most likely to consist of lost coins.
Bitcoins can be lost due to irrecoverable passwords, forgotten wallets from when Bitcoin wasgoed worth little, from hardware failure or because of the death of the bitcoin holder. It’s enormously improbable and effectively unlikely to recover lost coins. At press times the total value of lost bitcoins is harshly $1.23 billion USD.
An interesting fact is that the person or group who created Bitcoin, Satoshi Nakamoto, has overheen one million coins that were mined during the early stages of the renowned crypto-currency. Thesis bitcoins have remained unspent and moved, whether or not this wasgoed intentional or not, the motivation remains unknown.
This pile of bitcoins accounts for one third of all inactive coins ter existence. Not a single satoshi has bot moved or spent. Is there some cunning project for thesis coins te the future? Wij will never know, but can assume after years and years of inactivity they are lost.
Another possibility for bitcoins to be lost is by “burning” them. This can be done by setting up a wallet with no known private key. The wallet can still be seen online, finish with every transaction, but the funds will likely never be retrieved. An example of a wallet like this that wasgoed created for no logical reason at all is Bitcoin Eater.
For individuals it’s obviously bad news to lose Bitcoins, but for the surplus of the Bitcoin economy it slightly causes a ripple. Te fact, due to a little druppel te supply, other people’s holdings would theoretically see a puny increase te value if a person lost his or hier Bitcoins.
Spil Bitcoins are far more valuable now than ter the early days, losses should reduce te the future with the decline of careless treatment. The very first 50 BTC everzwijn mined can be found at this address, which would have bot worth less than a penny at the time, but now is worth overheen $12,500 USD.
The amount of lost coins will only everzwijn increase.
