Determining Electrical Cost of Bitcoin Mining

This wasgoed written ter response to a chunk written by Tim Fernholz about miners spending $17 million a day for a slok at $Four.Four million of bitcoin. I do recommend reading his article on international money smuggling.

Spil wasteful spil it sounds to spend $17 million a day to build up $Four.Four million, this article is based on false gegevens. Mining Bitcoins may use a boat blast of violet wand, but there are profitable miners out there unlike Tim’s article claims.

The gegevens used te the article is from blockchain.informatie, a company near and dear to my heart, that provides a nice spread of Bitcoin services like wallet management &, coin mixing services, block informatie, a well designed pagina for Bitcoin public addresses, and several charts and stats to help folks digest the sophisticated and stijlvol solution to financial freedom that is Bitcoin.

It just so happens that Tim choose the most inaccurate lump of gegevens on blockchain.informatie and I’ll illustrate why te just a 2nd.

Bitcoin miners’ tens unit use is fairly high and miners don’t think twice about it. Well they begin to reconsider when their profits are guzzled by violet wand costs. And react by either selling their miners to fresh Bitcoin users who have caught the Bitcoin mining bug or determine to repurpose their miners for the very speculative market of mining Altcoins.

The surplus of the informatie I present will vertoning how truth is often ter error when summarized by statistics and boiled down to one number. Here are some tables I whipped up displaying the range of miners available to Bitcoin users with ASIC miners.

I’ve compiled a brief list of miners from companies who have or voorwaarde to have miners on inventory. They have bot seen ter the wild and mining joyfully while Bitcoin enthusiasts around the world cheer them on or yell at them for not just buying Bitcoins with their money.

The very first problem is assuming all miners use 650 Watts vanaf gigahash. The nature of ASIC vormgeving is to manufacture more efficient ASIC overheen time enlargening hashing power and use less violet wand with each iteration. One year, a 65nm ASIC miner may very well draw 650 Watts, but the next generations of ASIC miners will get more efficient and could draw 550 Watts. This pagina of stats, to my skill, hasn’t bot updated to reflect the latest miners that have come online ter the past year.

Mining Company Released Miner Name Total Watts Used Miner Type ASIC width KNCminer Jupiter1 550 Watts Sha256 28 nm Butterfly Labs MiniRig 2400 Watts Sha256 65 nm Avalon Four Module 750 Watts Sha256 65 nm ASICminer USB Block Eruptor .Five Watts Sha256 65 nm Blockchain.informatie assumption n/a 650 Watts vanaf gigahash n/a n/a

Table 1: I used http://mining.thegenesisblock.com/ for the miner information. The shipping dates and availability on this webpagina is out of date, but the list of companies is comprehensive.

Here’s another table that shows the range of residential violet wand rates ter the United States and around the world [sources 1 Two].

Location Tens unit Rate (cents vanaf kilaWattHour) US, Westelijk South Central Ten.91 US, South Atlantic 11.81 US, Fresh England 17.Four US, Pacific Noncontiguous 29.04 India 8 China 8 France Nineteen Australia 29 Spain 30 Denmark 41

Table Two: Sample of International Electrical Costs within the past Two years.

Denmark has a peculiar situation where households pay far more than the average business for electric current based on this published gegevens which is based te Euros.

The 2nd problem is the blockchain.info’s stat pegs the average electrical use to $0.15 vanaf kilowatt. The table listing the electrical costs for various regions of the world clearly shows a miner’s location should be considered even before thinking about a miner. Certain towns have large corporations absorbing the lion’s share of the electrical costs. Others may use solar power or gas generators.

Here’s yet another table displaying the gegevens from the very first table with the worst case screenplay of the 2nd table comparing the profitability of a miner ter Denmark if they were to use any of the miners available right now.

Released Miner Name Total Watts Used Electro-therapy Cost for a Denmark Miner overheen 1 month Estimated Monthly earnings with a 1 billion difficulty2 Jupiter 550 Watts $162.36, €118.02 7.8 BTC, $6856, €4972.80 MiniRig 2400 Watts $708.48, €515.00 7.Two BTC, $6317, €4581.85 Four Module 750 Watts $221.40, €160.94 1.29 BTC, $1132, €821.06 USB Block Eruptor 0.Five Watts $0.15, €0.11 .0048 BTC, $Four.211, €3.05 blockchain.info’s estimate 650 Watts vanaf gigahash $191.88, €139.48 Miners Monthly earnings >, 0.2191 BTC to profit.

Table Three: Combination of Table 1 and Two

I found out the estimated profits by logging on to https://webchat.freenode.netwerk/#and te the #kncminer channel is a bot called elwizbot. This bot is something special spil it is the most accurate estimate and rekenmachine of Bitcoin earnings vanaf day and hour. I have no clue who wrote this bot or how it makes its calculations, but spil each difficulty switches, its estimates based on the earnings from users on that irc talk and on KnCMiner forums are pretty accurate.

If you send elwizbot a certain instruction, it will give you estimated Bitcoin earnings.

<,throwaway_acct>, >bc,genghestimate 550<,elwizbot>, The expected generation output, at 550 Ghps, given estimate upcoming difficulty of 1037702886.49098228 , is 0.266552987625 BTC vanaf day and 0.0111063744844 BTC vanaf hour.

The last table shows that even ter Denmark, a miner could pay off their ridiculously high electrical bill and afford to save Bitcoins at the same time. This profit is strenuously dependant on price, but with the current prices crossing the $1,000 mark passed twice this year (presently lower now!), several miners have made enough to pay for their miner based on the accounts of some miners.

Even with the true cost being somewhat better than what is reported at blockchain.informatie, I don’t advocate going out and grabbing a miner (or paying for the promise of a future miner) this late te the spel. I do hope anyone ter the market for a miner would consider more than 1 statistic on 1 webpagina. At least verify theBitcoin community’s results at the Bitcointalk mining forum and hear what others have said about their Bitcoin mining practice with miners and mining companies. It is significant to know how reliable a company is, since some have gone bankrupt, have unrealistic delivery schedules, or encounter delays due to the complexity of manufacturing cutting edge ASIC technology.

Another argument against purchasing ASIC mining technology is the concept behind the difficulty of the Bitcoin network. The difficulty looks at the average time it takes to process a block from the blockchain and if it is under Ten minutes the difficulty goes up. If the time is overheen Ten minutes the difficulty drops. Spil the Bitcoin network grows the blocks will be processed quicker and almost ensure an increase ter difficulty that makes it firmer and tighter to squeeze out Bitcoin mining prizes.

A more interesting topic would be to explore where the average miner gets their electrical play. Looking past electrical companies and into how their violet wand is generated, whether it be from combustible fuels, nuclear, hydroelectric, geothermal, wind, or solar this would be a far more fruitful discussion to determine whether miners are feeding into the kinky (nuclear power) or nice (mining with solar power) ways of getting power to verify Bitcoin transactions.

1) I realize Jupiter is presently out of stock, but used this miner spil an example of the most efficient miner. Theoretically this miner could be purchased 2nd arm.

Two) I also realize comparing the earnings overheen 1 month with a difficulty that adjusts every 2016 blocks or every 10-12 days is very futile. This is why I used the upcoming difficulty which will be around 1 billion and not the current difficulty of around 900 million.
