How much electricity is consumed by bitcoin mining
bitcoin mining machine is a kind of computer used to earn bitcoin. This kind of computer generally has professional mining chips and works in the way of burning graphics card, which consumes a lot of power. It is one of the ways to get bitcoin that users download software from personal computer and then run specific algorithm to get corresponding bitcoin after communicating with remote server
the popular digital currencies in 2013 include bitcoin, Leyte coin, zeta coin, pennies (Internet), invisible gold bar, red coin, pole coin, barbecue coin and prime currency. At present, hundreds of digital currencies are issued all over the world
the price of bitcoin mining machine ranges from two or three hundred yuan to 200000 yuan. From 2011 to 2013, high configuration bitcoin & quot; Mining machine & quot; From 10000 yuan to 300000 yuan, but the performance is much better than before. According to instry insiders, the old machine can only dig 1 bitcoin in 100 days, but now (2013) machine can dig 3.5 bitcoins in 100 days
according to the miner information published by the domestic assembly team, a miner with the lowest configuration at the price of 3000 yuan can be returned in more than 30 days according to the bitcoin mining speed. The machine with mining speed of 10G / s can dig about 0.03 bitcoins 24 hours a day, while the machine with mining speed of 13g / s can dig about 0.035 bitcoins 24 hours a day according to the computing power and difficulty of the whole network in 2013.
Taking t2t-30t as an example, the calculation force of t2t-30t is 30t, and the power consumption is 2200W, that is, 2.2kW. The power consumption of a single miner in 24-hour operation is 2.2kW * 24 = 52.8kwh, and the electricity charge is once calculated as 0.56rmb, the daily power consumption cost of a single miner is 52.8kw * 0.56 = 29.57rmb
to "mine" with bitcoin mining machine, if the graphics card is fully loaded for a long time, the power consumption will be quite high, and the electricity bill will be higher and higher. There are many professional mines at home and abroad in areas with extremely low electricity charges, such as hydropower stations, while more users can only mine at home or in ordinary mines, so the electricity charges are not cheap. Even some people in a residential area in Yunnan carried out crazy mining, which led to a large area trip of the residential area, and the transformer was burned
extended data
mining principle of bitcoin mining machine:
bitcoin mining and node software mainly initiates zero knowledge proof and verification transactions through point-to-point network, digital signature and interactive proof system. Each network node carries out broadcast transactions to the network. After these broadcast transactions are verified by miners (computers on the network), miners can use their own work proof results to express confirmation. The confirmed transactions will be packaged into data blocks, and the data blocks will form a continuous data block chain
every node of bitcoin will collect all the unconfirmed transactions and gather them into a data block. The miner node will add a random adjustment number and calculate the sha256 hash value of the previous data block. The mining node keeps trying again and again until the random adjustment number it finds makes the hash value lower than a specific target
take an ant s9-13.5t mining machine as an example, the power is 1.35kw
the power consumption of 24 hours a day is: 1.35kw * 24h = 32.4kw/day
according to your local electricity charge, assuming that the electricity charge is 0.5 yuan / kWh, 32.4 * 0.5 = 16.2 yuan / day
then an ant s9-13.5t mining machine can consume 32.4 kwh a day, The daily electricity charge is 16.2 yuan

Bitcoin is one of the most popular virtual currencies, which is very popular on the Internet
recently, according to the bitcoin power consumption index released by Cambridge researchers, if bitcoin is regarded as a country, it will rank among the top 30 countries with the largest power consumption in the world. The annual power consumption of bitcoin mining is about 121.36 terawatt hours (TWH, 1 terawatt hour is 1 billion kwh){ RRRRR}
recently, Bill Gates made it clear that he is not a fan of bitcoin
Bill Gates said: & lt; Bitcoin consumes more power per transaction than any other way known to mankind, so it's definitely a very important climate issue. But if it uses green power, it may not be a problem in the end
I don't think these topics are deeply relevant, although you may label me as a bitcoin skeptic
in other words, instead of investing in bitcoin, I used the money to buy malaria vaccines. I invest in companies that make real procts. But if other people invest in bitcoin and make money, I'll congratulate them& rdquo;
Bitcoin is very power consuming and its value fluctuates greatly, which is similar to a speculative investment
To get bitcoin by mining requires a lot of power< p> What we need to know is that at present, the mainstream mines use graphics cards to improve the computing power of mining. Each miner has several graphics cards, and each miner has several miners. In this case, the power consumption is naturally high. But the point is that as long as anyone who has followed bitcoin news knows about it, even if bitcoin ranks among the world's top 30 power consumers, it will only surprise everyone, not particularly strange. Especially in the current bitcoin hot situation, more and more people are engaged in the mining instry, and it is expected that the power consumption will naturally increase
with the further spread of this kind of virtual currency, dog money has graally come into people's sight, and more and more people want to invest in this kind of virtual currency. Because some very rich people will invest in this kind of virtual currency. For example, musk is keen on investing in dog money. In any case, there are a lot of people who can make huge profits
