Why does bitcoin mine consume so much power
the power consumption of bitcoin mining machines is different according to different machines take Shenma 68T, the fastest mining machine in wet season, as an example. Suppose that the electricity charge is 0.22 per kilowatt hour in half a year in wet season and 0.34 per kilowatt hour in dry season, the wall power consumption of Shenma 68T's second-hand machine is 3264w, and the actual power consumption is 3500W, then the daily power consumption of a Shenma M20S 68T machine is 3.524 = 84 degrees, Annual power consumption 84 * 365 = 30660 degrees
according to the latest mining difficulty, a Shenma 68T machine can dig 0.00064836 BTC a day, and 10 machines can dig 2.366514 coins a year. The mining difficulty of the premise remains unchanged, but according to the current situation, it is assumed that the mining difficulty will increase by 30% from now to next June, and by 2.5% every month. It is estimated that 85% of the original coins should be g, that is, 2.012 coins. Ten machines of Shenma 68T can dig almost 2 coins a year
to sum up, the power consumption of ten Shenma 68T machines in a year is 306600 kwh, which can dig almost two coins

the risk of mining machine
1. Hardware expenditure
< P > mining is actually a competition of performance and equipment. Some mining machines are composed of more such graphics card arrays. With tens or even hundreds of graphics cards, the hardware price and other costs are very high, There is considerable expenditure in miningin addition to the display card burning machines, some ASIC (application specific integrated circuit) professional mining machines are also put into the battlefield. ASIC is specially designed for hash operation, and the computing power is quite strong. Moreover, because their power consumption is far lower than that of the display card, they are easier to form scale, and the power cost is also lower. It is difficult for single chip display to compete with these mining machines, This kind of machine costs more
2. Currency security
the withdrawal of bitcoin requires hundreds of keys, and most people will record this long string of numbers on the computer, but the frequent problems such as hard disk damage will make the key permanently lost, which also leads to the loss of bitcoin
3. System risk
system risk is very common in bitcoin, and the most common one is bifurcation. Bifurcation will lead to a drop in currency price and a sharp drop in mining income. However, many cases show that the forking will benefit the miners, and the forked competitive currency also needs the miners' computing power to complete the minting and trading process. In order to win more miners, the competitive currency will provide more block rewards and handling charges to attract miners. Risk makes miners

bitcoin is an electronic currency proced by open-source P2P software. Digital currency is a kind of network virtual currency. Bitcoin is also paraphrased as "bitcoin.". Bitcoin does not rely on specific currency institutions to issue, it is generated through a large number of calculations of specific algorithms. Bitcoin economy uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions. The decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin through mass proction.
because his algorithm determines that the later the algorithm is, the greater the amount of computation, and the greater the power consumption
the first group of people who g up mines, because it was easy to dig out coins and the currency value was not high, a hamburger needed thousands of coins
now, however, he has been given too many concepts. Global demand has been triggered. Supply is far less than demand, which has triggered a mining boom. The price of RMB is also linked with the mining cost
in view of the increasing cost of mining, the price of RMB is also higher and higher
the power of computing machines is also increasing, which consumes a lot of energy. Many places restrict this kind of "invalid" power consumption, which shows that it accounts for a large proportion
this kind of global game is really very difficult and the cost is not small.
