Low power of Shenma mining machine
in addition, according to people familiar with the matter, after Yang Zuoxing was investigated, Shenma mining machinery did not appoint a new CEO. Instead, the company's operation was jointly maintained by people in charge of various fields. Some customers who bought futures sought a refund because they were worried about the Yang Zuoxing case. The okex intelligence agency has also written about Yang Zuoxing's enmity and entanglement with Bitai mainland before, "Yang Zuoxing was arrested for 100000 yuan," god horse "fell to earth to become" native horse ", Here's a brief introction to the background of the news: it is understood that Yang Zuoxing was a chip engineer of bitcontinental before, but he didn't discuss with janketuan, the founder of bitcontinental in 2016 e to the equity issue. Yang Zuoxing therefore left bitmainland, and later founded bitmicro, and launched Shenma mining machine. Shenma mining machinery has leapt to the top three in the instry with a rare speed since its establishment. According to people familiar with the matter, Shenma mining machinery is the mining machinery giant next only to bitmainland, accounting for about 40% of the market share. But since then, Yang Zuoxing and the mainland have been in the dispute of related cases.
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
for example, the power of an ant V9 mining machine 4T is 1.05kW, 20kW can drive 19 mining machines
the power of an ant T9 + miner is 1.45kw, 20kW can take 13
the power of a Shenma mining machine is 2.1kw, 20kW can take 9 sets
according to the different power of mining machines, the number of mining machines that can be carried is also different

many free electricity miners use m3 and pay back in two months
50 cents per kilowatt hour miners use m3, and their daily income is not enough to pay the electricity bill.
your three-phase 10kW motor current is generally about 20A, The power factor is not as simple as you think. It's very complicated to calculate. Here I will tell you that it's 20 A. if there is a single-phase load, the current is larger than 45 A. It can be taken as 60 A.
it is recommended to use a 100A three-phase meter, which is 3 * 100
