Free electricity for mining machinery
the other is the purchase cost of mining machinery hardware, which is a one-time expenditure
so if there is free electricity, it is worth mining
I hope it can help you. If you think it is useful, welcome to adopt it!
Every 100 S4 bitcoin mining machines consume 900W of electricity per hour
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

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
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
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
