Output of eight pieces of 230 Suanli miner

180 coins

invest 200 coins, 230 coins can be settled in a round of two months, 1380-1200 = 180 coins can be settled in six rounds of a year, and 200 coins can be g in 52.5 days to rent a miner

you can rent one in 44.5 days for the second one, 29 days for the third one, 21 days for the fourth one, 13.5 days for the fifth one, 5.5 days for the sixth one, and you can pay 200 yuan for two for the seventh one

extended data

using time superposition 153.5 days to earn 200 coins, two medium-sized mining machines run in parallel, the next 26.5 days can settle 200 coins, three medium-sized mining machines run in parallel. In the next 17.5 days, 200 yuan can be settled, and in 8.5 days, six small mines and eight minicomputers can be fully loaded, with a total of 208 days

for the remaining five months, the net income will be 126.8 yuan according to three rounds of calculation (126.8 yuan for four small mines and eight minicomputers) × 3 = 380.4 coins

mining machinery seed 936 + 380.4 = 1316.4 coins, a year later, the most conservative estimate of the value of a coin is 700 one coin

700 × 1316.4＝921480

when building bitcoin, Nakamoto wants bitcoin to be a decentralized currency, not only for use and trading, but also for mining. But it backfired. With the increasing value of cryptocurrency such as bitcoin, mining has become an instry. The competition is more and more fierce, and the pursuit of mining computing power is higher and higher. Therefore, from ordinary computer mining, ASIC mining machine and GPU mining machine have evolved

the algorithm of ASIC mining machine is almost sha256, while the algorithm of GPU mining is different. For example, the algorithm of BTG is equihash, and the algorithm of BCD is optimized x13. Although it is not absolute, it can be simply considered that the currency of sha256 algorithm is generally mined by ASIC mining machine. Other algorithms are basically using GPU miner. There are also exceptions. Scrypt's Leyte coin used to be mined by GPU miner, but later scrypt's algorithm was also conquered by ASIC chips, such as ant miner L3 +, which is the ASIC miner used to dig Leyte coin

ASIC miner refers to the miner that uses ASIC chip as the core of computing power. ASIC is the abbreviation of application specific integrated circuit, which is a kind of electronic circuit (chip) specially designed for a specific purpose. Some mining machinery factories have designed ASIC chips specially for computing the sha256 algorithm of bitcoin, and the mining machinery using them is ASIC mining machinery. Because ASIC chip is only built for specific computing, its efficiency can be much higher than that of CPU. For example, the current mainstream ant miner S9 is ASIC miner, which uses 189 ASIC chips, the computing power reaches 13.5th/s, and the power consumption is only 1350W. As a comparison, the computing power of gtx1080ti, the flagship computer graphics card, will not exceed 60mh / s even if it is optimized well. The difference is tens of thousands of times

the purpose of GPU miner is to make money, so we should pursue the power consumption ratio and maximum profit, so we should pay attention to the cost performance. Generally, the medium and high-end positioning graphics cards, such as AMD rx560 and rx570, have high power consumption ratio, which is a good choice for GPU miner. While flagship cards such as gtx1080ti and AMD vega64 have the strongest single card performance, they are not cost-effective in terms of price and power consumption

in addition, the ASIC miner also has some exotic procts, such as the USB miner of burning cat, which is slightly larger than the U disk, and the power consumption is only 2.25w, which is the smallest bitcoin miner at present
