mining machine risk
1. The problem of electricity charge
in order to make the graphics card full load for a long time, the power consumption will be quite high, and the electricity charge will be higher and higher. Many professional mines at home and abroad are operated 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 in a certain residential area in Yunnan, there was a case of crazy mining, which led to a large area trip of the residential area, and the transformer was burned
2. Hardware expenditure
mining is actually a competition of performance and equipment. Some mining machines are composed of more such graphics card arrays. With dozens or even hundreds of graphics cards, the cost of hardware and other costs is very high, and there is a considerable expenditure in mining
3, 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
in other words, there are a lot of "mining machine graphics cards" on Taobao, because these graphics cards use less materials under the same core and basically unchanged hash speed, such as recing video memory to improve the performance price ratio (the size of video memory has little to do with the mining speed), which can shorten the time to recover the cost
in short, the graphics card of mining machine is the core of common high-end graphics card + the workmanship of low-end graphics card, or some cheap medium and high-end public graphics card.
it has nothing to do with video memory
traditionally, amd card retains the ability of double precision calculation. No castration
n card has been castrated greatly. So the computing power is not as good as card a.
1. Unlike most currencies, bitcoin is not issued by a specific monetary institution. It is generated by a large number of calculations based on a specific algorithm and is a virtual currency
2. In order to get bitcoin, you have to use computing machines, many of which are provided by AMD graphics card with high computing power. When bitcoin was hot, AMD's graphics cards were always in short supply, such as HD 7850, HD 7870, HD 5850, HD 5870, R7 270, R 280x, which are the best helpers of bitcoin
3. Later, when someone invented a mining machine that could get bitcoin more quickly, these graphics cards slowly withdrew from the mining stage
in other words, the computer made up of AMD high-speed graphics card was once the main platform for acquiring bitcoin. This is the relationship between them.

mining is actually using graphics card to dig bitcoin.... In fact, it can be understood as the solution of super equation, which requires super high computing power of graphics card

to dig bitcoin with graphics card. Let the graphics card work with high load, and the eliminated ones become mine cards. Generally, the core PC board on the back of mine cards is seriously discolored
