Mining second hand graphics card

1.

Generally, there are professional graphics cards to mine, and the mine is actually bitcoin. Users download the mining software from the computer and then run a specific algorithm. After communicating with the remote server, they can get the corresponding bitcoin. Most of them work by burning the graphics card, so the power consumption is large

the graphics cards and mine cards are usually ATI chips. The bitcoin market is not good, so the miners take out their mining cards and sell them as second-hand

what is mining

to put it simply, mining is to use the chip to perform a calculation related to the random number, and get the answer in exchange for a virtual coin. virtual currency can be exchanged for the currency of each country through some way. The stronger the computing power, the faster the chip can find this random answer. Theoretically, the more virtual coins can be proced per unit time. Because it's about random numbers, you can only get rewards if you happen to find the answer. It's possible that one chip will find the answer in the next second, or ten chips won't find the answer in a week. The more chips compute at the same time, the easier it is to find the answer, and the mining machine with built-in multi chips appears. And a number of mining machines to form a "mine" at the same time mining is to improve efficiency. In the mine pool, multiple "self-employed" join an organization to mine together. No matter who finds the answer and digs out the virtual coin, everyone gets the corresponding reward according to the calculation ability of contribution. This way can make the income of "self-employed" more stable

relationship between mining and graphics card

the stronger the computing power of ant miner, the easier it is to dig out virtual coins. Accordingly, when the more virtual coins are g out, the difficulty of mining will be increased accordingly, so as to control the yield of virtual coins. The virtual currency is not unlimited. The total number of bitcoin is 84 million

Mining graphics card is an excessive loss of the life of the graphics card

how long it can be used depends on the processing materials of the graphics card and how long it has been mining

it is recommended to choose the graphics card, and you can choose a brand new one in tmall or jd.com, which is more secure

3. You can buy a power contract or lease a miner for mining, or you can buy your own miner and place it in the custody of Chinese and foreign mining companies for mining.

4. Mining and CPU has nothing to do with the speed of the GPU, the more stream processors, the faster the graphics card digging. HD5830 7950 is the first choice. You have to worry about the electricity bill

5. Mining is generally hd7870 and hd7990, other mining is not enough to see

6. You can't do this with two graphics cards. In the special effects will occasionally card

7850 is worth buying, mine card? Generally, it doesn't have to be so low-end

7. Mine cards are sold as second-hand, which is something JS likes to do most. And mine card is also a favorite of some machine manufacturers.
