Bitcoin mine closes graphics card

1.

Why use graphics card to mine

compared with CPU, GPU is used for general purpose calculation. So it can stack hundreds of stream processors awesome. Each stream processor is like a small CPU. Although its ability to run complex programs is far from the power of CPU, it can not support many processors, so the actual performance, especially the single precision floating point performance is much stronger than that of CPU. p> However, as we have mentioned before, a card is very suitable for general computing such as virtual currency because it has many stream processors, and the speed of obtaining specific solutions is much higher than that of N card. Therefore, many miners rush to buy a card to calculate virtual currency for profit

of course, with NVIDIA's Pascal graphics card, n card's ability in mining virtual currency is not as different as a card before. So in the current situation that a card is generally out of stock, those mid-range N cards have become the second choice for miners

What are the disadvantages of mine card

finally, I want to talk about why we can't choose mine card when we are shopping for second-hand cards. Because the miners are mining bitcoin, the most important thing is to seek profits. Therefore, the graphics card they use is running and calculating all the time, and its strength is far greater than that of daily game applications. In other words, running such a calculation for one day is equivalent to running a graphics card for one month

in addition, the places where virtual currency is mined are mostly the places where multiple graphics cards gather. Thousands of graphics cards are constantly calculating in a room, and their heat is also quite huge. Miners can not choose the chassis with good heat dissipation conditions like ordinary consumers, so that the heat can be released smoothly. In this way, the graphics cards can still operate for 7 * 24 hours under high temperature conditions, It also deepens its aging degree

the result of doing so is that the graphics cards used for mining are lost prematurely. If you buy these graphics cards, the result will be unstable operation, restart and other things will continue to happen

moreover, at present, manufacturers also have strict requirements on mine cards, such as banning second-hand sales and shortening the shelf life. If users buy these mine card graphics cards, future maintenance will also be a big challenge

2. There's a mistake upstairs. Bitcoin came out in 2009. How could bitcoin mining machine be 7 or 8 years old

now, of course, there are still people mining. There are about 21 million bitcoins in total. At present, there are about 13 million bitcoins in the world, and there are 8 million left. However, now mining is basically large-scale integrated mining machine, and the era of graphics card mining ended at the end of last year, because with more and more bitcoin being g out, the difficulty of mining is increasing automatically, and large-scale mining equipment is manufactured in batches, resulting in that the computing power of graphics card can no longer generate positive benefits
for example, the current mining difficulty is 16818461371, and the computing power of a better graphics card such as ati5970 is 800mhash / s. It takes 2863 years to dig out a bitcoin. The computing power of the large-scale integrated miner can reach 2tash / s, and it will take more than a year to dig out a bitcoin. There are many manufacturers procing this kind of large mining machine all over the world, and the computing power is still improving. Only this kind of equipment has been put into use for more than 100000.

3. As long as it is a regular digital currency, there is an electronic wallet to download

for example, bitcoin, lightcoin, gold card, reborn coin, doggy coin, lightcoin, Ruitai coin, bitstock and other digital currencies can be downloaded from rich packages
but there is no wallet to download MLM or some direct selling coins
for example: Baichuan coin, Morgan coin, treasure coin, etc.

4. If the price of virtual currency is reced, there will be less people to buy graphics cards and fewer people to buy them, which will affect the supply and demand of graphics cards
as long as the supply exceeds the demand, the price will drop

5. The miner that digs bitcoin doesn't use a graphics card. Please understand that there are still two idiots answering the question. First, bitcoin is not closed. Second, there is no direct connection between the two except that bitcoin payment can buy a graphics card. Please have a brief understanding of bitcoin and bitcoin miner before asking. Your question is a typical case of pretending to understand

6. Bitcoin and other currencies will plummet, and the graphics card market will return to normal
the spring of the machine saving party is coming!

7. It's just that all of them are shut down at home, but they are allowed to do so abroad. And now the price of the deposit has gone up a lot. The price drop should not be obvious.

8. Mine disaster, the price is second-hand mine card, new graphics card fluctuation is not so big, in the past because the business speculation, the actual factory price did not change much.

9. Bitcoin is a system that needs the support of many computers. This is how the system is designed. There are only so many coins. As time goes on, less and less coins can be found. Graphics cards are used for mining. In fact, we use a group of numbers to test. If the result is correct, it will be "currency". If the result is incorrect, it will be counted (similar to x-ticket). It's faster to calculate with graphics card than with CPU, so it's better to mine with graphics card
it is people who maintain the platform and want to make money. In fact, bitcoin has no meaning. It is just a string of numbers. It consumes resources and has no value. It is "speculation"—— Someone can buy it.
