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 cardfinally, 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
Starting from the essence of bitcoin, the essence of bitcoin is actually a special solution generated by a bunch of complex algorithms. A special solution is one of the infinite (in fact, bitcoin is finite) solutions that can be obtained from the equations. Every particular solution can solve the equation and is unique

the actions in bitcoin can be considered as the use of graphics card to do continuous general computing, and the computational complexity is relatively low and quite repetitive. The stream processor used by graphics card is just suitable for such an algorithm. It's like constantly solving equations. The graphics card is 2000 middle school students, while the CPU is 8 math doctors. Although the mathematical knowledge of the doctor of mathematics is far more than that of the middle school students, the speed of solving medium-sized equations such as virtual currency is certainly not as fast as that of 2000 middle school students
so we used graphics card to mine virtual currency at the beginning. After that, someone developed a specific algorithm to make the stream processor of the graphics card greatly strengthen the virtual currency solution, which is the origin of the mining machine
home computer can't even earn back the cost of digging bitcoin
at present, the home computers all dig up the Leyte coin, because there is no special Leyte coin miner, so it should be able to earn money
hope to adopt.
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.
suggestions for the use of mechanical watch:
1. Watch with manual winding movement should be wound at the same time every day as far as possible, so that the watch can operate with enough energy in the next 24 hours
2. The energy of the watch with automatic winding movement comes from the movement of the wearer's arm, so it is not necessary to manually wind the watch under normal wearing conditions. Only when the wearer's movement is not enough to add enough energy to the spring, the watch can be manually wound up, and the crown rotation is controlled within 20 turns
3. For an automatic winding watch that has not been worn for more than 40 hours, turn the crown for 20 turns to start the drive system of the movement again
4. In order to prevent moisture from seeping into the watch case and keep the watch waterproof, please ensure that the crown is locked at all times
