1. You can refer to the following, according to some commonly used graphics cards in the Internet bar market, sort out the price and calculation power of a related graphics card, as well as the expected return to the current period, It can be used as a reference:

Video card (graphics card) full name display interface card, also known as display adapter, is the most basic configuration of computer, one of the most important accessories. As an important part of the computer host, the graphics card is the equipment of digital to analog signal conversion, and it undertakes the task of output display graphics
the graphics card is connected to the main board of the computer, which converts the digital signal of the computer into an analog signal for the display. At the same time, the graphics card still has the ability of image processing, which can help the CPU work and improve the overall running speed. For those engaged in professional graphic design, graphics card is very important. Civil and military graphics chip suppliers mainly include amd (ultra micro semiconctor) and NVIDIA (NVIDIA). Today's TOP500 computer, including graphics card computing core. In scientific computing, graphics card is called display accelerator
2. The revenue from the purchasing power contract varies from two to three years. You need to book and purchase the
mining machinery in advance, search for electricity or look for the mine trusteeship, which has a lot of deployment costs and electricity costs. It also needs manual maintenance. The mining machinery has a service life. In addition, the mining machinery market is updated rapidly, so the cost of such calculation is very high, and it is also very troublesome.
3. Ethereal currency and Leyte currency are relatively reliable counterfeit currencies, and their market value and influence are second only to
bitcoin. In addition, there are Ruibo coin, Ruitai coin, vitality coin, dog coin and other excellent counterfeit coins.
4. Depending on personal preferences and advantages, those who are willing to take this as their lifelong career can get a mining plant, parcel a piece of land, and hire a few more people to watch the mining machine for you. If ordinary people enter, I suggest that they choose the platform to dig. They are too tired to dig, and the people who come here
5. Bitcoin mining is to use the computing power of your mining equipment to calculate mathematical problems and confirm transactions. The system will give unequal bitcoin rewards according to the amount of computing power you contribute to the whole network. Bitcoin mining has gone through three stages. In the first stage, we use CPU to mine, because there are few people mining; The second stage, we use the graphics card mining, popular point is burning graphics card mining, players began to wake up; In the third stage, professional ASIC mining machines are used for mining. Starting from Avalon's mining machines and the introction of cat roasting mining machines into the market, the computing power in this stage is surging, and the mining difficulty is increasing. In the following period, new mining machine manufacturers continue to join the mining machine instry. However, with the increase of computing power and the progress of technology, Some mining machinery manufacturers began to go bankrupt or fade out of the market. Avalon has always been active in people's field of vision and constantly launched new chips. At present, Avalon has launched three generations of mining machinery chips, and the fourth generation will soon be launched.
6. According to the results of bitcoin mining income calculator on bitfan website:
income: 0.0009 BTC RMB & # 165; 3.09 US $0.50 (at present, the price of bitcoin is about 3600 US dollars, about 580 US dollars, and the mining difficulty is 18736441558)
the mining speed changes at any time according to the mining difficulty
this kind of Power Miner is only for those miners who want to experience mining. In addition to electricity and other costs, there is basically no profit. If you want to get more profit from mining, you have to buy more power miner
for example, the mainstream miner Avalon 290g single-mode miner in the market, you can choose to buy the T-class package.
7. A: first, block height does not refer to the capacity of the blockchain
Second, the connotation of block height
block height is the number of blocks linked to the main chain, that is, the number of blocks connected to the blockchain
Block height is the indicator of block
2. The block has two identifiers, one is the hash value of the block head, the other is the block height
3. The hash value of the block head is the number obtained by the second hash calculation of the block head by sha256 algorithm
The
block hash value can uniquely and explicitly identify a block, and any node can independently obtain the block hash value by simply hashing the block head
4. Block height refers to the position of the block in the blockchain
The
block height is not a unique identifier
8. I can only tell you that it's not caused by mining. In fact, the computing power of 480 and 580 is very weak. The double precision of a card is reced every year. Every time GCN architecture is updated, the double precision will be reced by twice. For example, the double precision of 7970 / 280x of the first generation GCN is 1000, and the single double ratio is 4:1. By 290 and 290x, it becomes 8:1, fury x is 16:1, and there is 500 left, When it comes to Polaris (480 / 580), it's 16:1, and the double precision is only about 360
at present, mining machines are used in mining. If the mining capacity of 280x is 1, the mining capacity of mainstream mining machines is several thousand times that of 280x, let alone 480 and 580.
9. The driver is not installed properly. Another 580 is asus's best
10. First of all, which brand is 580? Second, the difference between N card and a card is also different. N card supports OpenCL mode, and CUDA mode mining tool is available. In CUDA mode, the performance of gtx580 is 30% higher than that of OpenCL mode. In CUDA mode, not only the performance is improved, but also the power consumption ring mining is reced, from 366 watts to 329 watts. This shows that the algorithm efficiency of CUDA mining is better than that of OpenCL mining, but e to the limitation of its own computing power, it is not as good as a card with massive stream processor. How much can we dig is to be tested
