Why does the mine card say it's mine digger
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
In short, mining is the use of chips for a random number related calculation, get the answer in exchange for a virtual currency. 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
In his paper, Nakamoto stated:"in the absence of central authority, it not only encourages miners to support bitcoin network, but also enables bitcoin's currency circulation system to have the initial source of money injection."
Nakamoto compares the generation of bitcoin by consuming CPU power and time to the consumption of resources by gold mines to inject gold into the economy. Bitcoin mining and node software mainly initiates zero knowledge proof and verification transactions through peer-to-peer network, digital signature and interactive proof system
each network node concts broadcast transactions to the network. After these broadcast transactions are verified by miners (computers on the network), miners can use their own work proof results to express their confirmation. The confirmed transactions will be packaged into data blocks, and the data blocks will form a continuous data block chain
Nakamoto himself designed the first version of bitcoin mining program, which was later developed into the first generation of widely used mining software bitcoin, which was popular from 2009 to mid-2010
each bitcoin node will collect all the unconfirmed transactions and gather them into a data block. The miner node will add a random adjustment number and calculate the SHA-256 hash value of the previous data block. The mining node tries again and again until it finds the random adjustment number so that the hash value is lower than a specific target
extended data
at the earliest, bitcoin miners were mining through Intel or AMD CPU procts. But because mining is a computing intensive application, and with the continuous improvement of mining number and equipment performance, the difficulty graally increases, now using CPU mining has no profit or even loss
as of 2012, since the first quarter of 2013, miners graally began to use GPU or FPGA and other mining equipment [5]. At the same time, a large number of ASIC devices were launched in mid 2013
since July 2013, the computing power of the whole network has shown a straight-line rise e to the large number of ASIC equipment put into operation. Based on the average computing power in July 2013, all CPU mining equipment has been unable to generate positive revenue, and FPGA equipment is close to no revenue
according to the estimation of average computing power in September 2013, the existing small ASIC mining equipment developed for indivials will also be close to no positive revenue in the next 1-2 months. A large amount of computing power is monopolized by cluster ASIC mining equipment with 5 th ash / s or more. Because of no profit, indivial mining is almost squeezed out of mining groups. Some bitcoin miners have raised funds to build machine rooms and install a large number of mining equipment in places where low-cost electricity can be obtained
in order to save the cost of mining, some bitcoin miners make mining programs into malicious programs to infect other people's computers on the network to mine for themselves
Mine card refers to the graphics card used by bitcoin mining machine, mostly amd graphics card
mine disaster refers to the decline in the price of bitcoin and the sale of second-hand mine cards
bitcoin mining machine graphics card long-term high load operation, graphics card service life will be reced accordingly, so the price will be cheaper

bitcoin mining machine is a computer used to earn bitcoin. This kind of computer generally has professional mining chips, and mostly works in the way of burning graphics card, which consumes a lot of power. It is one of the ways to get bitcoin that users download software from personal computer and then run specific algorithm to get corresponding bitcoin after communicating with remote server
bitcoin mining started with low-cost hardware such as CPU or GPU, but with the popularity of bitcoin, the mining process has changed greatly. Nowadays, the mining activities are transferred to the field programmable gate array, and the hash speed can be achieved through optimization. The mining efficiency of this mode is very high
a mine card is a graphics card used for mining, that is, a virtual currency used for mining bitcoin or other computing proction. Because of the heavy workload and long working time, the hardware life is often shorter than that of a normal graphics card. Before 2014, only a card can be used for mining, but now n card can also be used for mining. So n card without mine card is not applicable.

Mining card is a graphics card that is specially used for general calculation to earn network currency "bitcoin". Bitcoin can be proced with specific programs, and then sold to people in need to be able to exchange real money, or mining for short
because this program needs a lot of repeated calculations, it is more efficient to use a card with more sp. Because of the full load operation all year round, there are many uncertain factors in the mining card
extended data:
mining is actually a competition of performance and equipment. The mining machine composed of many graphics cards, even if it is only hd6770, the computing power after "group" can surpass the single graphics card of most users
and this is not the most terrible. Some mining machines are made up of more such graphics card arrays. When dozens or even hundreds of graphics cards come together, the graphics card itself costs money. Considering the hardware price and other costs, there is a considerable expenditure in mining
in fact, there are many kinds of mining devices. Guiminer, which is small and easy to use, is recommended. It can support CPU, oepncl, CUDA and other computing modes
in this way, devices including CPU and graphics card can achieve the maximum performance, and then acquire bitcoin more quickly

difference between mine card and ordinary graphics card:
1. The most essential difference between special mine card and ordinary graphics card is whether there is a display interface, and some of them have no or only one interface. Other mainstream HDMI, DVI and DP HD interfaces have been castrated, so they can only be used for mining, It's not suitable for playing games
2. The special mine card is only equipped with PCI-E 1.1 because it only aims at the general calculation application of mining with low bus bandwidth requirements × 16 interface, and the ordinary game graphics card is equipped with a higher specification of the mainstream pci-e2.0 / 3.0 specification
3. Some parts of the new card will be light yellow, but the color of the protective paint at that time, while the core yellow of the mine card is yellow and burnt yellow caused by long-time and high-frequency use of heat and oxidation
