A Ka mining area

1. In terms of warranty, n card is generally guaranteed for 3 years, while a card is usually only guaranteed for 1 year
in terms of eth, a card generally needs to brush the BIOS to achieve the highest computing power, and it needs to install a special mining driver
the N card is easy to operate, and the driver can be installed at will. However, the price performance of a card will be higher than that of N card after digging eth
however, in terms of mining life, if eth can't dig in the future, a card may cost a lot. For the time being, a card can only dig Eth and Zec. Zec has proced professional mining machines. In the future, it may not be cost-effective to dig video cards. There are really few currencies that a card can dig. N card is different. Although eth is slightly lower than a card, n card supports many algorithms. There are more than 100 counterfeit coins that can be g. One day, Eth and Zec collapse, and you can continue to live by changing any currency. Aiminer supports both a-card and n-card mining.

2. Dig with n card, you can't even collect the electricity fee... If you want to mine, you'd better use a card honestly

mining machine risk

1. The problem of electricity charge

in order to make the graphics card full load for a long time, the power consumption will be quite high, and the electricity charge will be higher and higher. Many professional mines at home and abroad are operated in areas with extremely low electricity charges, such as hydropower stations, while more users can only mine at home or in ordinary mines, so the electricity charges are not cheap. Even in a certain residential area in Yunnan, there was a case of crazy mining, which led to a large area trip of the residential area, and the transformer was burned

2. Hardware expenditure

mining is actually a competition of performance and equipment. Some mining machines are composed of more such graphics card arrays. With dozens or even hundreds of graphics cards, the cost of hardware and other costs is very high, and there is a considerable expenditure in mining

3, currency security

the withdrawal of bitcoin requires hundreds of keys, and most people will record this long string of numbers on the computer, but the frequent problems such as hard disk damage will make the key permanently lost, which also leads to the loss of bitcoin

4.

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

extended data:

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

5. Not only can a card mine, but a card mine the highest efficiency, n card and CPU can mine, but under the efficiency, you dig out the virtual currency is not enough to pay your electricity, a card's floating-point computing ability is its own strength

6. Not only can a card mine, but a card mine the highest efficiency, n card and CPU can mine, but under the efficiency, you dig out the virtual currency is not enough to pay your electricity, a card's floating-point computing ability is its own strength

7. This is because of the different working principles of a card and N card. N card uses part of the performance to allocate work to stream processor, while a card uses heap stream processor. Although the difference between the two is not big, n card will be faster under some optimizations, but under the full load of mining, the performance of heap stream processor a card will greatly exceed that of N card. So we all use a-card mining.

8. In China, there are stores that accept digital currency payment, but the influence of these stores is generally very small, which can be used as a form of barter. Because at the end of 2013, the central bank and other five ministries and commissions jointly issued the bitcoin risk notice, which clearly defined bitcoin as a special Internet commodity. People can buy and sell bitcoin freely at their own risk, but denied its monetary attribute. At this stage, bitcoin cannot and should not be used for payment
it's also applicable to the younger brother of bitcoin such as Wright coin, Ruitai coin and doggy coin, but there are still stores accepting them offline, but the scope is very small.
