USB professional mining machine

1.

At present, the mining machines in the market are mainly divided into two categories, one is PC based mining machine, the other is professional mining machine based on ASIC chip

the general PC mining machine can be used as a home computer, but the CPU performance is weak and the power consumption is high. Professional mining machine based on ASIC chip can not be used as ordinary computer because it has no graphics card and does not support mainstream desktop operating system

extended data:

mining machine is one of the ways to obtain bitcoin is a kind of network virtual currency proced by open source P2P software. It doesn't rely on a specific currency institution to issue, but is generated by a large number of calculations of a specific algorithm. It uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions economically. The decentralized nature of P2P and the algorithm itself can ensure that the currency value cannot be manipulated by mass proction

any computer can become a mining machine, but the profit will be relatively low, and there may not be one in ten years. Many companies have developed professional mining machines, which are equipped with special mining crystal. They are tens or hundreds of times higher than ordinary computers

mining is actually a competition of performance and equipment. The mining machine composed of many graphics cards, even if it is just a garbage card like hd6770, can surpass the single graphics card of most users in terms of computing power

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 are considerable expenses in mining

in addition to the display card burning machine, some ASIC (application specific integrated circuit) professional mining machines are also put into the battlefield. ASIC is specially designed for hash operation. Although the performance may not be able to kill the display card in seconds, it is already quite strong. Moreover, because their power consumption is far lower than that of the display card, it is easier to form scale and the electricity cost is also lower, It is difficult to compete with these excavators. And this kind of machine will be more expensive

2. It may be this problem, or it may be the setting of the miner. You can ask the next pool operators or mining machine vendors. But you can't get much bitcoin with USB. If it's OK to experience mining, it's basically difficult to get profits from it.

3. 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.

5. Unreliable, easy to have problems

6. Well, gas poisoning is also a headache for doctors. Its resial effect is very annoying and can be repeated. At that time, the treatment was almost complete, but it will be repeated and even aggravated after a period of time. Because CO poisoning can cause delayed encephalopathy and nerve apoptosis
you can see the Department of neurology or the Department of acupuncture and moxibustion

8. Wait a few minutes, there is a: 1, dig to the first piece is good, I dig in the fish pond, out of the piece fast

9. Necessary artifact for mining, inscription R7 260x

10. Bitcoin is not for entertainment, it's a way to make money, similar to investment, which is not well known now
