P2200 mining capacity

1.

mining has been successful, a total of one equipment (CPU mining, 4-core bar), computing power: 12.75 khash / S (generally abbreviated as KH / s)
KH / S is very rare, so is MH / s; Now the more common are GH / s, th / s, pH / s. The conversion rate is about 1p = 1000t = 1000g = 1000m = 1000K

now the basic unit is GH / s, and several hundred g mining machines are very common

[bitcoin mining machine]

bitcoin mining machine is a computer used to earn bitcoin. This kind of computer generally has professional mining chips, and 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

the popular digital currencies in 2013 are bitcoin, Leyte coin, zeta coin, pennies (Internet), invisible gold bar, red coin, pole coin, barbecue coin and prime currency. At present, hundreds of digital currencies are issued all over the world

2.

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

3. From cheap electricity to centralized mining, China's resources and environment provide bitcoin miners with many advantages. In recent years, bitcoin miners have used cheap electricity to expand their business in coal rich regions such as Xinjiang and Inner Mongolia, which are home to the founders of some of the world's leading mining companies

with the rising price of bitcoin, more and more people join the bitcoin mining business. Accordingly, mining consumes more and more energy. Obviously, our government is also aware of this

according to the requirements of the document, regulators require local governments to take measures related to electricity price, land use, tax and environmental protection to guide bitcoin miners to withdraw from the business. According to foreign media reports, regulatory authorities are mainly concerned about the money laundering and financial risks involved in the shutdown policy, but excessive power consumption is also a factor that can not be ignored. In principle, bitcoin mining consumes a lot of power because every time a new bitcoin is proced, it needs to solve the complex mathematical problems through the encryption process performed by a high-performance computer. Mining calculation process is used to verify bitcoin transactions in the blockchain to ensure security, but the disadvantage is that it consumes a lot of energy.

4. The difference between mining by Sifang computing power users and mining by mining machines purchased by indivials is as follows:
①. Early stage investment: Sifang computing power provides, which saves users this link. Indivial: purchase of mining machine, selection of mining machine model, preparation of power facilities, etc
2. Field equipment: provided by Sifang computing power, users can save this link. Indivial: rental site, mining machine support rack, noise elimination equipment, etc
3. Software assembly: provided by Sifang computing power, users do not need to master professional knowledge. Indivial: learn professional software assembly knowledge or hire a special person to operate
4. Maintenance: Sifang computing professional technical team, all-weather supervision and maintenance. Indivial: employ professionals to supervise and maintain all day long< (5) electricity and electricity charges: professional large chain mines and users do not need to pay electricity charges. Indivial: the power facilities in the residential area are unstable, the price is high, and the cost-benefit of mining is unbalanced< (6) risk taking: users obtain BTC net assets. Indivial: the equipment investment in the early stage is huge, which is easy to form heavy asset operation, and the income and investment in the later stage are likely to be unequal.

5. 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.

6. There must be damage. First of all, only a card can be used for mining, and N card is boring for mining.
secondly, the computer needs to be running all the time and can't be turned off for mining, which requires a lot of computer. It is harmful for each part to do a lot of calculation for a long time, and it also requires high power supply for the computer
mining can't be powered off, and it needs to be recalculated after power off. Graphics card long time to do a lot of calculations will lead to greatly shorten the life of the graphics card, so their own home, do not recommend mining, mining is not as expensive as electricity

7. In January 2013, Avalon released the 60g / s miner specification and accepted the booking. In January 2013, Avalon delivered the world's first commercial bitcoin ASIC miner, and the core developer of bitcoin network, Jeff
garzik, was fortunate to be the owner of the first commercial ASIC miner.
the most difficult mining problem was 0, and the computing power was about 2p at the beginning of 2013, and now it has reached 100p

8. Hello

the graphics card can be used for mining

if you have money, you can go to Titan array with high efficiency. If you don't have money, you can use 7990 290x array for more than 1000 yuan

computing power is the ability of bitcoin miner to proce bitcoin and hash collisions per second. The unit conversion relation of calculation force is 1000g = 1t, 1000t = 1p. Now the total calculation force of the whole network is about 2000p. In the world of bitcoin, the total proction in a day is about 1800. Mining can be abstractly understood as the 2000p computing power fighting for 1800 bitcoin proction rights every day. The rise and fall trend of computing power is positively related to the rise and fall of currency price, and negatively related to the rise and fall of mining machinery price.
