Computing power of ordinary desktop mining
You can't dig in a day. It takes 2000 years
the global unified computing difficulty of bitcoin is 2621404453 (expected to change in two days). It takes more than 2000 years for a 2.5GHz CPU to work out a bitcoin
in order to make the graphics card fully loaded for a long time, the power consumption will be quite high, and the electricity bill 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
extended data:
bitcoin network generates new bitcoin through "mining". In essence, the so-called "mining" is to use computers to solve a complex mathematical problem to ensure the consistency of bitcoin network distributed accounting system
bitcoin network will automatically adjust the difficulty of mathematical problems, so that the whole network can get a qualified answer about every 10 minutes. Then bitcoin network will generate a certain amount of bitcoin as block reward to reward the person who gets the answer
when bitcoin was born in 2009, block rewards were 50 bitcoins. Ten minutes after its birth, the first 50 bitcoins were generated, and the total amount of money at this time is 50. Then bitcoin grew at a rate of about 50 every 10 minutes. When the total amount reaches 10.5 million (50% of 21 million), the block reward will be halved to 25
when the total amount reaches 15.75 million (5.25 million new output, i.e. 50% of 1050), the block reward will be further halved to 12.5. The monetary system used to have no more than 10.5 million in four years, after which the total number will be permanently limited to about 21 million
Some new virtual digital coins can be mined by computer, such as eth, Zec, Monroe, XRB, etc
because the whole network computing power required by this kind of token is not high, the probability of hash collision of the computing power of personal computer can find out the answer in a short time, so as to obtain the block reward. However, this kind of token generally has little value, or has no high risk, so it doesn't mean much

mining risk:
1. Electricity charge:
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 mining has a considerable expenditure
in addition to the display card burning machines, some ASIC (application specific integrated circuit) professional mining machines are also put into the battlefield. ASIC is specially designed for hash operation, and the computing power is quite strong. Moreover, because their power consumption is far lower than that of the display card, they are easier to form scale, and the power cost is also lower. It is difficult for single chip display to compete with these mining machines, This kind of machine costs more
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. System risk:
system risk is very common in bitcoin, and the most common one is bifurcation. Bifurcation will lead to a drop in currency price and a sharp drop in mining income
however, many cases show that the forking will benefit the miners, and the forked competitive currency also needs the miners' computing power to complete the minting and trading process. In order to win more miners, the competitive currency will provide more block rewards and handling charges to attract miners. Risk makes miners
mining can be done with an ordinary computer, which is awesome. How much you can dig in a day depends on the computing power of your computer
don't hesitate, just get on the car and dig up
bus line: Line 5 → port line 3, the whole journey is about 5.3km
1. Take line 5 from Bantian, pass 2 stops, then reach Min station
2, walk about 260m, then reach shayuanpu station
3, take port line 3, pass 3 stops, then reach Shaxiao station (also take No.324, no.m282, tourism line 3, no.m262, No.333, No.339, no.334, no.352, no.620)
4 Walk about 340 meters to Sasaki Xiangsong shopping center
Notebook can be used for mining
most virtual currencies use a mechanism called proof of work (POW) to distribute rewards, and the core process is hash operation. So ordinary computers can also mine
ordinary computers can be used to dig bitcoin, because mining itself is just computing. Professional mining machines dig well, dig fast and earn a lot. Ordinary home computers dig slowly and earn less
for example, there are mature professional mining machines for mining bitcoin and lightcoin
extended data
because of adhering to the principle of server construction, the whole mining machine is miniaturized, and the specially designed mining chip is adopted, which is born for the optimization of bitcoin / lightcoin algorithm, with a single computing power of th / s level. However, in order to ensure stable operation, the chip will be covered with aluminum cooling fins, which will be blown through by the front and rear violent fans, but the noise is high, so it is usually placed in a factory
in addition, this kind of professional miner is expensive and uses customized chips. If you don't mine, you can't use it again. In short, you can't do anything except mine
however, if an ordinary computer is a little more professional in mining, it is necessary to select a motherboard specially designed for mining, for example, a motherboard with 10 PCI X1 interfaces, a PCI to USB expansion board and other hardware, and modify the graphics card BIOS at the same time, so as to achieve more powerful computing power and indirectly increase revenue
