XmR doesn't rise with bitcoin
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

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
When going abroad for physical examination, the local entry-exit inspection and Quarantine Bureau will handle the "international travel health examination certificate" and "international vaccination certificate", and the health officials will ask you to show them when you go abroad
The process of going abroad for physical examination is as follows:1. On the morning of the physical examination, take your ID card, passport, two two inch photos and expenses
2. Routine projects will be allowed to do, and other projects will be recommended by nurses according to the requirements of the school
3. After physical examination, you will get the international travel health examination certificate, which can be obtained within 4 working days after physical examination
Many countries also need to check the AIDS test certificate and vaccination certificate - yellow book "international vaccination certificate", otherwise they will be refused entry In 1986, the State Council forwarded the "several interim provisions of the State Ecation Commission on studying abroad" which stipulates that the health status of all kinds of students studying abroad must meet the requirements of studying abroad, and they must pass the examination of provincial and municipal hospitals and get the health certificate (valid for one year)2. When going abroad for port inspection, the passport should be handed over to the port inspectors together with the passport; When returning to China for entry, the passport shall be submitted to the port inspectors for inspection together with the passport
It must be difficult to dig bitcoin! But you can dig eth or XmR
if you don't know how to choose the mining software, you can try the Hakkas miner , the pure white can dig the mine, and the Alipay cash, which avoids the trouble of trading on the exchange! p>
because the network wide 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 block rewards. However, this kind of token generally has little value or high risk, so it is not of great significance< br />

mining risk:
1. Electricity charge problem:
if the graphics card "mining" needs to be fully loaded 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
in addition to the display card burning machines, some ASIC (application specific integrated circuit) professional mining machines are also on the battlefield. ASIC is specially designed for hash operation, and the computing power is also quite strong. Moreover, because their power consumption is far lower than that of the display card, they are easier to form scale, and the electricity cost is also lower. It is very difficult 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.
