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
Bitcoin is actually a virtual currency. When bitcoin first appeared, if you want to get bitcoin, you have to get bitcoin through mining. Therefore, bitcoin mining appeared. But bitcoin mining is more and more difficult, so it is very difficult to get bitcoin now
so now many people use Haru miner digs Ethereum, Monroe and other virtual coins. Most importantly, BTC can be directly equivalent in the end

3. Murderer in the moonlight
this incident was included in the murder network book, which said that the murderer was a sexual sadist, but there seems to be no evidence to prove this. In the first half of 1946, two baby boys and three baby girls were killed in small towns in Arkansas on the night of the full moon. The police have not been able to crack it, but a few days after the last murder, a very suspected man committed suicide on the rail. Why is he very suspected?

6. The murder of a woman in a truck in Brighton
this case is extremely mysterious. It should have been solved, but it is still a mystery today. On June 17, 1934, a truck stopped by Brighton railway station, and the smell came from it. The police found a female corpse in it. She was in her 20s. She was obviously a high-class girl in terms of dress, and she was three months pregnant. Despite all the efforts of the British police, they failed to identify the dead. She was also coated with olive oil to prevent bleeding. It seems that the murderer is a doctor. There is evidence that the truck passed through London Bridge.

As a result, some later called the case "perfect murder"
7. Missing pages case
the case that happened in Los Angeles in January 1947 is very interesting from a psychological point of view. The murder was very cruel. The body was cut into two parts from the waist.

After the crime, the killer mailed the address book of the deceased to the police, who investigated each of them, but made no progress. Finally, when the experts verified the address book, they found that one page was missing, and they couldn't see it from the outside. The police were fooled

One day, Wallace (not the two Wallace players playing basketball, of course) received a mysterious call from the chess club, asking him to visit someone at a certain address. After Wallace left, his wife was brutally killed at home, and the motive of the murder can not be judged. Where Wallace went was a fake address. Wallace himself was tried, but could not be found guilty. The police have no clue about the case and can't find any information related to the murder< On September 12, 1953, Shirley, a 14-year-old girl living in Melbourne, Australia, was invited to her first alt party. The boy who invited her made an appointment with her at Richmond station at 8 p.m., which is not far from rimmerben. But she didn't get there. The next morning, her naked body was found 40 miles from merburn. She was smacked to death with a beer bottle. Although the pieces of her clothes were everywhere, there was no sign of her being raped. The mystery of the case is that. When her mother took her to the station at 7 p.m. until the next morning, what happened. Because she is a quiet and shy girl, she will never follow a stranger away. On the other hand, when she said goodbye to her mother, Zeng Jin said that she was going to Richmond station to meet her boyfriend. And where she died was in the opposite direction. In this regard, the police have been unable to explain
