When was the bitcoin mine disaster

1. The concept of bitcoin was first proposed by Nakamoto on November 1, 2008, and was officially born on January 3, 2009. According to the idea of Nakamoto, the open source software is designed and released, and the P2P network on it is constructed. Bitcoin is a virtual encrypted digital currency in the form of P2P. Point to point transmission means a decentralized payment system.

2. First of all, you need to understand the time point of bitcoin mining:
a total of 2100W bitcoins are issued, and each block is generated for 10 minutes, and a block rewards a certain number of bitcoins. In the beginning, 50 bitcoins were awarded for each block of mining. In the future, the reward was halved for every 21000 blocks (about once every four years). Now, 12.5 bitcoins are awarded for each block generated. The generation time of each block is 10 minutes, but with the development of computer technology, now the mining calculation power is increasing, so the generation time of a block must be less than 10 minutes, which requires certain control measures to ensure this time. This measure is the difficulty of mining. If the output time of each block is less than 10 minutes, the difficulty of mining will be increased. If the output time is more than 10 minutes, the difficulty of mining will be reced. The difficulty adjustment time is 2016 blocks, that is, 2 weeks
after every 2016 blocks, all nodes will automatically adjust the mining difficulty according to a certain formula. This formula is obtained by comparing the latest time spent in 2016 blocks in this cycle with the expected time (20160 minutes, i.e. two weeks)
new difficulty = old difficulty * (time spent in the past 2016 blocks / 20160 minutes)

3. The people's Bank of China said that bitcoin could not be used as currency clearing. Some bitcoin websites were stolen and began to avalanche

4. Most businessmen and speculators are always interested in things that can be turned into money immediately. Bitcoin is one of them. The specialization of ASIC chips leads to the market separation between bitcoin mining and other Shanzhai coin mining
when the vast majority of video card mining machines and CPU mining machines are in a mine disaster, bitcoin mining with ASIC mining machines will not be affected. As the first big man in the virtual currency circle, bitcoin has become a deep-rooted belief in the coin circle. The total number of 21 million bitcoins also determines the transaction type and value-added of bitcoin
although bitcoin has begun to be recognized by most people, it has not really replaced the world's currency to fulfill its original intention, but it has become a collection beyond gold. The inflation of money, the rection of the total amount of mining and the increasing difficulty of mining all determine its future market prospects. The value-added has been firmly established, so people will rush to dig for mines, Because the bitcoin is actually worth more than gold

5. According to the information published at present, it is difficult to determine whether the British Tek is a pyramid scheme or not, or there is no authoritative conclusion. If you need to know more, you can call 110 and ask the public security organ for screening or verification
the investigation conclusions of public security organs are the most authoritative.

6. Disease analysis: 22-year-old female, disease description (onset time, main symptoms, etc.): laboratory: (1) high total protein (82.4) (2) albumin Low globulin (1.3) (3) high red blood cells (5.18) (4) percentage of lymphocytes (43.3) (5) low average hemoglobin concentration of red blood cells (320) hyperplasia of mammary glands in fatty liver, Regular review is required.

7. Bitcoin is just a string of code generated by a program developed by two Americans, rather than hard currency like physical gold and silver. You may say that it has value. In fact, its value is only for the insiders who play the game. It has no value for stores, enterprises and even the old man who sells vegetables. Maybe you see a lot of appearances, and many people are eager to invest in it. Do you notice that its price fluctuates very strongly, often dozens to thousands of pieces. If it is really valuable, it will fluctuate so much? You think 2000 yuan washing machine is not easy to sell, will 20 yuan to sell to you? If you can find something similar to it in history, I'm afraid it's the gold coupons issued by the Kuomintang ring the war of liberation. Use a pile of paper for your real gold and silver! Don't believe those sophistry. They say that they are valuable and can be invested like stocks. It's pure money!

8. Before this year's BTC proction rection, bitcoin will cause a mine disaster when it is around $3500. After the proction rection, because the proction is halved, theoretically, the electricity cost will be doubled, so the price of the mine disaster after the proction rection will be higher than this point. Mining is becoming more and more difficult. At present, the quickest way is to go to okex exchange to buy directly. Thank you for accepting my answer

9. Characteristics of fund-raising: 1. Fund raising without the approval of relevant departments in accordance with the law, including the approval of departments without approval authority; The departments that have the authority to examine and approve cross provincial illegal fund-raising exceed their authority to approve fund-raising, that is, the fund raiser does not have the subject qualification of fund-raising. 2. Promise to repay the principal and interest to the investor within a certain period of time. Besides currency, there are also physical and other forms of debt service. 3、 Raise money from people who are not specific to society. Here, the "unspecific target" refers to the public, not the specific minority. 4、 To cover up the essence of illegal fund-raising in legal form. In order to cover up their illegal purposes, criminals often sign contracts with investors (victims), disguise as normal proction and operation activities, and maximize their ultimate purpose of obtaining funds by fraud. If the above four conditions are met at the same time, it constitutes illegal fund-raising.
