Bitcoin network generates a new block every ten minutes. Every time a miner completes a block, he can get a certain amount of bitcoin as a block reward, and the reward will be halved for every 210000 blocks mined. Because the time for mining each block is limited to 10 minutes, at this rate, the period for the reward to be halved is four years, that is to say, the reward for bitcoin blocks is halved every four years
when the bitcoin block reward was halved for the first time, its price rose 25 times from 300 yuan to 7995 yuan; In the second half, the price rose 28 times from 5011 yuan to 140000 yuan. So many people predict that the third halving of bitcoin in May 2020 will lead to a sharp rise in the price of bitcoin, at least 10 times. However, these figures are not so clear. After halving in 2012, bitcoin prices rose for two months, and in 2016, there was almost no immediate response to deflation for a month. This may also be the result of the strategy of "buying rumors and selling news" implemented by some speculators
extended data:
after bitcoin halved, the supply slowed down, and keeping deflation through algorithm has always been a part of bitcoin protocol design. It was set up to ensure the value of bitcoin. By recing block incentives and setting the maximum possible supply of bitcoin at 21 million bitcoins, bitcoin has an anti inflation feature, which runs counter to the tendency of central banks to print money at will. At present, there are about 17.5 million bitcoins in circulation, and less than 3.5 million bitcoins are available for mining. When the next block award halves, bitcoin's annual inflation rate will drop from the current 3.8% to about 1.8%
maintaining deflation through algorithms has always been a part of the design of bitcoin protocol. It was created to guarantee the value of bitcoin. By recing block incentives and keeping the total amount of bitcoin at 21 million bitcoins, bitcoin is endowed with an anti inflation nature, which is different from the tendency of central banks to print money at will. At present, there are about 17.5 million bitcoins in circulation and less than 3.5 million available for mining. The next block award cut in half could rece bitcoin's annual inflation rate from the current 3.8% to about 1.8%. This will be the first time in bitcoin's history that it has fallen below the historical average of about 2% - 3% growth in gold supply
Recently, the price of bitcoin continued to rise, reaching a maximum of US $41000. According to Mr. Liu, the manager of the mine, recently some customers have asked for additional orders, but the output of the mining machinery manufacturers is insufficient and they can't get a large number of mining machinery. Now they have to wait five months or more. Most of his customers have increased their positions in the middle of this year. At present, the prices of mainstream mining machines vary from 30000 to 60000, Mining takes about 12 months to recover the cost
therefore, if people really have mining ideas, they should not be dazzled by the impulse of the moment, and they should try to do it slowly. Today, the price of bitcoin continues to rise, largely because many mainstream investment institutions or investors begin to be interested in digital assets and begin to hoard bitcoin
bitcoin investment has great risks, the phenomenon of sharp rise and fall is not uncommon, and there are not a few people who have lost all their money. Therefore, it is not advisable to follow blindly and keep calm in investment

bitcoin plummeted by more than 10%:
earlier on January 11, bitcoin once fell to $37000 / piece, the lowest to $35141, and the biggest drop in the day was more than 10%. According to the data of bitcoin home.com, the amount of burst positions in the past 24 hours reached US $1.165 billion (about RMB 7.530 billion), and a total of 115138 people burst positions within 24 hours
for the sudden drop, some netizens said: "what should come will come.". Cautious investors said that such a high position, I first clearance, short about

it is estimated that 21 million pieces will be excavated in 2140

according to the relevant literature of bitcoin, in 2140, 2100 bitcoins will be proced and will not grow any more. According to the principle of bitcoin, after 33 halving periods, the mining output of each block will reach 0.58 Cong, less than the minimum unit of one Cong. The interval of each half rection is 210000 blocks, and the total proction time (2140 years) given in the above literature is calculated from the proction time of each block of 10 minutes 210000 * 10 / 60 / 24 / 365 = 3.9954 * 33 = 132 years. Since 2008, 132 years later, it is 2140 years)
however, the "proction time of each block is 10 minutes" used in the above calculation method is an ideal state, which is only true when the computing power and difficulty of the whole network do not change. Looking at the bitcoin blockchain, it is not difficult to find that bitcoin's whole network computing power has been growing for a long time, and the difficulty of mining has also increased. Therefore, it is not difficult to find out that the above calculation is not tenable and there is a huge error
the shortcomings of the above methods are that they can not accurately predict the change of bitcoin network computing power and the mining speed of bitcoin. The 11.3-day data used in the above calculation method is only the average value from May 2013 to April 5, 2014, and the representativeness is questionable. We can integrate the results of big data analysis and mining machine proction to establish a more accurate mathematical model
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)
