whenever bitcoin comes into the view of mainstream media, mainstream media always ask some mainstream economists to analyze bitcoin. Earlier, these analyses always focused on whether bitcoin was a scam. Now the analysis is always focused on whether bitcoin can become the mainstream currency in the future. The focus of the debate is often on the deflationary nature of bitcoin
many bitcoin players are attracted by the fact that bitcoin can not be issued at will. The attitude of bitcoin players is quite the opposite, and the attitude of economists is polarized compared with the fixed amount of 21 million bitcoin
the price of bitcoin is always floating, so the price of bitcoin for RMB is always changing. From the beginning, a few years ago, when bitcoin was converted into RMB, it was only one to several, and finally it graally developed to one to more than ten, and then to one to dozens. At this time, it has been very shocking, and many people think it is a very strange phenomenon, As a virtual currency, although many people don't know what its main function is, most people think it's a bit similar to stocks, so they made a series of investments in bitcoin. Until January 2020, the value of bitcoin has grown crazily, rising to nearly 1:47000 this growth rate has exceeded most excellent stocks. Many people are shocked and often want to understand why this phenomenon occurs. In fact, my analysis is mainly caused by the following reasons:
3 Of course, one of the main reasons why the price of bitcoin has risen so fast is also related to the psychology of chasing up and killing down. For example, when many stocks have been rising, more people will buy them, but when they are falling, many people withdraw because of fear. So far, bitcoin's rise is still very large, Therefore, some people think it has investment value, so they have been buying it
The total number of bitcoins is 21 million
in 2009, when bitcoin was born, block reward was 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

purchase method:
users can buy bitcoin, at the same time, they can also use the computer to "mine" bitcoin according to the algorithm. When users "mine" bitcoin, they need to use the computer to search for 64 bit numbers, and then compete with other gold miners by repeatedly solving puzzles to provide the required numbers for the bitcoin network. If the user's computer successfully creates a set of numbers, then they will get 25 bitcoins
e to the decentralized programming adopted by the bitcoin system, only 25 bitcoins can be obtained every 10 minutes, and by 2140, the maximum number of bitcoins in circulation will reach 21 million.
