Compared with legal tender, Bitcoin has no centralized issuer, but is generated through the calculation of network nodes.

Whenever Bitcoin enters the mainstream media's field of vision, the mainstream media always invites some mainstream economists to analyze Bitcoin. Previously, these analyses always focused on whether Bitcoin was a scam. The current analysis always focuses on whether Bitcoin can become the mainstream currency in the future. The focus of this debate often focuses on the deflationary characteristics of Bitcoin. ?
Many bitcoin players are attracted by the fact that bitcoin cannot be issued at will. Contrary to the attitude of bitcoin players, economists hold a polarized attitude towards the fixed amount of 2 1 10,000 bitcoin.
Keynesian economists believe that the government should actively regulate the total amount of money and use the tightness of monetary policy to refuel or brake the economy at an appropriate time. Therefore, they believe that bitcoin's fixed monetary aggregate sacrifices controllability, and worse, it will inevitably lead to deflation, thus hurting the overall economy.
Economists of the Austrian school hold the opposite view. They think that the less government intervention in the currency, the better. Deflation caused by fixed monetary aggregate is not a major event, even a sign of social progress.
Bitcoin network generates new bitcoins by "mining". The so-called "mining" is essentially to solve a complex mathematical problem with a computer to ensure the consistency of the distributed accounting system of Bitcoin network.

Then the bitcoin network will generate a certain amount of bitcoin as a block reward to reward the person who gets the answer. ?

When the total amount reaches15.75 million (the new output is 5.25 million, that is, 50% of 1050), the number of block prizes will be halved to 12.5. The monetary system once did not exceed 10.5 million for four years, and then the total will be permanently limited to about 2 10/0.5 million.
