According to Coinpost, economist Peter C. Earl said that the inflation rate after Bitcoin's half-life would be half of its current level, falling to about 1.8% per year. Theoretically, the ratio is below the 2% annual inflation target set by the Federal Reserve. Bitcoin's limited supply has been attractive to investors and traders familiar with the impact of inflation on purchasing power. Bitcoin is very close to monetary policy, that is, quantitative tightening, which is defined as supply, and its occurrence follows a predictable and transparent agreement. Earle pointed out that Bitcoin's inflation rate is lower than the nominal inflation rate and the actual inflation rate (considering the inflation rate of price fluctuations), and it is likely to make it less speculative. This mechanism may make Bitcoin more attractive, emphasizing certain aspects of its value as a means of preserving value, and causing Bitcoin prices to rise.
