Bitcoin is based on an increased demand an a deflationary supply, however that eventually leads to a coin that people don´t use to trade or to transact. What do you think that the emission rate of a crypto should be to be used as a coin? Any automatic mechanism to adapt exists?
The market cap is humongous it takes more than a whole country to entirely deflate the supply of Bitcoin. As it grows rapidly due to buyers the price gets higher and the supply slowly decrease its numbers due to its expensiveness. Deflation is part of the cycle.
