I think if btc mined more the supply will be less.
and the price will be high, so if it's not mine by many people, the difficulty is not high and miners will get many btc
Indeed it is, but on the other hand, if there are fewer miners, don't know if the speed of decoding 1 block will be longer? The idea is that it will cause slow confirmation of 1 hash. Gradually users will find it inconvenient to use and trade with BTC, then gradually will users abandon BTC and choose other crypto?
