Do you think that the need to increase BTC's max supply will arise in the future? Or will Bitcoin be able to "live" just fine with a max supply of 21 million coins? Your input will be greatly appreciated.

yes maybe if the supply of bitcoin will be increased in the future because there are more bitcoin users. Besides that, the price of bitcoin will continue to rise as users and buyers in the crypto market continue to increase. if the supply of bitcoin is still as much as 21 million coins in the future, but bitcoin is still alive at a price that is much higher than the price of bitcoin today.
