That's what makes Bitcoin so reliable compared to shitcoin, because you can be sure that the supply of bitcoin remains at 21 million coins, and it will not be more. while in shitcoin, you can see that the supply can be so much, there are even shitcoins that have a supply of up to billions of coins and it can even continue to grow over time. so in this case we can see that bitcoin is the only coin whose scarcity is truly guaranteed by its own protocol, and it will not change at any time, unlike shitcoin whose protocol can be changed according to the wishes of its developers. and that is one of the reasons that makes bitcoin look interesting and unique to many of its adopters.
have you considered that it is possible to make a shitcoin with 15 million units that has burn fees incorporated in their structure, no emissions and if you gather the interest of people you can build a flywheel that would also make the price go up over time indefinitely?
I mean, it's not impossible
