Bitcoin has max 21 million coins, this low amount gives it that fundamental value.
Can a altcoin with a billion max supply reach $100 each?
Has any alts in history with a billion or billion+ but no more than a trillion coins reach $100 each?
Well, technically speaking it is not about how many there is of a coin, price of it obviously gets affected but it is about how much people are willing to pay for it. So let's assume there is a project with 1 billion max supply, and all of it was mined as well, it could be under 1 cent, it could be over 100 dollars, it all depends on how much people are willing to pay for it.
So far we never had 1+ billion one with 100 dollars because that would mean 100 billion marketcap and only coin that broke over that is bitcoin I think, maybe eth did too I am not sure but I do not think so.
This is why there hasn't been any coin with 100+ billion dollar market cap let alone any other specific requirement aside from bitcoin which has 21 million max supply. This is why I think it would be hard, but technically speaking what makes a coin worth something is not only the supply, there are other things.
