i feel what you say is correct because the price of BTC will keep increasing over time and maybe in the future the value of 1 BTC will be a value of infinity but if you are saying the supply of BTC is infinite then we have to review the value of BTC in the future will be like?.
I think everything what we have at the moment might only vanish in the end or it will keep fourishing until its value becomes very high already. The value of bitcoin will keep in surging because as every year comes, the demand for bitcoin becomes excessive too but i don't think its supply will reach into infinity as everything will have no clear destination in the end. We'll know then when we will reach that point.
