I mean if the miners agree with the proposal and increase the supply limit to a higher number, technically it will still be bitcoin because the miners have the power to change the network rules.
But how many people will accept it?
let's say a supply increase does happen, and most miners are on board with it, they will be shooting themselves in the foot. just imagine the price crash that would follow, which in turn, will lower their earnings a lot.
i mean, why would anyone continue holding/investing in an asset whose supply keeps increasing?
and how much are they going to increase it by? because if they don't make the supply unlimited, they will have to increase it again, and again, and again... it will become a joke.
no one with a brain would accept this nonsense. the shitcoin they will create will be dead on arival.
