Can you elaborate on extinct though, you could probably meant no more bitcoins to mine which the answer would be yes, bitcoin could go extinct in a way where miners don't have any bitcoins to mine or you could be talking about bitcoin burning but that's impossible because bitcoin has value and there's not a lot of people that are invested into bitcoin that's willing to part with their bitcoin just for the bitcoin to be burned, although it does help with the pumping in price because there's less and less bitcoin in circulation, you can't really make everyone burn their bitcoin. Another definition of bitcoin extinction that I can think of is probably from the fact that it's life is tied to how long is the survival of the humans in this planet, if we are gone then there's no one that will ever utilize bitcoin because with no one maintaining the power, everything that relies on it including bitcoin will eventually fade out so yes, there's a chance that bitcoin can go extinct but don't worry too much about it because humanity is so obsessed with survival so I don't think that we'll ever see ourselves going extinct, maybe it's not even in our lifetime.
