I think that most will die out tokens of all sorts of different projects, altcoins will also disappear, but not as quickly and not in such a large amount as tokens.
Bitcoin together with the altcoins (not all of them) can survive and I don't see that altcoins will not survive, at least from my perspective.
If altcoins will be shut down (which I don't think because there is a lot of potential outside of bitcoin) as most people have benefits from crypto (bitcoin and altcoin together)
