yes crypto currency will survive bcz in feature crypto is creating a very good demand in those days.
Be ready to witness the death of many shitcoins in the nearest 2-3 years. The number of the tokens will be cut sufficiently. meanwhile, the best altcoins and Bitcoin will certainly survive. I am sure of it.
Yes, we'll probably see a lot of coins / tokens die if the bear market continues for much longer. If you compare the CMC snapshots from a few years ago with the one from today, we already see how different they look. A lot of coins disappeared from the top 100. The question is which projects will have a future? I am sure BTC will still be around, ETH aswell.
