Crypto will not end, that's for sure. Bitcoin is part of the crypto and has been declared dead many times but still here and making progress.
People will make this stay and develop as crypto is a good model of a transparent network since it promoted the decentralized system which is the blockchain.
crypto who will die are those who no longer have trading activities on the market, even those who have not been registered and are still in a long-term plan. many projects that after being registered as registrants then they leave the project without any activity in the group. they will disappear because there is no communication with communism.
like the DSLD token from the DEALCOIN project, there was no development after a long wait to be traded and it turned out that the developer put it on a bad exchange. it shows the seriousness of the developer in running their project.
