I think that 95% of crypto coins and tokens won't survive and the reason is that a crypto coin in order to survive and get value it has to be accepted as a way of payment for purchase goods or services.
Very few coins will manage to do it at the end of the day and of course these coins will get enormous value.
The only thing you have to do is to find out which coins will enter the market of real currencies.
I don't think so, it won't be possible for all the coins in Crypto to survive, there will be so many coins that die, and that can last only a little. it will be good because coins that are scam will die and we can invest more safely.
