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.
In any case, not all coins will survive on the modern crypto market. After all, thousands of coins cannot be used for trading and conducting transactions. Therefore, it is necessary to recognize the fact that there will always be high enough competition in the crypto market, some projects will disappear.
