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.
Of course not all cryptocurrencies will survive. Now the choice of coins on the market is very large, but only those who can be accepted as a method of payment for the purchase or large firms that can support themselves will survive.
