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 have told it many times yet. Of course not every coin will survive. I can tell you even more about it. In my mind at the end only coins which are at the top-100 will stay on the cryptomarket.
