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 everybody will survive, because a lot of coins/tokens bring no real value to crypto development space. Also a lot of crypto project have very interesting ideas in mind but they dont develop them, and main reason behind that is not the absence of money but the laziness of the development team, that already made money on the ICO and are not willing to deliver the promised project.
