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, not all crypto will survive knowing that not everyone will support each and every crypto existing right now, they will only support those that has the capability to grow and survive more. If we are going to analyze it further more, by just having the fact that crypto is being banned in some country, it already shows that some crypto won't survive anymore due to lack of demand.
