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.
Survive those coins, which will really be in demand, so the developers of new projects need to try hard to make this market really necessary product.And lately I meet,all the ideas are repeated,that they themselves stoked at the bottom!!
Ofcourse Not all coins will survive because not all coins are good, and i think less than half of all the coins today will survive and the rest will die. Ofcourse the one who have many investors have the chance to survive
