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.
Not at all. A lot of them are going to die out massively because so many of them do not have the kind of product and the kind of project that is built to withstand the years. There is going to be a massive die out of altcoins at some point because people are not going to want to have their money put into scam projects any more and the coins will die out
