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.
You exaggerate. The percentage of coins that can take root in real life is actually much easier. It seems to me that you shouldn't think so far now, it is necessary to live today. I will try to do my best to earn enough money now, not after some time
