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.
This is a great logic, but there is one problem. It is not so easy to understand which projects will live. Of course, this year has opened our eyes to many things, but we must not forget that the market is very much subject to manipulation..
