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.
In order for the coin to survive above all, it is necessary that the project that created this coin be successful and profitable. It is necessary to understand that a coin can be compared with shares, which reflects the success or failure of a company or project.
