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.
95% of the coins will not survive? you certainly exaggerate too much. However, I think that about 30% of the coins most likely will not survive, due to the lack of product and uselessness for society. I certainly did not take into account SCAM projects
