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 all coins are made to be used as payment tokens/coins so you can't really classify your statement in this way. Any cryptocurrency will be there as long there are 2 existing nodes, question is if devs will continue development and question regarding the price. I don't think that 95 will get burned, I do believe that as ears pass by we will see many new ones out there.
Yes I believe it that way that many cryptocurrencies will not survive, That is true in a sense that many other altcoins is created and growing while others didn't survive. Altcoin needed support. If it is still used, it will not vanish. But if we still support it through trading systems, it will remain alive.
I'm sure for each coin is capable to maintain the situation into a safe position and support for the progress of the market Cryptocurrency. so with all the coins that are present on the Cryptocurrency able to survive and continue to enhance his progress.
