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.
Actually, there is a big chance that not all cryptocurrencies will survive and I think the cryptocurrencies are the token who have solid structure and have support of many people. We all know that cryptocurrencies will survive if we keep support and investing on it.
