I don't think every crypto will survive more than 70% will die later on and I think best 20% might still stand the test or time but later on the future who knows. I believe with new and advance technologies other crypto will still be created with time
It's very difficult for all the crypto to survive, we have already so many crypto's out of those only few crypto's have survived and remaining lost their existence because of competency in this crypto world, need to match the expectations or else it would be very difficult to survive in the current scenario.
