Many coins and tokens are coming out every days and more than 10 are been add daily. How many of this coins and tokens are going to remain in five to ten years to come? I think many of them will become worthless in three years to come as most of them have been abandoned by the developers.
I'm for sure some of them will die or they might get buried in dip. We know already some coins exist today are just scam coins, definitely those coins won't survive as investors won't look for it. Only coins that have firm platform will survive.
