I as well agree many altcoins will die and for a good reason. Many projects are adding blockchain to their existing business but this added currency adds nothing to the project itself.. Blockchain is like this cool thing that they should have. But they do nothing for the whole ecosystem so I'm glad those projects will perish
I hope so too. They are not adding anything valuable to our lives. Mere adding blockchain doesn't make them cool, they are just too much and there are just too many of the same thing without any original purpose or message.
