My view is very simple.

Most cryptocurrencies are tied to projects on blockchains. They are technological ideas that someone had. Anyone who knows Silicon Valley VCs knows the failure rate is 90%....they look to hit on 1 out of 10.

This is not different. Many of these projects are legit yet will still fail. There are many reasons why projects fail, lack of funding, lack of expertise, no market, too early, etc...

So I agree. Many of the alt-coins that are out there will die as the projects they represent prove themselves to be ill conceived or simply failures.
