I think it comes down to - or will come down to - what the uses of the alt coin actually is. If it's just an alt that has no special features than a more well established coin has, then no, I think those alts will die a death.

I think alts with utility have some type of future, but the truth is, if that utility can be paid for with Bitcoin (and in most cases it can) then what's the point of the alt in the case of the utility?
