Every new innovation needs time to be mature. There have both possibilities of dying and surviving. You know that when bitcoin came in the market, many people didn't believe that it will be alive. But then bitcoin made them fool.

Anyway, we should be realistic. I strongly believe that the good Altcoins won't be destroyed. Yet, I also believe that all bad coins will surely have died. Unfortunately, those who say that the Altcoins has no future have not understood the nature of this technology.
