They clearly have to evolve a lot, I mean ether is still not capable of running good dapps in it's platform, and bitcoin still cant scale. But the truth is that, both of these coins have some updates coming, and their devs are good, so their products have a future. I think this has collapsed in the short term, because a lot of money is flowing out of the encrypted money market.
So I think the next bull market will require the death of most altcoin.
