I think that as well as Bitcoin and Litecoin, they both need innovation. Just take a look at other alt coins out there. Ethereum and Bitshares have smartchain technology, Peercoin has PoS, NXT has smartchain, asset exchange, etc. Even still, I think Bitcoin and Litecoin are still alive because of their marketcap and they have more users than the rest of the cryptos. Just my opinion.

Or, just perhaps, the market is trying to tell us that all these other features that these other coins have are all worthless.
Kind of hard to argue against the invisible hand of the marketplace.
