No doubt that bitcoin will continue to dominate. But to be honest I see a lot of potential in the altcoins, especially the ones that are built upon Ethereum, which have utility and good strong technological applications. Other than that, I don't see much value, because with all this mainstream media attention this bubble is bound to blow up any time soon.
Some interesting projects to look for are those that solve tech problems: appcoins, omisego, raiden, etc..
