I am only in three coins at the moment, Dash, Monero and Factom. All were very undervalued a couple of weeks ago but all have had strong increases so they are less undervalued now. I think they are still worth a lot more due to their technology but I don't think they are undervalued much compared to the current market environment. Ark is one I am looking at because it has strong fundamentals and the price I think is a bit low compared to the rest of the crypto space. Price should not be the key thing unless you are a day trader (which I am not).
