Waves has very good fundamentals and I agree that it is heavily undervalued at the moment. I think that their marketing has failed big time when compering with some other projects. It seems that hype is making a big part of market evaluation and Waves just doesn't get any. Furthermore, they don't have a charismatic figure like Vitalik for ETH.
Nevertheless, as I already said I like their fundamentals and will probably invest more in the project. They should be good long term investment but don't count on quick profit.
