I was impressed by their vision, roadmap and "Black" Paper. I did consider it to be overvalued compared to projects like Zcash and Dash. The recent instamine hack was some bad PR. I initially had my doubts because of the lack of proper funding for a solid dev team (Dash, PIVX, Zcash are all self-funded with a treasury system). The comunity is one of the most hyped and FUD resistant. So I'd be doing some short term buying/selling (as I've done before). But XVG isn't a long term pick for me (at the current state).
