If they are able to stick to the time frames in the road map, and can implement the parts that do not currently have dates such as Smart contracts etc in the foreseeable future, then Waves will definitely be a coin to watch.

I already like Waves, I just leave my coins out Leasing and every week I get a fairly nice amount of tokens back in return. I just log on every month to see if there is anything I need to sell (Such as Mobile Go tokens which were given out during their ICO etc)

all in all, Waves is a Long term hold for me.
