Raiblocks have gone down a lot. It's cheap now compared to ATH. It's a good project imo, with a good dev team. Zero fees and instant transactions is always nice 
Those features are of course nice, but a lot of new alts are offering those two things nowadays. Are there any other features that RailBlocks has, or is it just another generic coin? I see people on the internet are very optimistic about it, but I haven't read anything so far which made me think this coin is special.
