Hextracoin? Didn't I read some drama about it? Why would you refer to a coin that seems to have a lot of trouble?
I bought their coin from the ICO time, their plan was added to nova exchange in this month but nova is going to close. so they must build their own exchange platform, At the beginning, there was a lot of trouble but they fixed and keep their promise, My balance is x15 now. Ucoin may be good, but will not excellent like Hextracoin
Erm Ucoin Cash look good in their website and also better platform too and i quite like it. However nowsday too many many lending platforms come with new ICO coins after success of Bitconnect.
