And do they have a future in general?
I think regulation can be good...right now just seems like there are so many (potential) scams.
Yes I did. Have bought some on LHCOIN (Lhcrypto). The project is very feasible and promising. It's a introduction of Larson&Holz an international brokerage to the cryptocurrency world. The project is "back up" by a legit company so I'm sure there's no scam here.
