It’s not illegal for a open source project to have dark markets using it , if that was so then Monero and Bitcoin and Eth would be illegal u fucking retard , furthermore it’s currently not on any dark market so point is moot. If u didn’t have ur head up ur ass ud realise The dark markets were busted last year atleast the top ones . Anyway not sure what u mean by buying and selling and buying “ stuff” Currently u can sell adk to btc ... genius . And one more thing . The banking license and everything is in a legal manner and done right with central banking green light , it really is sad u are woefully uninformed . What should be illegal is ur level of stupidity .
