Yes, that guy has been red flagged here multiple times already. Good for you that you made a research before sending your hard earn bitcoins. There are a lot of members here that was already scammed by that guy. I think he has been reported to South Korean authorities already, but I don't know what happened. But it looks like he is continuing with his acts. I just hope that a lot of newbies will not fall for this guy. He had made tons of money, authorities should really track him and send him to jail. Just beware guys especially for newbies out there.
