Reading that topic, nobody stated that he was an employee of Primedice. I think he just found a loop-hole in the software and exploited it. I think the admins should of checked the server logs prior to sending his winning withdraws but they probably didn't look too deeply into it at the moment. Looking at the way he bet, it did look like legitmate bets and you would just assume he has "really deep pockets" and feels comfortable taking "huge bets".

No idea where the coins went. I don't think he could deposit them into an exchange and cash out. Most likely he either sold them privately or OTC or they are still sitting in some wallet somewhere doing nothing.
