Could you please elaborate more on how did that guy stole up that amount? Sorry for your loss man since those amounts are quite big and do really suck if you do lose them.Just like been suggested above theres an appropriate board for those accusations which it should really be posted on there on that guy who stole your bitcoins. Theres a certain format on scam accusations just follow it and input valid informations and legit proofs so that person would be tagged and wont able to victimized more people. Sorry for your loss again brother.
