I take this one as the closest answer and the possible scenario that occurs on the missing bitcoins. Im saddened that one of the two possibilities is pointing a finger to someone dear to him that does the back job. I hope it wont happen to me in real or anyone else. Its a betrayal beyond money can compensate.
Temptation of money is as greedy and as unstoppable as the earth circle, it wont end as long as we let our world open. Trust no one is the first rule.
