Is it me or does the original post seem a little suspect? Forget the back story as this may or may not have happened, we will never know.
On the face of it, a new member asks advice on how to scam / commit fraud?
Yea, the ~700 BTC sounds weird, is this 700 BTC or 0.700 BTC? Someone with 700 BTC <$4 458 000> can hire a army of hackers with bot farms to attempt this.

Obviously he said he does not have the 700 BTC anymore, but he said it was not a lot, so I am guessing he has a lot more, if 700 BTC is not a lot to him.

Why does he not reply or give details about the scam, if this really happened?
