Wow is this really a thread about trade that i don't even know about?
You're basically admitting that the guy got scammed (but not by you).
The sequence of events says you're a scammer. After a hacker scams someone and his cover is blown, he wouldn't try to defend the account. He'll just ditch it. After
xavio4980 posted the wallet address, you were cornered so played the "
wasn't me" excuse. So you coincidentally recovered and changed your PW in a day, after it all happened?
Don't try to dig yourself a bigger hole. Just return his btc, or ditch the account.
