Actually, the account was sold, not hacked. I have proof the original user above (based on bitcoin address) is the seller.
The user above didn't provide the private key when requested, and deleted telegram after the deal. Stole 0.08BTC for this account.
Theymos, take this into consideration, if anything scrap this account. Do not give it back to the owner who ripped me off almost $500 for this account.
