Is this an address or an account? The bad guy used a bunch of this to defraud me of the money, but I understand by myself that it has nothing to do with the currency, and at the same time the key exists with this address, and I downloaded the wallet and opened the address and found that it was not Nothing, is this valuable?
Is it machine translation or you translate it manually?
Depending on how much you lost, you might want to consider getting law enforcement involved, but I wouldn't keep my hopes up.
Just don't forget to check the regulation on your country, since Bitcoin is illegal (or legal with some limitation) on some country.
