I am quite sure it is my account.
The receiving address is the one that needs identification :/
Does anyone know how to do a OP_return script under the transaction to notify whomever the owner of this wallet address that a mistake was made?
I am unsure how it works.
So this is no longer a scam accusation? Lock the thread. And I'm quite sure that whoever got your 13 BTC is aware of it and throwing good money after bad won't fix it.
