You should have been really upfront about this. You can't try to sell something without disclosing something this important. I understand that you ware scammed, but you can't scam other people to get out of your mess, it makes you no better. You were the victim here, but now you are not free of guilt either. Bad decision man.

I will give you a negative trust feedback for this, so others know that they can't buy that wallet from you.
