Someone is trying to buy BTC from me and pay me with carded WU transfers, will this put me in trouble as a receiver?
Don't trust those people who want to buy bitcoin from you and pay you by using a stolen card because that will put you in trouble and take note that he is paying with a stolen money and that is not bitcoin so there is a chance for you to get traced by the authorities because if the card holder will try to find where his money go then it will be a trouble because they can trace you.
