Yes, if the payment is fraudulent and the bank requests the payment back or the person sending convinces their bank that their account was hacked to try gain free Bitcoin.
My advice is to sell with cash deposit, people put actual cash in your account so it's safe.
But how do I know that the person made a cash deposit or just transferred the money?
I was thinking about using paypal for small trades. Even is small trades I don't want to lose my bitcoins and get chargedback. Anyone who got has experience with being charged back after bitcoin sale please tell me what the buyer would complain about to get the cashback? It cant be that hard to prove that you send the bitcoins to him, right? Anyway I just want to be ready and know what I am facing just in case someone does open a dispute.
PayPal don't support BTC transactions, and it's so easy to dispute you will mostly lose every time.
Also it will show up as DEP or something on your bank statement.
Banks won't care about a Blockchain.info transaction showing you sent the Bitcoin.
