Yes, i have received unexpected crypto before, which occurred during P2P transaction at binance exchange. I reached terms with the sender of the funds as a recipient, all of sudden the sender cancelled the transaction due to network delay according to him.
But he never knew that the funds went in the other way, and i received alert without the sender's notice. I was wondering where the funds came from, because i did not know that it was from the first dealer. Until he called after his bank sent him debit alert, and he explained everything to me how the transaction was done out of weird luck. It was a total of $200 worth of BTC which he sent to me unexpectedly via fiat currency.
I did not hesitate to send him the funds back because he is correct about the information he given to me. I don't like scamming people i love being straight forward even if the funds are worth million dollars i will still send it back to the owner because it was not meant for me.
Have you experienced such before?
How did you act when you find out that the owner wants the funds back?
