Good guy you are. can not just sent it back to the address that sent you coin?
coinbase uses other addresses to send coin instead of just the user's generated addresses
OP never said anything about him/her using coinbase
The title says it all. I was expecting two transactions today, they both happened. About forty five minutes after the last expected transaction I received some coin. I am not sure why, but I think it was a mistake. Is there any way I can return the coin to sender? This particular transaction happened on coinbase. A very surprised e-mail after a night out.
