We have all read stories of coins being sent to wrong addresses (typos or badly copy and pastes)
What would you do if 100 Btc landed into your account? (unfortunately this has not happened to me yet)
I wont sent it back to the sender address immediately. I will do verification process. First, I will send a message to the sender to meet me somewhere or do video chat. Then, I will ask about the BTC that was sent to me and to whom it should be given.
