From my diagnosis, the 0.1 bitcoin actually exists in 13PcbKjLBjVUYcSevYELQDc1pLDm6Bb9Di[/b]. I'm sorry for your loss. However, I am not sorry. When copying and pasting a wallet address, you're meant to look closely at what you're doing. When I copy a wallet address (for my little $20 transaction), one of my modes to check if it's OK is checking the first and the last characters of they correspond to that of the source. It could have been better if just a character was tempered with but here, you copied a whole different wallet address and send a whooping 0.1bitcoin without caring if it's destination was right.
