Mistakes! How interesting? CNBC (Consumer News and Business Channel) once published the story of James Howells. Howells had mistakenly discarded a hard disk with a large sum of bitcoins in it. It was too late when he realized what happened. The hard disk ended up in a garbage dump getting buried underneath tons of waste. Retrieval was not only impossible but illegal. That mistake cost Howell a whopping 127 million dollars in bitcoins! He never saw the hard drive or his precious bitcoins again.
