Was listening to BBC radio 4 on the way home from work and they had a story about a guy looking for his hardrive in a landfill site.
He purchased Bitcoins around 3 years ago and then just forgot about them, Three months ago he threw his old computer bits out including the hardrive with his Bitcoin address. He then realised how much Bitcoins had risen from 3 years ago. If he still had that hardrive he would have had 4 million pound worth of Bitcoins. He has been up on the landfill site looking for it and talking to the people who work at the landfill site his hardrive is buried and he has 0 chance of finding it.
Wow I would be so gutted if that ever happened to me
.. never throw away your old computer bits
It was also on the BBC 6 oclock news, poor guy! I would think we'll hear more stories like this as their must have been a lot of people in 2009/10 who bought/mined for the fun for a few months then moved onto something else.
