Might know a thing or two about landfills.

The bizarre saga started in 2013 when Mr Howells, put the hardware from an old laptop that contained 8,000 bitcoins, the world’s leading cryptocurrency, in a black bag in his hallway.

"I was doing a clear-out in my office and put a lot of items into a bag which I then placed at the front door of my house," he said. "I woke up the next morning and my ex-partner had already taken the bags to the landfill site; she thought she was doing me a favour, it wasn’t her fault."
