IT consultant James Howells used his laptop to mine Bitcoins in 2009. He managed to accumulate a total of 7,500 Bitcoins, worth around 4.6m. The drive contains the cryptographic private key that is required in order to access and spend the virtual currency. Howells went to a local landfill site in Newport, Wales, to search for the drive but was told a police search of the area would involve mechanical diggers and a team of 15 people with protective clothing. He is now asking for donations towards the cost of recovering the hard drive.”]
