James Howells, an IT engineer from Newport, Wales, has lost his legal battle to recover a Bitcoin hard drive worth more than $770 million, Cointelegraph reported.

The hard drive was mistakenly dumped in landfill following mining in 2009, with Newport City Council refusing access due to environmental permissions.

Welsh Circuit Commercial Judge Keyser dismissed Howells' legal case, saying it had "no realistic prospect of success" at a full trial.

Since 2013, Howells has repeatedly requested access to the site, promising to share some of the Bitcoin if the hard drive is found.
