A father who lost a £630million Bitcoin fortune when his girlfriend threw his computer out has finally given up his eight-year fight to find it.

Computer expert James Howells, 39, lost 8,000 bitcoins when his former partner threw out a bin bag containing computer parts from their home in 2013.

Since then the cryptocurrency value has sky-rocketed and James has been battling with his local council for the right to search a rubbish dump in Newport, Gwent, for his buried treasure - now worth over £717million.

The father-of-three launched a legal bid for permission to search the council-owned dump but his case was thrown out by a judge earlier this year.

He has even offered to buy the landfill site from Newport City Council after being backed by hedge-fund millionaires wanting a slice of his fortune but his offers were rebuffed.
