Video game retailer turned meme stock GameStop is considering investing in bitcoin and other cryptocurrencies, according to sources familiar with the matter.

GameStop is exploring investments in alternative asset classes, including crypto and bitcoin in particular, three sources said. Shares of GameStop soared as much as 20% in extended trading following the news.

A computer engineer who lost £620m-worth of Bitcoin wants to buy the tip where he believes it was buried.

James Howells, from Newport, claimed his ex-girlfriend mistakenly chucked out a hard drive containing 8,000 bitcoins in 2013.

He tried to sue the city council to get access to the site on Newport's Docks Way, or get £495m in compensation, but his case was dismissed by a judge.

Newport council said it was making no further comment on the matter.

The authority is planning to close the tip in the 2025-26 financial year.

It has planning permission for a solar farm on the land, expected to power the council's new bin lorries.

Mr Howells said: "The council planning on closing the landfill so soon is quite a surprise, especially since it claimed at the High Court that closing the landfill to allow me to search would have a huge detrimental impact on the people of Newport, whilst at the same time they were planning to close the landfill anyway."
