Cầm vàng còn để vàng rơi

James Howells' life changed when he threw out a hard drive about the size of an iPhone 6.

Howells, from the city of Newport in southern Wales, had two identical (giống nhau) laptop hard drives squirreled away (cất giấu) in a drawer (ngăn kéo) in 2013. One was blank; he says the other contained 8,000 bitcoins — now worth about $181 million, even after the recent crypto crash.

He'd meant to throw out the blank one, but instead the drive containing the cryptocurrency (tiền điện tử) ended up going to the local dump (bãi rác) in a garbage bag.

Nine years later, he's determined to get back his stash, which he mined in 2009.

Howells, 36, is hoping local authorities will let him stage a high-tech treasure hunt for the buried bitcoins. His problem is that he can't get into the dump.

For almost a decade, Newport's city council has denied his requests to dig for his hard drive, saying it would be expensive and environmentally damaging, but Howells is not deterred (nhụt chí, nản chí).

He gave Insider a first look at his new $11 million proposal — backed by venture-capital funding — to search up to 110,000 tons of garbage.
