This man's lost bitcoin are now worth $75m – and under 200,000 tonnes of garbage

Pity poor James Howells. He has 7,500 bitcoins... but they're lost on a landfill in Newport

What does it feel like to lose $75,000,000 in bitcoin? James Howells tries not to let it get to him. And strictly speaking, he knows where his coins are — they're under 200,000 tonnes of garbage at a landfill in Newport, South Wales.

Back in 2009, Howells set an old laptop to mining bitcoin – back before you needed specialised hardware – eventually totting up 7,500 coins. He later broke up the Dell M1710 into parts to sell on eBay, but kept the hard drive tucked away in a drawer in case bitcoin ever did take off. Four years later, he'd forgotten about his horde, and during a clean out, the hard drive was accidentally binned, presumably landing in Newport landfill. At that time, his bitcoin stash was already worth millions. Thanks to the digital currency's value skyrocketing from between $300 and $1,000 in 2013 to more than $10,000 this week, his pile is now worth $75 million.Why isn't he frantically digging through refuse? For that matter, why aren't you? The council won't allow it – it's dangerous and difficult. "I haven’t actually tried to search for the hard drive yet as I haven’t been given permission to look despite having financial backing in place and engaging the local council a number of times," Howells tells me via email. "Digging up a landfill is not as easy as just digging a hole in the ground." It would require diggers, plenty of specialist help, and, Howells says, be the first such excavation that wasn't related to a criminal investigation in the UK – though such an effort has been done in the US to retrieve dumped ET Atari cartridges.
