Man seeks to excavate landfill that allegedly has half a billion dollars worth of bitcoin

Newport, a seaside city in Wales, is famous for its docks and industrial heritage — and for allegedly having half a billion dollars worth of Bitcoin buried in its local landfill. 

Former IT worker James Howell mined the cryptocurrency back in 2013, well before its value skyrocketed. In a mix-up, he accidentally threw away the hard drive its access key was stored on. 

"I found a blank 20GB hard drive in my drawer instead of thousands of Bitcoin," Howell told CBS News.
