Bitcoin investment of $22 yields fortune for Norwegian man
A $22 investment in the virtual currency Bitcoin four years ago has brought a Norwegian man an unexpected windfall of about $850,000.
The staggering appreciation of the Bitcoin meant Kristoffer Koch, 29, was able to buy an upmarket flat in Oslo by selling one fifth of his 5,000 coins.
Mr Koch, 29, told Roger Hearing on the BBC World Service's Business Matters that he had ''more or less forgotten'' about his investment in 2009.
