Four years ago, the girlfriend of an Oslo boy named Christopher Koch scoffed at his Bitcoin . But she likely changed her mind last April, when Koch checked his investment and found it was worth $886,000. That's about a million.
In 2009, Koch was working on a project about cryptography, which led him to the relatively unknown world of Bitcoin. So, he decided to pay $27 for 5,000 Bitcoins because the cryptography process fascinated him. Koch then forgot about the market—until Bitcoin started making headlines four years later, that is…
When Koch remembered his investment, he searched his wallet for the password and was delighted to find it was still there. Using just a fifth of his total investment, he bought an apartment in Toyen, one of the wealthiest areas in Oslo.
