Kristoffer reminded his Bitcoins in 2013 when he saw a newspaper article on the spectacular ongoing progression of Bitcoin.

He sold his 26$ of Bitcoins for...close to 900.000 dollars and purchased a luxurious appartment in Oslo. But it is not the end : less than a year later, he again invested massively in Bitcoins, predicting that it cannot else but continue to grow. His porfolio is now valued 2.3Mn$.
