He made an investment to demonstrate his thesis and became an unexpected millionaire.

Koch, who was studying cryptography and computer security in 2009, was working on a thesis about internet encryption. As part of his research, he decided to explore the then-emerging cryptocurrency market. Thus, with just over 27 dollars, he acquired 5000 bitcoins, an amount that at that time had no significant value.

To make that decision, he read a document written by Satoshi Nakamoto, the name by which the mysterious creator of Bitcoin is known in 2008. After finishing his thesis, he completely forgot about his investment and went on with his life.

It was in 2013 when Bitcoin began to appear in the headlines of the media, and Koch remembered his forgotten financial experiment. The first thing he did was recover the access credentials to his digital wallet.

Once he managed to log in, he discovered that those 5000 bitcoins, for which he had paid 27 dollars, were now worth nearly 886 thousand dollars.

He quickly decided to sell 4000 of his 5000 bitcoins. With the profits, he bought a 78 square meter apartment in the Toyen neighborhood in Oslo, a central area in the Norwegian capital.

Currently, the 4000 bitcoins he sold in 2013 would be equivalent to more than 268 million dollars.

Over the years, he has sold small fractions of his remaining bitcoins, thus earning more multimillion-dollar profits. In a recent transaction, Koch claimed to have earned an additional 10 million dollars and still holds cryptocurrencies estimated to be worth over 70 million dollars.
