Kristoffer Koch invested 150 kroner ($26.60) in 5,000 bitcoins in 2009, after discovering them during the course of writing a thesis on encryption. He promptly forgot about them until widespread media coverage of the anonymous, decentralised, peer-to-peer digital currency in April 2013 jogged his memory. The creator of Bitcoin remains an enigma, known only by the pseudonym Satoshi Nakamoto. Bitcoin's innovation emerged in 2008 when Nakamoto released the whitepaper outlining the cryptocurrency's decentralized, peer-to-peer structure, and use of blockchain technology. In 2009, Nakamoto mined the first Bitcoin block, and on January 12th of the same year, the inaugural Bitcoin transaction took place. Despite numerous investigations and speculations, the true identity crypto com help of Satoshi Nakamoto has not been disclosed.
