In the midst of the global financial meltdown in 2008, a mysterious genius under the pseudonym Satoshi Nakamoto presented the architecture for the perfect currency. Bitcoins cannot be forged, and can be transferred worldwide with the simple click of a button, without incurring transaction costs. Although nobody knows Nakamoto’s true identity, his invention of the first decentralised cryptocurrency has taken the world by storm in just a few years. Initially dismissed as unsafe and of interest only to criminals, Bitcoin has seen its exchange rate going up and up, and banks and governments have started taking notice that it is an invention they cannot ignore. This documentary investigates the history of bitcoin, how it works, and what its future holds.
