Is bitcoin the blueprint for a bankless currency, or the biggest pyramid scheme ever? When the financial world collapsed in 2008, a mysterious genius under the pseudonym Satoshi Nakamoto presented the architecture for the perfect, bankless currency. Bitcoins can’t be forged, and can be transferred worldwide with one click of a button, without transaction costs. Up till today, nobody knows who Nakamoto is, but his invention of the first decentralized cryptocurrency became world-famous within a couple of years. Bitcoin was initially dismissed as unsafe and only interesting to criminals. But in fits and starts, the exchange rate kept going up, and more and more banks and governments are realizing that bitcoin is an invention they can’t ignore.
