Lesson 1: Cryptocurrencies And Bitcoin
You learned that in centralized monetary systems, such as the U.S. Federal Reserve System, government controls the supply of currency by "printing" units of money, called fiat. Bitcoin on the other hand, is a decentralized cryptocurrency, invented in 2009 by Satoshi Nakamoto. It can be freely transferred between people all over the world, without the control or limitations usually imposed by banks or government authorities. Bitcoin is by far the most popular digital currency and it has tens of thousands of programmers and entrepreneurs around the world developing new services and apps. It is considered safe compared to other digital currencies, has no 3rd parties, is deflationary, and open source.
