Cryptocurrencies have become perhaps the most revolutionary innovation in international finance in a decade. Although the invention of Bitcoin in 2009 by enigmatic Satoshi Nakamoto served as a starting point for this revolution in digital assets, it was the development and spread of crypto trading platforms that actually released the full potential of this new financial system. They serve as the portals through which people, institutions, and even states access the buying, selling, and custody of digital currencies. Without them, there would be no crypto economy today.
