The journey of crypto exchanges mirrors the evolution of the cryptocurrency industry itself. The first platforms were basic forums and peer-to-peer websites where trades happened informally with little security. Over time, centralized exchanges emerged with professional interfaces, liquidity, and regulatory structures. Today, exchanges have transformed into multi-service platforms offering derivatives, staking, lending, NFTs, and even credit cards. This section highlights the milestones of this journey, from early pioneers like Mt. Gox to modern giants such as Binance and Coinbase, illustrating how innovation and regulation have shaped the landscape.
