More than 10 years have passed since the first cryptocurrency Bitcoin appeared in 2009. During this time, several thousand new cryptocurrencies and tokens have appeared, and with them the need to exchange cryptocurrencies and tokens among themselves and also between owners. The first widely known crypto exchange took place in May 2010 via correspondence on Bitcointalk.org forum, as a result of which 10.000 BTC were exchanged for 2 pizzas and now the whole crypto community celebrates this day on May 22 as Bitcoin Pizza Day. This method of exchange, although it still exists, but it is extremely uncomfortable and carries a lot of risks for both participants. On the need to conduct exchange operations with cryptocurrencies with minimal risk there appeared intermediaries in the form of trusted users on forums and exchange websites, which also did not solve many problems and first of all the exchange speed. The next step is the emergence of centralized crypto exchanges. The first such exchange was Mt.Gox, which, like many others, ceased to exist with the loss of cryptocurrency stored in its accounts. Over the past 5 years, crypto exchanges have evolved from niche sites to large international companies (Binance, FTX, Bybit) whose trust among users is already much higher. But apart from trusting their crypto savings, other problems remain: lack of anonymity, account blocking, hacking, taxation and other legal aspects of cryptocurrency ownership depending on the country of residence. New decentralized exchanges can solve all these problems while maintaining anonymity and security.
