BarterDEX is a decentralized cryptocurrency exchange that supports atomic swaps. The exchange now supports ERC20 tokens and more than 66 of these were added today. Over the past few years, there have a massive growth in number of cryptocurrency exchanges but most of them are centralized. While the centralized exchanges appear more convenient to users for buying/selling cryptocurrencies, the coins stored on the exchanges are fully under control of the exchange and not you.
