IDEX is the most simplest exchange that have come in contact. Idex is a decentralized exchange built on the ethereum blockchain, supporting erc20 tokens . Another thing is Idex supports the trade of over 300 tokens in a peer to peer environment using smart contracts to relay transactions on the ethereum blockchain.
At the moment, IDEX is the best decentralized exchange, but the liquidity at this exchange is still very low and does not meet the needs of investors. I think most decentralized exchanges have had this problem over the past few years and certainly investors will not like trading here. In my opinion, decentralized exchange is only for shitcoin lovers because this is the best place for you to do that in this market.
