I think this is my first time coming across a decentralised exchange launched on the ethereum blockchain. Loopring Exchange is a decentralised that supports the trading or swapping of ethereum and other related ERC tokens. As a decentralised exchange it certainly means that you are in 100% control of your funds which makes it a non custodial exchange. Normally, decentralized exchanges are known to have a low trading volume but with about 11 million USD ( CoinMarketCap) as the trading volume of Loopring exchange, I guess the liquidity here would be very okay. Well, I am yet to trade here because the exchange recently launched it V2 which was using Loopring Protocol 3.6 which was also in beta. While in beta, your funds are under a great risk and this has been made by the developers of this exchange, so for now, I'm just monitoring the exchange until it is fully launched.
