Previously traded on the Delta. However, it had very poor functionality. And often braked. Today is the best solution exchange IDEX
One vote for IDEX, this is probably the best and most stable decentralized exchange I've experienced and used for a long time. Volume volume and reputation, it has met enough and brings ease and satisfaction from a large community. DDEX also seems better. But we are in the most modern technology environment. Certainly there will be better DEX formed. BitdepositaryEx seems to have a good testnet version.
