Previously traded on the Delta. However, it had very poor functionality. And often braked. Today is the best solution exchange IDEX
I also do trade on etherdelta and forkdelter but it has been long I used them to sell tokens. The two decentralized exchange that come from each other do discourage trading to keep distance because of the "functionality " I think I do prefer to used a centralized exchange more than decentralized one this days.
So far yes that's one of the dex with volume. After the hack of binance, a lot of users in the forum are recommending to use DEX for safer funds. One that I have been using before was the WAVES DEX, it existed before IDEX but failed to generate more volume. I don't really see why DEX will be used often if there ain't no volume to it.
Many exchange always have the same reason their assets and market hacked, I can't trust it because how come an exchange market can be hacked with higher security level? what for giving reason their market hacked and why not give back investor money in their exchange account, always not responsibility owner of exchange market want giving back investor money.
