You know Etherdelta was one of the most exoteric and favorable DEX. Most of the exchange is now fully centralized and required KYC, Sometimes KYC is very unpleasant, DEX will be very useful for those who do not like centralized exchange. Dex still has a lot of flaws and is a bit confusing to use. If these shortcomings are solved, people will be more interested in using DEX Network.
I used to like IDEX, as well as Etherdelta or forkdelta for day trading. of course, the people on this forum are familiar with the exchange. but currently, I only use Binance DEX for day trading. But it does not last long. I think its popularity is not as popular as it was when a lot of tokens ended up migrating to the Binance blockchain.
