thanks for the answers, while I see two pluses in this exchange. The first is decentralization. The second is to bathe the tokens after the ico at a discount
The typical drawbacks of decentralized exchanges are the limited functionality, difficulty of use and low trade volume. On the other hand, centralized exchanges pride themselves on delivering on all of these aforementioned traits--making them more popular and of course, easier for the average, passive investor/trader to engage with. That said, decentralized exchanges work, they just require the user to be more attentive and well-versed in the inner workings of crypto. Decentralized exchanges are great for the minimalist and security enthusiast, if these traits are important to you then by all means IDEX. You can also look into ox protocol or airswap.
