ED has inherent problems most in this thread are glossing over. It has a bad reputation because of its terrible UI. But the UI isn't actually that bad. Once you understand how to work their system the UI is actually fine. What isn't is the terrible lag the system has. You spend gas for every transaction unsurprisingly, however because the system has major delays its not uncommon to literally BURN money trying to buy or sell an order only to get a popup that you missed it and the UI just hasn't updated yet.

Spend enough time there and you will literally light money on fire on missed and canceled transactions. Horrible.

It however is a gateway to a lot of new and unknown coins that you may want to access early making it a necessary evil for now.
