There is a lack of decentralized exchanges. It would make sense to have much more of them because of the nature of bitcoin and crypto.
or the lack of good and easy to use decentralized exchanges. Personally when I first used EtherDelta, it was a UI/UX nightmare. If you have to do a Google search on a exchange's functionalities then the UI/UX isn't noob-friendly enough. Hopefully Binance's decentralized exchange will bring out something good.
