The UI is very easy to understand and use. It's not too complicated, but it also isn't too simple. I like that you can trade multiple cryptocurrencies at once. You're able to trade both ETH and ERC20 tokens. This makes it easier for me as I'm looking for both ETH and ERC20 tokens. There are some other exchanges where you can only trade one or the other. I haven't found anything I dislike about this exchange so far. I like how they have an API that allows you to integrate their service into your own app. They also have an open source library that allows you to build your own application with their API. This makes it much easier than if you had to write everything from scratch.
