I think that the color of the design is secondary, the most optimal is the choice. In a centralized exchange, speed and liquidity are important, and the color of design is a rush on the curtains. In order not to slow down, and the glasses were full, that's all. Well, the ability to disable the chat, if at all. I believe that if opening in a month, then the engine will be ready or completely made from scratch?
In the picture there is a button similar to the chat. Means chat will open by the button. Very comfortably! Design is good. I hope for the technical part they will be fine!
