Best exchange design [on hold]

I suppose that a lot of people have already looked through cryptocurrency exchanges. All of them have similar design and are... unclear. Whenever I enter such a crypto exchange I get confused. It is a mess of tables, pictures and information stuck in one place. Could you advise me what features/options and design exchanges should have to be user-friendly and transparent. I would like to create an exchange website that understandable for nonprofessionals and practical to use.
