Exchange platform is not a new idea so you must have unique features that you can offer to the users and add it on your main landing page to attract more people to use your platform. I do like your idea of getting feedback on this forum before launching your project but you must know that new exchange these days have trust issues so I was thinking if you will publicly show the team behind this project?
It seems the concept of exchange is currently one of the ideas to build a cryptocurrency startup project, I think this team needs another concept that is more unique than having to build a project with an exchange platform, I don't want to be pessimistic about what they are doing, but in reality right now many projects that have an exchange platform cannot compete with other projects, we know that if an exchange platform has to have a large amount of funds, a reliable team also requires unlimited development, and promotion so that many startup exchanges that ultimately fail before developing.
