there are some things I want to ask:
1. Is there already a trading application for your project on iOS or Android?
2. I still don't understand about spot trading and margin? what is meant by spot trading and margin?
3. and what is an anonymous instant exchange?
Regarding the first question, I can not answer you, I did not find this information.
And on the second and third questions, I recommend that you read and study the Whitepaper, where you will find the answers to these questions.
