I have not heard about the addition of the second exchange. It seems to me that only after launching the application it is necessary to expand the number of exchanges for better access to them by users
of course the second exchange could enhance the reputation of the project. I think that this requires additional costs. It is likely that the team is not ready for this.
Perhaps, but I read that the project raised enough funds for the development of the application, but it is unknown what part was allocated for the marketing campaign and increasing the popularity of the product.
