Since you posted here on this forum platform and want to promote the exchange you mentioned here, I think it would be better for you to handle it with experienced managers
here on the forum platform like @Logitech Mouse, @icopress, @AB de Royse777, @yahoo62278, and @julerz12.

Because whoever of the managers I mentioned will definitely help you promote the exchange you're talking about here, maybe you have an allocation budget for promotion, right?
