It is no problem. The only condition is trades. That's why we need owner to contact us and guarantee anounce to community. We don't take any fee for adding currencies.
I don't follow, what is he asking for? "The only condition is trades." and "guarantee anounce to community"
I think he means that he don't want this coin if no one gonna trade it, therefore he wants you to contact him and maybe add his exchange on the first page.
