I believe, what you mean here is 2021 not 2020 - "Our first partner stores will open in Q4/2020". Real world use case will help any project to sustain the interest of users. Because if there's none, traders will just hop from one project to another. But if you have active use case, they will be encouraged to say because the possibility of increasing its value is high. So waiting what merchants will be on board on this project.
