Hi
Interesting project, but I don't think it makes sense to put ads in the app. If you need money, just keep some of your tokens (I'm sure you did already) and make sure your product is as attractive as possible (people don't want paying apps or apps full of ads). Then your tokens will naturally increase a lot in value. This way you will make more money than with the ads, your app will be more attractive, users and investors will be happy!
