Earn crypto token UPT, for sharing your internet. Token is already on the market ready to withdrawal and sell if someone wouldn't like to stay for a long time but I think that project has a bright future so I would recommend staying for years. But for sure you don't have to wait for any open minet or things like that because it is already at this point and you can mine it with your phone even easier than Pi.
