In order to have a creator account, you have to be a content creator (Web site, blog, YouTube, etc.). Tipping yourself isn’t recommended (other than once or twice as a test of the system) because it can trigger Brave’s fraud detectors and get your creator account suspended. And Brave takes 5% of the tips as a fee.
