Why are you getting paid on Fountain?
Every minute that you spend consuming content, creating content, or watching ads, increases the value of the platform you’re using. Think about the ones you use every day. Youtube, Twitter, Facebook, Instagram, TikTok - all of these platforms would lose their value without the time and attention that you give them, but none of them reward you for it. Fountain is different. Fountain is the only podcast app where both listeners and podcasters get rewarded for the value they bring to the platform.

+ I read in their terms they keep 4% above the streaming contributions , those they probably use for rewards after.
