say more! something that pays you for ads?

I think brave already pays ppl for ads. it’s cool that brave has so many users (still growing) but token seems dead. 

No clue of it’s revenue growth and roadmap also. Would be cool to see it/ someone else replace Google. expand search to email, cloud, conferencing etc.
