Hello, at the moment Brave teams are really busy working to keep Brave privacy and an ad-free browsing experience.
Sadly, I'm not sure I have enough knowledge in hive to think about how this reward program could be done.
One way to do that could be to comment under a post, and all the rewards from this comment will go to the people who read this article.
Thanks for the suggestion, I will keep it in mind and see what can be done with it.
