While we keep seeing payouts getting smaller over time, we also see more content being upvoted which is good and makes good content more visible. The prize pool will get bigger and bigger over time, it's designed like that. There is no point in being stingy with upvotes, it would only hinder the platform.
Thanks for the comment. I believe we all will learn that the lack of upvotes since HF19 is causing the reduction in rewards.
