Personally i upvote my content on 50% and it gives me 0.03 cents. If i ever go above 1k power I'm planning to stop so I have more power for my followers. Although 3 cents doesn't really matter at all if one asks me.
Also this kind of disappointed me at first because people are getting paid to have money really :/
