no you are right. This is either to you or others. You can upvote the content you create or make money with the curation rewards (which become substantial as you power up more and more). I figure that if you combine the votes coming from other, one would get at least 7.5% a month. But it is far from easy to calculate since one cannot upvote his own post (1 a day) and 9 comments a day only without having some for of backlash for not spreading the love.
