@krnel was a minnow once too. I am a Krill now, lol. If you are only here for money, you won't receive the most valuable thing Steemit has to offer, which is community.

Consider that you can cast ~10 votes a day, but if you attract 10 followers, they can cast 100. It is far more profitable, even only in terms of money, to cast your votes for others, because they have far more votes they can cast for you.
