I upvote my own posts at 100%.
I also upvote almost every other post I support at 100%, and I try to create content I would be willing to 100% upvote if I saw it from someone else. I never use votebots. All the Steem I have was earned by getting upvotes from others, rather than by paying cash or trading crypto. And when Steem spiked last time, I was starting to think about reducing my self-votes because it started to feel sketchy for me even as a small dolphin.
