i think he is a clever investor, bringing daily charts (5-10) and more or less shows possible patterns. he has a world full of SP, which made his votes 60$ heavy. Pretty unsure if it changed but he has a 95% selfupvoting. Don't like it, but to be really honest i don't mind it. He is playing the game. 18k$ the month is totally fine, since he invested a lot, which brings some attention to my point above!

Thank you. I was told there is nothing wrong with self upvoting as long as you get more than 0.03 for your self vote, otherwise it is just a dust. But I think I am beginning to understand now that concept of self voting where you reward yourself more rather than rewarding the person who owns the post.

There is nothing wrong with it in my opinion, but there should be a good ratio between both. Steem is a community thing so everyone should be as supportive as possible. Other reason might be the downvote festivals starting to kill your earnings

Yes, I agree. There should be a balance so that more minnows will be able to progress that they may be able to help other minnows in the future. Similar to the concept of food chain but here on Steemit, smaller fish need big fish to somehow survive through their upvotes.
