If any stakeholder, large or small, wants passive income they should support curation projects like @curangel. Or if they want a better ROI, then @ocdb should fit the bill as it gives 90% of vote value to delegators and 10% to supported authors who have been curated by OCD and manually added to the whitelist. @ocdb uses its downvoting power to combat abuse, too.

The larger your investment the more of what you invest in should reflect an effort to increase buying pressure on STEEM. What bid bots with a non-negative ROI do is completely ridiculous: pay people to advertise in Trending. That guarantees Trending to be filled with garbage nobody wants to look at, driving away eyes from it and causing Steem to be shunned by investors.

Any earnings in STEEM are purely illusory without an increase in the fiat price that exceeds STEEM inflation.
