I invest money into upvote bots on steembottracker.com. So first you buy steam then use upvote bots ,they pay you back after a week in steam dollars and steam power. The steam dollars I reuse on a another post and the steam power makes my votes worth more. So the money you put on to the platform washes through the different currencies. This helps the platform grow, helps me build a following and make a few dollars on the upvotes, and helps people who read earn curation rewards. its a win/win/win.
