I have been analyzing how to approach the strategy of using upvote bots for profit when posting. I have determined that you cannot bring in a consistent stream of income by taking this route. You can make money intermittently doing it, but I would not look for a steady stream of income by using this strategy. The rewards can be great 15%-20% on posts, and you can get on a hot streak if the steem price stays flat or if it rises.
The steemit price will fluctuate and that will determine the profitability of a post more so than if your upvote percentage was high. Take a look below at the difference two days makes when you upvote a post and the steem price drops.
That's a drop of $14 in two days. I will take a loss on what I spent on upvote bots unless steem goes up considerably in the next 5 days. Be cautious with how you approach upvoting posts for profit. I will still use upvote bots but only in the most advantageous situations.
