I really liked your post. I think bots can be really helpful to make your articles stand out from all the posts that are worth around 0.01 $. Especially when you have low steem power and few followers.
I have to agree with @yallapapi about the evolution of the post value. The value will not go up much over time once you have invested. On the other hand, if you invest so much that your post makes it to the trending list, you might get a lot of visibility and new upvotes from people.

Have you had any problems with downvotes with this strategy?
