I like very much your new bots stats which gives another view to the problem or opportunity.

On my experience and thinking I see no way how to make money on Upvote Bidding Bots, except getting uplifting by the Bot weight to increase probability of been seen.

Steemit procedure for payouts always will return 0.375 of the Upvote, and they are never ever that high.

Theoretically, average number of Upvote Bidding Bots users should be declining as they realized that game is not for positive ROI
