Thanks for your reply. Having been on Steemit I do see why bid bots can be profitable to the bots especially when many times the bids are worth more than the vote. But lets say a bid bot says I will only accept bids up to 50% of my vote value well then in this case the bot would "loose" money as it could have just voted for itself with full value. To me if a bid bot is really trying to help minnows or promote good content then it should not take profit and put such a limit to what bids it takes. But in this case people would just be at their computers trying to get in a bid as early as possible which is what i think is happening to MinnowBooster upvote service now.
