Right now Bidbots are definitely giving negative ROI based on the fact that the system has the belief that the median price of Steem is currently $0.40 even though it's closer to something like $0.30.

That means you will get the amount of Steem paid to you that is as if each Steem is worth $0.40.

That is to say that you'll get much less Steem paid to you than the actual dollar amount shown.

IE

$75 = 185 Steem

BUT

185 Steem = $45

There is no way to get your ROI this way, and before you say something about three day rolling average it hasn't been $0.40 in longer than three days.
