Q: Who's paying the most for bidbots?
A: Those whom care more about trying to get to trending than about ROI

As much bidbot mastery as I gained during my time here, I find it hard to imagine myself getting close to these sums over an entire week spread on all bidbots which I use over all bids.

How do these accounts have so many SBD and STEEM?
At least one of them belongs to a whale whom used to and may still operate or at least delegate steempower to a big bidbot or two.
I suspect that more of these accounts are related to bidbot owners whom cycle their funds through their own bods, stealing their customers' money as a result.
Only a minority of bidbot owners/operators are decent.
Most of the bidbots which I ever checked or tried are scams, one way, another way, or in more than one way.
It does not imply that if I use a bidbot now then it is not a scam.
I keep revealing stuff with time.
I already posted about it in my blog in the past, and may add and update in the future.
