Solid research :)
Fact #2: 25% of the rewards on any post go to curation.
Shall we assume that majority of those 25% will end up in "hands" of bidbots (pretty much fully).
Are Bid Bots profitable for the users?
I can only share one tip. Try to use bitbots on sundays. That's when it's the easiest to make some profit. On weekdays it's the hardest because many others will place their bids as well.
Cheers, Piotr
I agree that with high Steem Power the Bid Bots earn a large portion of the curation rewards
