I despise bidbots too. I have found about @ocdb a week ago or so, as someone mentioned it's a great initiative.
Doesn't work as bidbot for me (I rarely buy a vote anyway) as I'm not whitelisted and no chance for that... as no whitelisting process. I'm out of the circle.
As with other bots, owners get 97% of rewards, as you have calculated yourself.
The bot is getting 86 from me + 31 from the reward's pool = 117 STEEM
I am getting 90 from the reward pool - 86 i paid to have the privilege = 4 STEEM
Maybe there is no escape from the law of those who have a lot will easily get more, those who have little will loose a lot of that little
- Unlike other bidbots @ocdb might be more fair in distributing 97% of it's profits. I have just delegated loads of SP (100 to be exact). I will monitor.
Edit. If @ocdb owners keep bids for themselves and distribute only curation rewards to delegators, it's not worth to delegate. I will try to learn more and will monitor for a few days. Seems not a good choice this delegation I've made, as it might be trully beneficial to only a closed circle of people.
