I have not had very good experiences with bots tbh (especially since you are subjected to the fluctuation of Steem and SBD). When I used them I remember I invested 4 SBD but only had 3.9 SBD in return (at the very moment I made the transaction, I was gonna get up to 5 SBD plus 1SP, but market prices dropped it).
I think for everyone willing to use them, there must be a good understanding of them, or else it can be counter-producing.
Hope to see what your bid bot will be like.
