Hi all. Nicely thought article! We are Hive account@profitvote bidbot owners. Currently we have one of the biggest ROI on Steembottracker, 30% fixed minimum and maximum return (the only bot to offer 30% minimum guaranteed return). We pay out 100% of our earnings to delegators. Our only profit comes from curation rewards that are around 12-15% max. We have 28K delegated SP. We do struggle to attract big stake delegators inspite of having the better business model (both towards authors and delegators) compared to other bots. Our profits do not even cover server expences, but we are still there hoping for the better times for the whole community and eventual steem price increase.
