Why this information

I am providing this information for those who would like to use bid-bots or other voting services to upvote their posts with unique high-quality contents. They can use this information to determine at what point it is profitable or not in making a bot purchase.

One of the common mistakes people make in using bid-bots or other voting services is thinking that as long as they get $1 vote value for $1 SBD bid or $1 Steem bid, they are breaking even. However, in reality, it is not! (Up to 25% of vote value goes to curators and half of the remaining is divided by steem price.)

Author Reward = 37.5% of vote value in SBD + 37.5% of vote value in Steem (divided by steem price)

Please see table below for ROIs from 1.50x to 2.75x vote value.
