im not sure your numbers are right. i just paid a bot with the 10% roi .05 SBD and got an upvote with the value of 0.116 where the bot recieves .004 in curation rewards.

are you sure you arent missing something or that your calculations are correct? because according to this post is should have made 0.005 in profit not .064

for example I will upvote this comment wit a bot that fits your criteria.
