How post payouts are affecting bid bots ROI

Today I had a long conversation with @brandonfrye as to why 10% ROI is not really 10%, but way less. Since I already ran the numbers, I thought, I will share those with my readers as well and make a few cents out of it too.

The way post payout used to work was, you get 50% in SBD and 50% in STEEM, but if you have noticed, that has changed since last month. That is because of dept ratio. When it crosses 3.5%, steem reduces the number of SBD printed and gives out part of the reward in liquid steem. As of right now, SBD print rate is at 62%, which means you will receive 31% (52*.62) in SBD, 19% in STEEM and 50% in SP. SBD is always treated as 1$ value by the system, irrespective of its actual value, but when it comes to steem, it is awarded based on price. Because of this, we are getting less money then expected.

This is an analysis I did on one of the posts that was voted at 10% ROI but in fact, it is below 3% ROI. That is the reason I have stopped using bid bots for now. I use it in a very narrow scenario, and if you have read my other posts, you would already know.

Having said all that, I do want to give a shoutout to @therealwolf 's @smartsteem and @smartmarket bots. They have modified their formula to take care of this change in post payout. As fas as I know, they are the only one who have made that change. You can read more about it in this post.

Also, I just noticed that @brandonfrye has updated his minimum ROI to 10% and maximum to 15%. Appreciate his effort to create a fair bot.
I will be using these 3 services until others are fixed.
I will maintain a running list of all the services that fix their bots to reflect new steem payout changes.

Fair bots to use:
