This is awesome brother, you got it started. I think this is great! I just saw your comment from your post yesterday about this and replied. This is why I think this could be a huge win/win:

To the right parties, depending on their investing goals, this type of arrangement could be quite beneficial for both.

I see SBDs as a liquid version of Steem. It's supposed to be pegged to $1 US dollar, but in actuality, has been trading like it's own crypto currency. They've been extremely profitable so far with their trading price being as high as double their implied value. Now that the SBD price has fallen more in line with it's implied value of $1 US(it's trading right around $1.07 right now) some could see more value in holding SBDs over Steem or Steem Power as a short term hedge against a downturn in the price of Steem.

If your goal is simply to acquire more Steem or Steem Power in the short or long term, selling SBDs for $$ to increase those assets would be beneficial to you. We all have different investing goals, and this I think is a home run of how we can accomplish those goals WITH 0 FEES and done in house on Steemit. In my opinion, this increases the value of the Steemit platform just that much more. It's literally like having access to a trading platform but all transactions are peer to peer and at no cost. Kinda brilliant! Resteemed!!
