RE: What if we used the SBDs created every day in the DAO to buy and burn STEEM?
I was referring precisely to the domestic market. Suppose a person has in the market an order to sell 10kSTEEM.
Let's suppose that currently the heaviest selling order in the internal market is 0.08SBD and the amount of SBDs in the DAO is enough to buy 10K STEEMs at that price, but the news spreads that this will be done whenever SBDs are available, then the shrewd seller withdraws his order and places it at double the price, as we are going to buy as soon as the SBDs arrive we would be buying and burning 5kSTEEM instead of 10K.
If on the other hand we set a gradual price target we can set buy orders instead of taking the sell orders, and gradually increase the price of the buy order as the price consolidates, that would burn a larger amount of STEEMs with the available SBD than if we just go and take the existing sell orders, that's what I meant to express.
But it's just an idea, I could be wrong! Or there could be better strategies of course.
In my opinion, the way to do it would be just a continues flow of sbds to internal market buying all steem available on the ask. As this service is continuous it would be difficult to game, just one continues buying of steem available on the internal market. The internal market is mainly run by bots that are continuously replenishing their supply of steem as buy orders take them out, and this replenishment of steem eventually comes off external exchanges. If things get mispriced on the internal market vs the external markets then users will likely arbitrage the difference to keep the prices close.
