I belive the Koreans have found a way to profit from this. Steem was quite cheap for some time, and I think they must have acquired enough and are now concerned about the value of the money they take out. To me, it's easier pumping sbd than steem, because of time duration to power down. So rather than power down, I feel they'll just allow the community grow the value of steem, while they grow the value of sbd they make from their upvotes and make profits from the price difference.
I don't think sbd would ever go back to its pegged value, minnows and newbies would get discouraged, because they would have to post alot before getting little or no value for their hard work.
