No one has said anything about "stabilizing" anything. What they mean is that they will update the price feed of STEEM and SBD which has nothing to do about stabilizing anything, but will work to provide an easier view on the internal market about the prices, i.e. the prices will be showing in SBD to STEEM as opposed to STEEM to SBD. So instead of seeing "0,36", you will see "2,72" to make it easier for people dealing on the internal market.

SBD is now trading as a stand-alone coin because of a ton of new traders going into it and there's nothing anyone can do about that, and neither should they; anyone wanting it come down is a complete nut and should probably seek professional help.
