Price is formed by market, so there is no way for stabilizing the rate artificially. If this was possible, there were no traders on the market at all.
Absolutely. The price is always driven by the market and the Demand: Supply ratios. The point is not to come up with something that regulates the prices artificially but to give more tools to the Community to be more assured of the stability and not merely go by sentiments. That will reduce the vulnerability of prices through 'Pumps and Dumps'.
