If the majority of the speculators who drive the price are not miners (which I believe to be the case, especially during bubble conditions,) how is jiggering with the mining parameters going to influence their perception of anything? I have trouble making sense of this.
Its an issue of supply vs demand, we already have a network that fluxuates with the market, all we need is a supply that fluxuates with the network.
Price goes up -> Hashpower goes up -> Mint rate goes up -> price stabilizes with influx of new currency.
Price goes down -> Hashpower goes down -> Mint rate drops -> price stabilizes above cost-floor.
