We know bitcoin is deflationary and freicoin is essentially inflationary. Is there any altcoin that perpetually creates coins and aims to hold price levels constant so that simply holding coins should theoretically produce no net benefit. I would assume the monetary supply would grow with some kind of measure of economic activity.
I believe the eMuni system basically has this concept in mind - there would it seems be a small amount of "lag" due to elasticity , but essentially it is aiming for this.
