Note to anyone who's designing cryptographic currency 2.0: stabilize the price next time. It doesn't have to be tied to USD but it should be tied to something. Control over the supply automatically gives you control over the price, you can peg to whatever you want.
Global GDP futures perhaps? It would be interesting to have a currency worth a particular percent of global output.
That part of the point of BTC though, AFAICT - no price control, no supply control.
It appeals to libertarians for this reason. Doesn't appeal to me because I like stability in my currency and am happy to have central authorities that try to ensure that, but it appeals to libertarians.
