lol, why do this when we already have Bitcoin?
Bitcoin is too volatile for people & businesses to budget their expenses.
BitUSD works great though
http://bitsharesblocks.com/assets/asset?id=USDBitcoin, BitShares or BitGold & BitSilver should be good for hedging against inflation.
Though I have to say POW is looking weak these days. LiteCoin especially can't sustain 30% inflation in a bear market.
(Ripple is no good as it's centralised with over 60% of supply controlled by the founders imo.)
