How much is REAL transactions though ie BTC replacing Fiat and buying actual real-world goods and services (ie not gambling, BTC securities, ASICs or SilkRoad)?
Where are the stats on that, or does no-one actually want to see whether there's any real BTC economy out there........!
Pretty sure there's plenty of people wanting to see stats on that, but other than BTC-based companies releasing their revenue numbers there's no way to find out. With BTC address not tied to any specific company or person it's impossible to distinguish securities transactions from a real-world purchase from a key-rotation.
