Yeah... say what you will about FIAT currencies, but at least they can be used as currencies. I always chuckle at people who insist their transactions on exchanges are secret. With the "Know Your Customer" rules, FINCEN knows what you're doing (or at least has the option of looking into what you're doing.)
It's funny. I drive a FIAT, and started capitalizing it ... But yes, in this instance I was talking about fiat currency, not FIAT Currency, a little known sportster model sold in the UK market for one year 1968.
