I can't go into a store and buy a suit with gold, so it's not a useful medium of exchange for me. If gold, or bitcoins, fell out of the sky and into my lap, I certainly wouldn't mind. But given the same value of gold, bitcoins, or dollars, dollars tend to be the most convenient for me.

I don't own gold either.

I can't wait to see the face of doomsayers once Planetary Resources (or other company) starts mining gold from asteroids. I'm sure Gold's intrinsic value will hold up, with the increased supply...
