@11112011 Gold is still more useful than bitcoin currently. Actually, pretty much everyone in the western world has some amount of gold. You got a smartphone or a computer? You've got gold. As for mining bitcoin, sure it CAN be mined with renewable energy, but that doesn't mean it IS.
@11112011 I'm less interested in the trading aspect of bitcoin. I want it to become what it was designed for: a daily used currency than can replace traditional banking.
