Call me a dreamer. Call me a contrarian. I still believe in bitcoins.

The collapse of Mt. Gox — and the evident disappearance of perhaps 6 percent of the world's supply of the virtual currency — hasn't put me off at all. And even if I'm wrong, and bitcoin fails, I'll probably support the next digital currency.

The reason is simple: For those willing to take the risk, eyes wide open and fully informed, money without government carries a certain appeal.
