The dollar has a huge inherent demand in that you need to pay US taxes in dollars. Bit-coins lack that demand but there total value is so tiny just about any perceived long term use creates a huge speculation opportunity.

PS: For comparison WoW gold is a much larger currency.

Is it possible to calculate market cap for WoW gold? Is there way to know how much is in circulation?
