This doesn’t really make any sense. Bitcoins wild fluctuations make it terrible for a currency and its fluctuations have only gotten worse over time. It’s just a speculators game. If it became a universal currency, you would just convert whatever you have to it. There’s really no path for bitcoin to become a universal currency, because that would require stability. And there’s no path to stability with the current speculation interest. If the speculation interest dries up it would plummet, but that would just continue the cycle. It won’t ever stabilize unless it crashes and people stop caring about it.

What drives the valuation is pure speculation, partly by massive vested interests, and then of course by the masses of cultish believers who own a couple coins and are in on the Ponzi mania. The same things that excites people in Amway.
