re: Bitcoin is a Ponzi scheme—the Internet’s favorite currency will collapse.

I wonder when Paul Krugman is going to weigh in on bitcoins? He can hypothesize about a single bitcoin being worth $1 trillion and the Satoshis worth $10,000 and further fractional units worth lesser amounts. All the U.S. government needs to do is buy a few hundred bitcoins and hold them until they are worth $1 trillion each, and we can pay off our national debt. Meanwhile Congress can deficit spend to its heart's content.
