The “Bitcoin Sign Guy” sitting directly behind Janet L. Yellen, Chairwoman of the Board of Governors (a Federal agency) that oversees the privately owned Federal Reserve System of (central) Banks, during her testimony to the house financial services committee, holds up a sign that says, “Buy Bitcoin.”  The sign also contains a URL from which to purchase the world’s first de-centralized, crypto-currency

       Postscript: Over the course of the next two days, the URL made nearly 15,000 “dollars” in Bitcoin sales.
