The Atlantic has slapped together a Bitcoin Collapse Calculator that shows you, in real time, how much value Bitcoin has lost since it hit its high on April 10th. Hilariously, they even show how much the Winklevoss twins (who just yesterday were referred to in the New York Times as "Bitcoin moguls") have lost. At the time of this writing, they're down $21,017,340.59 of what I assume is their dad's money. This is a tremendously satisfying way to spend a few minutes.

UPDATE: Oh, good. Gold is rapidly losing value, too.
