It's a foolish idea to short gold on the eve of a currency crisis. Gold went up 1812% the last time this happened. You'll be paying through the nose if you do it with $GLD since it's hard to borrow. You'll get IV crushed if you do it with put options. The smart way to profit off gold's fall from grace is by selling futures each time it hits a new high and then closing your position quickly after the inevitable ~50 point pullback. Markets can be timid. They sometimes price in new information slowly and reluctantly.
