Gisele and the Dollar

The press is giddly over the demand of supermodel Gisele to be paid in euros rather than dollars.  She does not trust the dollar to be stable and wants to eliminate currency risk in her huge salary payments.  Is this the beginning of the end for the dollar??  She realizes that, like it or not, she is a currency speculator.  She could always hedge her dollar bet (diversifying a bit) but she has chosed to beat on euros instead.  She, of course, would be better off to diversify.
