Ok, just so people know the other side, Jim rogers and griffin have been telling the "dollar will crash" for at least 10 yrs. Probably more, but I started following griffin and rogers for 10 years. In that time, the stock market has gone up over 3x. Gold has lost value (compared to the dollar). Dollar (dxy) has actually gone up a little bit.
Will the dollar go to 0? Sure, nothing lasts forever. Just make sure you can last until then.
