Have you ever lived in a county that went through hyperinflation and had to use the USD to stabilize prices? It's because it was the best alternative to a high inflation currency. The USD dollar drove bad money out because it was relatively good to their alternative. Now people have a better alternative to the USD, so they are dumping it for something that is relatively good/better to their alternative.
what? dude that's some serious misinformation you're spreading here
