Every now and again there's an article that says the dollar is gonna lose its place as the dominant global currency. Sometimes people say cause of the rise of China, sometimes people say cause it's tied to Oil and Oil isn't gonna be around forever, sometimes people just kind of wave their hands and say cause nothing lasts forever. I don't know how accurate any of those predictions are (though I put most faith in number three, cause really, nothing lasts forever), but does something like this help or hurt the dollar on the global scene? Edit: For clarification, I don't know enough about global currency either to know whether or not it's really all that important who's on top. Though I'm assuming, being an American, having the American Dollar on top benefits me in some ways I'm unaware of.
