I'm no expert, but from everything I heard in recent years the US $ was over-valued, thus the devaluation of the US $ and the relative strengthening of the C $ was inevitable. So, the question I need to ask myself is why did I leave so much money in my US $ account?
On a related note, what do you all think of the fact that the Chinese are sitting on so much US cash? As I said, I'm no expert, but it seems to me that this gives them a lot of power!
