I've seen discussion that the Chinese have inflated their money supply much, much more than we have since 2008. And based on their fake economic stats, their currency may be as much as 50% overvalued versus the dollar.
If they truly floated their currency, to end their manipulation, it could tank instead of soar.

IIRC, Japan tried to export their way out of economic trouble back in the early 90's in the same manner and the result was 20 years of recession and deflation. My point is that Trump should be focused on taxes, regulations, unions, and lawyers, rather than currency. The former are better understood and more likely to help our economy, which is what he wants to do.
