Trade is FX. Protecting USD status as the worlds reserve

One of the most important points in the new "Trump System" of doing business, is that of the US Dollar, which currently is used by world's central banks as their reserve. Also, it's used by peasants in many parts of the world including Russia - as an alternative to their domestic currency. Practically, there isn't a clear alternative to the USD for the time being, with China's economy mostly built on ponzi frauds - but it should be noted by all that it is only a recent phenomenon that the USD is the world's reserve currency, and it can change with the blink of an eye.
