The problem is there is too much debt, no trade war can fix that. A debt burden government have always made the one bad choice to dilute the currency to infinity instead of the politically unpopular choice of cutting spending. From ancient China to Roman Empire to Weimar Germany to Zimbabwe and now Venezuela and many in between. That has always been the end game.
So the currency will fail why? When currency is "printed" (created) they dilute the supply, like new shares of the company dilute the value of existing shares. This currency supply inflation leads to price increase by the simple principle of more currency vs goods and services. Once people wake up to the ugly reality of inflation, everyone will try to use whatever currency they have and another round of price increase happens as demand goes up.
Usually there is some devaluation, playing with the units happens before the con game is bust and start again with a new currency.
Ignore the noise and stack up on hard asset that can't be created out of thin air. When the smoke and mirrors fail it is going to look real ugly.
