Here is a future scenario where the dollar collapses. The timeline suggested in this video seems too tight.
It reminds me of that quote from Mark Faber:
I am 100% sure that the U.S. will go into hyperinflation. Not tomorrow, but the problem with the government debt growing so much is that when the time will come and the Fed should increase interest rates, they’ll be very reluctant to do so and so inflation will start to accelerate.
