If you look at the value of USD vs gold you can argue that the collapse is ongoing.
In that case, you could argue that gold was collapsing from 2011-2015. I would say both are exaggerations.
What is probably really happening:
U.S. Bond Markets Are Driving Force Behind the New Gold RushNear-zero and even negative yields in the US bond market are driving investors away from the USD. Meanwhile, the combination of Fed QE, fiscal stimulus, and inflation fears are driving risk assets like precious metals, equities, and BTC to the moon.
You can do the same analysis with any other currency, the USD is losing value over time. Since the FED has shown no intention in stopping printing money (especially int hese last few months), one can assume that this situation will not change in the near future.
