Unlike bitcoin, fiat currency is controlled by a highly centralized system of trust making it unpredictable and unstable.
For example, no one predicted FDR confiscating all the gold privately held by Americans in the 1930s.
No one predicted a neverending war in Southeast Asia started and executed by US Presidents.
No one predicted Nixon suddenly taking the US off the gold standard in 1971. It was known as the Nixon Shock.

These were all black swan events that came out of nowhere. If there is one thing the markets do not like, it is instability, shock and chaos.
But throughout its history it seems the US dollar fiat system has been a neverending parade of all those things.

No one (or almost no one) predicted the near collapse of the world banking system in 2008.
The fiat banking system was only rescued by trillions in taxpayer bailouts.
Not a single banker or politican responsible for that massive scam ever went to prison.
So what it is stopping them from doing it again? Nothing.
Because they know the "Too big to fails" always get bailed out no matter what they do.

The US Constitution was a revolution in world history that promised fairness and equality.
For the first time in history, the promise of a society that was "governed by the rule of law and not by men"
as John Adams famously wrote. At least that was the theory.

But the problem is, you still need men to enforce the rule of law. Which humans themselves have always been the greatest flaw,
the fly in the ointment, the weakest link in the chain. And over time the men and the systems they created became more corrupted,
more unpredictable, more unstable. The people in power can simply ignore the rule of law and do whatever they want.

But imagine if you had a mechanism that could bypass human systems and their highly concentrated, centralized control.
You could avoid the age-old problem that has been plaguing human civilization for millennia.

That is the revolution of Bitcoin, because no controls it. Not Trump, not Biden, not Buterin or Hoskinson.
It is trustless. Bitcoin is controlled by its immutable rules and code, not by the whims of a politician, a king, or CEO.
As we have seen over and over again, the fiat economy is always one Mad King away from total collapse.

Kind of ironically, King Trump's endorsement of bitcoin helped him get elected. At the same time,
the total chaos Trump has created could be the nail in the coffin for collapse of the US dollar,
the straw that broke the camels back. It's actually funny. I don't know if I should laugh or cry?
The US dollar is a flimsy house of cards that may come crashing down any moment.
