100 years ago, 1 US dollar was approximately equal to 1.6 grams of gold.

And on the actual US dollar note, it says "The Notes Legal Tender For All Debts, Public and Private" — "This is the legal tender for all debts."
From the earliest Bretton Woods system, the United States defined its dollar hegemony with especially strong gold reserves.
As a result, the decline in US gold reserves compared to global gold reserves led to the Nixon Shock in 1971.
Now, with Trump's constantly changing tariff policies,
Gold is no longer an investment asset but has become a core weapon in the global power struggle against the US dollar and US debt.
Therefore, starting from 2025, an increase in gold prices does not necessarily mean the stock market will fall. Gold is no longer a single safe haven asset; more and more major countries are choosing to sell US debt and instead buy gold as reserves.
Holding gold seems to be a way for us to collectively change the world monetary system in 2026.
