In 1978 the IMF wrote gold out of the monetary system. Countries weren't allowed to peg their currency to it anymore. Central banks bought over 1,000 tons of gold a year anyway, three years in a row from 2022 to 2024. Central banks now hold almost as much gold as they did in 1965. So the 1978 rule was meaningless and central banks stopped acting on it a long time ago. I'd bet central bankers keep calling bitcoin worthless for years after their own banks start buying it.
