For anyone wondering how the US could pull this off, converting gold reserves into Bitcoin seems like a no-brainer. It’s a smart play, diversifying their reserves while potentially becoming the largest Bitcoin holder in the world. If they actually do this, they’d dominate crypto reserves, which is a massive flex on a global scale.
I am sure this statement is his personal and not official. It's more like a suggestion about what he feels about American government should do. I am sure that American government wouldn't spend 90 billion to accomplish it. If they ever decide to own a great percentage of Bitcoin supply, they will do it by confiscating from various companies under false charge of money laundering. Trump alone can't/won't make decisions on such kind of purchases.
It's great that powerful people are showing great confidence on Bitcoin. But it's far from reality to be honest!
