Warren Buffet is a spent force, creatively, as he can’t see anything worth investing in, with millions of options.

I guess drinking all those cherry Cokes gave him diabetes type III and drowned his brain in insulin and glucose.

So what’s the logic of “investing” in the US Dollar over everything else?

It would seem like a dumb move.

Banks are planning to do a massive shift to Central Banks Digital Currencies (CBDCs) and will shift to NEGATIVE INTEREST RATES for fiat, leaving positive interest rates exclusively for CBDCs. This intention is part of the motivation for the SEC to viciously attack staking agreements in crypto, to remove the closest alternative using government as hired muscle to blockbust.
BRICS has their own bank and has a plan to dethrone the US Dollar.
Saudi Arabia is accepting currencies other than US Dollars for oil purchases.
The Federal Reserve is still planning to continue raising interest rates, which means an increasing risk of a reverse, which will reduce the relative value or cost of US Dollars.
