You used the word “safe” . seems when Biden seized foreign assets it made some jittery and they are playing around with alternatives.
Well its not safe to lots of people. But most American money is safe. Not sure where else to go. No other major currency is up verses the dollar. Gold is up, but the transaction and storage costs are very high, same with Bitcoin. I guess GLD (the etf) has been profitable. except for two months in the recent past.
