This makes absolutely no sense. Why would banks give up their gold to buy Bitcoin or cryptocurrencies? They could simply buy cryptocurrencies with their cash without compromising their gold...

I remember a senator had an idea for the United States to sell part of its gold reserves to buy Bitcoin, but the proposal was rejected. I don't think banks or governments would give up their precious gold for cryptocurrencies. If they were to buy Bitcoin, it would make more sense for them to give up their inflated fiat currency, not their precious gold.
