20 billions of cash is peanuts compared to trillions of digital fiat.
20 billions wasn't enough to sustain a single state during the COVID scamdemic, let alone the entire US economy.
20 Trillions in USD are roughly 20 Billion in Euro. Amounts in the US are blown out of proportion.
The made it through, that is what matters, numbers in that dimension only scare people with a closed mind.
Its just a number. Get over it.
People in the 3rd world can save in US$ which is still way better than any crypto.
As much as I like to receive coins (Litecoin) most of my clients are not used to the places where they sell crypto.
With the introduction of the bio metric passport, it only gets worse.
