How does that compare to the market depth of actual currencies or commodities? BTC, being objectively worthless, must be much more sensitive to people wanting to sell I'd expect.
There's also other debt that the US government provides in USD - which provides value as well, in the form of bonds.
BTC has no such driver of wealth. Except perhaps money laundering/transfers without AML provisions.
That's demonstrably false, because countries like Zimbabwe and Venezuela experienced hyperinflation (the complete devaluation of a currency) in spite of the fact that their governments were still forcing people to pay taxes with those currencies. So clearly that alone is not enough to provide intrinsic worth to a currency.
