If crypto is a “currency” and arguably it is when you have something like sand coin being used as a currency in its own platforms, then Bitcoin is equal to USD.

Fiat can be printed limitlessly but Bitcoin price per coin going up is pretty much equal to printing. So there really isn’t much difference between them.
