It is in the process of replacing fiat as we speak, but these things take time. It's going to be another decade or two.

And fiat is certainly not "moving forward" whatever that's supposed to mean. The only thing fiat is doing is being debased by constant money printing.

Bitcoin is not "standing still" it's being adopted by people, companies, families, corporations, annuities, trusts, pensions, unions, and governments.
