I have been thinking a lot lately about why the central bankers are allowing Bitcoin to continue with only minor resistance.
Central bankers aren't "allowing" Bitcoin, Bitcoin is permissionless
in the future, maybe central bankers and government can allow bitcoin and maybe they will makes bitcoin legally and can be used by all people in the world,
They can't allow it like they can't forbid it. Nobody can forbid bitcoin, really.
Govt can make laws that punishes the use of crypto, but that is a totalitarian regime.
