Totalitarians at the Bank of International Settlements (BIS) suggest that any coin that has passed through a non-KYC wallet AT ANY POINT should be tagged and possibly banned from fiat off ramps.
Fear-inducing rhetoric like this serves a purpose. It keeps people away from Bitcoin. It's what the fiat puppet masters want.
They are telling you that you're guilty by association if you use Bitcoin. They want you to lose trust in it.
And yet, they'd never propose that a $100 bill deposited at a bank without explaining where it came from should be banned from use.
Oh wait. They might.
