Imagine how many police officers have done the same with fiat and gotten away because of how anonymous and untraceable it is. And yet people, especially politicians and regulators have the gall to call Bitcoin money for criminals.
This is absolutely true, fiat can become untraceable when it is in the physical form and even today USD is the most used currency for illegal purchases on the domains, yet the same government claimed bitcoin is for criminals and they can hide if we let the people to use bitcoin as money.
In reality, they don't care about being used for illegal purchase but whether I can make money from it, with fiat they can just keep printing more and more so they just create it from nowhere but bitcoin isn't possible to create like that which scares the banks and the governments.
