The difference between bitcoin and fiat is that bitcoin cannot be frozen, unlike your bank balance where the authorities could freeze if you are suspected to be a criminal or involve in any crime.
You're right, and yet you're not, and here's the problem. If your Bitcoin is in a non-custodial wallet and only you have control over your private keys, then no one can forbid you anything, you can send transactions 24 hours a day, 365 days a year.
But what if someone’s Bitcoin is in a custodial wallet, whether it’s a crypto exchange or an online wallet? We all know that most major crypto exchanges are fully compliant with legal requirements, and we also know that at any time the authorities can freeze all funds on these crypto exchanges for any reason - say on suspicion that users are financing terrorism, or engaging in money laundering. So it's not about Bitcoin, it's about how people use it.
What the hell? You create all the problems and then prints notes out of thin air and says now people can relax easily? Well that's what they have been doing from past hundred of years like putting the whole blame on each other but the money printing game continues every time no matter who is in the white house.
Do they have any choice other than what they do? This is their modus operandi and if they give it up, everything will collapse like a tower of cards. Of course, all governments of the world are aware of what they are doing, but it would be foolish to expect them to say,
"Bitcoin is the solution" when it is the complete opposite of the centralized financial system from which their power to govern the world stems.
