Think about the new US law in Congress that want's travelers to declare their digital cash as they pass through the border. They do this because unlike when we withdraw from banks while traveling, withdrawing money through Cryptocurrency is done without reporting it to them, making it so they can't follow our money movements and also cannot freeze our bitcoin like they can with our assets. This creates a form of money that operates without their control and without their oversight, allowing users to move their money without needing permission.

I understand the issue they may have with that allowing users of Cryptocurrencies to not be able to be audited for underpaying their taxes, but that is a byproduct of not having the government observing your money flow.

Any opinions on this?
