Venmo moves dollars and crypto does not

Country A: person uses government regulated exchange/on-ramp to acquire crypto or mines it.

Country B: person receives crypto and trades it for local currency using a government regulated exchange

Which specific laws or regulations are being broken from which specific countries?

The fantasy is that country A (or B) isn't going to regulate the currency.

It doesn't work to tell the government that it isn't currency, they will just patiently explain to you that they decide that.

You also cannot transfer nonmonetary assets cross border without following regulations. Why do you think you have to declare at customs? https://www.congress.gov/bill/115th-congress/senate-bill/124...

Did you really think that getting around money laundering laws is as easy as converting to nonmonetary assets before transfer?

What jurisdiction are you talking about?
