That's a tricky one to answer

I think it probably requires regulation. How a person chooses to use / spend their OWN money is their own business, and if they have relatives in said countries and crypto is the only method they have of getting money to them, they should not be prevented. At the same time, bad-faith actors in that space should not be able to funnel Australian money to corrupt, antagonistic, adversarial and/or despotic regimes and terror organisations, that could be used to violate human-rights and/or be used against our own nation's interests.
