You know the sad reality is that I'm only just partially joking about their reasons for "concern". Seriously, you have to admit that colonizers being "concerned" about the economic situation of those they oppressed, exploited and colonized for centuries is some truly shameless hypocrisy.
The Venezuela and Iran examples are just two in a loooooong line of examples of this type of economic dictatorship. You can either choose to buy into their fear campaign and give up on Crypto, or insist you are many steps ahead of the rest of the world and that these are just the effects of something revolutionary which you are in on. As far as I'm concerned the choice is entirely yours, now as far as they're "concerned", well, just let history speak for itself.
