Who are these masses of people exfiltrating their money from these countries with crypto? They seem as yet more theoretical & annecdotal (and even few of those) than actual, especially since there are still normal traditional finance ways for individuals to do this sort of thing. Also any of these hypothetical people that put their money in crypto just lost a significant chunk of their life savings.
