they couldn't care less about the war. they always had to his their money either from ru itself or their host state's irs. sanctions or not make they buy Bitcoin so they can sell it for usd with minimal hassle.
nothing of this is news because of the war. and before btc it was money purchase of real state.
BTW, if discussing Bitcoin is something HN frowns on I will delete this. I've never seen a policy or preference expressed on this topic.
