Not only that, but I don't think the Russians really understand western thinking at this point. Even if they get everyone to believe these allegations, so what? It doesn't change that Russia started the war, or the killing they've been doing in captured territory.
"The Ukranians said bad things about Russians". Of course they did, the Russians are literally trying to kill them.
I can't believe they won't just use Bitcoin. If the EU weighs in then Bitcoin would probably get much more stable through sheer inertia. "But then they won't be able to control it" I hear you say. Good, Bitcoin not being able to be diluted by any one government to try and tamper with the economy is one of its upsides. Slower economic growth is a perfectly fine tradeoff for not having 10% inflation year over year like we have the last few years and economists are basically the modern version of oracular priests reading the stars and just as reliable.
