The biggest problem for Russians right now, is that if BTC remains possible, very few people are willing to exchange BTC for rubles. The Russian currency was already extremely difficult to exchange in most countries, it will be far worse now.
Bitcoin isn't viable right now in Russia, but the point of this post is that it accelerates the adoption of crypto because they remain immune from sanctions. USD is currently the dominant currency on the global market, but the Russians (and Chinese, for that matter) understand it takes almost nothing for the U.S. to freeze assets indefinitely, locking them out of billions without any form of recourse. Sure, the exchanges will be difficult for now, but 10 years down the line you could see massive adoption.
