It could also help the Russian people in a time where they have no control over their lives. I think these oligarchs depend more on the global elite social class system than is intuitive. They NEED the SWIFT system, and that is the real attack against Putin. If SWIFT goes down for Russians, it puts Putin into a very tough spot.

Long-term the most important thing for Russian sovereignty is the ability to remove leaders. Russians can remove Putin and install a democracy at any time without anyone's help. But they don't because he suppresses with fear and misinformation. The media is right to criticize any tool, like Bitcoin, that despots use. But, long-term Bitcoin makes it easier to remove leaders. Anyone with internet can use it to say something un-censorable by a central authority.
