It's very likely. It would be an effortless switch to Bitcoin for Russia and give them access to a currency/network completely invulnerable to nation state controls.
Blocking SWIFT for Russia would be a very, very, very stupid idea because it would precipitate the collapse of the U.S. Dollar. Which, I'd bet, is intentional because the central banks want to push out CBDCs they control and populations are primed to support it willfully (in opposition to Bitcoin) thanks to several years of anti-Russia propaganda. It's a perfect mousetrap.
All Russia has to do is tell European countries reliant on its energy exports that they'll only be accepting Bitcoin moving forward. This would force those countries to scramble to get Bitcoin (if they don't have it already), forcing the price up rapidly.
