As you know, the entirety of the Western world has been hitting Russia with an increasing number of sanctions. SWIFT, VISA, MasterCard, and so on. But, could crypto be the tool that helps Russia mitigate the effects of these sanctions?
I don't think so.
1. Most of the Russians cannot use the banks/cards much and the rubles are getting worthless: not much of ways nor reasons for selling them bitcoin (why would anybody accept rubles for bitcoin?!)
2. Russian whales have anyway a lot of money stashed outside Russia, probably in EUR, USD, CNY, stocks and so on, probably not (or no longer) under their own names. They can easily buy/sell bitcoin under others' names if they want to.
3. Many countries still want to buy oil and gas from Russia, no matter what. So, in a way or another, the money still flows.
As I said in another place, this "crypto helps Russia against sanctions" is imho an over-hyped unrealistic story.
