The article only mentions how it benefits Russians, but omits the fact that almost any Ukrainian or Ru opposition donation page has crypto addresses on it. The money flows both ways, the way it was intended. Also, Russians laundered hundreds of billions through Baltic banks (Danske Bank, Swedbank etc) with oh so real AML officers.
Crypto is actually net negative for UA if it is what keeps Russia going. If crypto vanished overnight UA would still get aid through legal channels while Russia would be crippled.
Btw I think those bank laundering events you mention date to before the war.
