Right now there is still NASDAQ traded "Freedom Holding Corp" (FRHC) originated from Kazahstan with primary business of fueling sanctioned Russian money and doing other shady business in ex-USSR. Everyone knows they mass open accounts for Russia residents remotely and no one cares.
It's not like there are no other banks doing the same, but none of them are owned by US-based entity traded on NASDAQ. SEC certainly wont care until it implode on thousands of retail investors. Going after crypto is far more important.
And there are more financial institutions that have banking licenses around the globe (including US, EU and UK) with primary source of income from money laundering and again no one cares until they grow too big or scam all their customers and investors.
