The European Commission proposes a broad ban on all cryptocurrency transactions involving Russia, aiming to disrupt the entire crypto infrastructure supporting Russian entities. Past data shows a 30% decline in centralized exchange flows to Russia but a 200% rise in decentralized and no-KYC channels, indicating displacement rather than elimination. The effectiveness of the ban hinges on controlling key chokepoints: stablecoin issuers, third-country intermediaries, and strict enforcement by EU licensed crypto service providers.
