As regulators clamp down on illicit transactions, crypto users and institutions are navigating a complex web of compliance and enforcement. This article explores the latest statistics and trends shaping OFAC sanctions and crypto transactions in 2025, helping readers understand the key developments that are reshaping this critical space.
