On-chain laundering surges to $82B as Chinese-language networks entrench a resilient underground market

A new analysis from a leading blockchain-forensics firm maps a rapid escalation in crypto-enabled money laundering between 2020 and 2025, with estimated on-chain flows rising from roughly $10 billion to about $82 billion. This growth reflects both the larger pools of crypto liquidity and the maturation of service providers who stitch together bank access, exchange pathways and peer-to-peer trading across messaging apps. Chinese-language networks have emerged as a major node in that expansion, responsible for an outsized fraction of identified laundering activity and handling billions in 2025 alone. Investigators traced the activity to thousands of wallets and a handful of service archetypes, including brokers that arrange on-ramps, extensive mule infrastructures and informal over-the-counter trading venues that accept discounted tainted assets. Operators rely on reputation and escrow mechanisms inside encrypted chat platforms to match buyers and sellers and to keep funds moving even when specific channels are disrupted. That operational design increases resilience: disruptions to single channels typically trigger rapid migration rather than permanent shutdown. The concentration of services within language-specific communities also lowers coordination costs for criminals and complicates multinational enforcement, which often struggles with linguistic and jurisdictional friction. The report links these on-chain flows to a wider ecosystem of fraud, ransomware, and other off-chain criminal enterprises that use crypto as a routing layer. For policy and compliance teams, the findings underscore a shifting risk profile: laundering is moving away from regulated onramps toward decentralised or peer-mediated pathways that are harder to freeze or trace. Technological detection alone will not suffice; the structure of these networks requires combined actions across financial intelligence units, exchanges, messaging platforms and foreign partners. If left unchecked, the professionalization and geographic dispersion of these services will raise the cost and complexity of AML efforts while sustaining criminal revenue streams. The analysis concludes that tackling this problem will demand faster information-sharing, targeted sanctions, and strategic interventions designed to disrupt service intermediaries rather than only individual transactions.
