In 2023, crypto money laundering fell 29.5% YoY to $22.2B, 109 addresses got $10M+ in illicit crypto each, and five off-ramp services got 71.7% of illicit funds
Context & Ripple Effects
The decline follows a 2022 surge in laundering volume, when illicit addresses sent nearly $23.8B, and sits alongside Chainalysis’s separate finding that illicit-address receipts also fell in 2023.
Concentration is the durable part of the story: earlier research found that five services controlled 55% of laundering flows in 2020, while the 2023 data shows an even larger share routed through five off-ramps.
First-order effects
- Five off-ramp services become the immediate choke points for identifying and disrupting most illicit cash-out activity, since they handled 71.7% of the reported funds.
- The 109 addresses receiving more than $10M each are a far narrower set for investigators and compliance teams to prioritize than the full universe of illicit addresses.
Second-order effects
- Exchanges, wallet providers, and analytics vendors connected to these off-ramps face stronger incentives to improve transaction monitoring and counterparty screening around the concentrated routes.
- Criminal operators may have to diversify cash-out paths if scrutiny constrains the dominant services, potentially shifting activity toward less visible channels rather than eliminating it.
Third-order effects
- The pattern suggests crypto anti-money-laundering enforcement can increasingly be organized around a small number of conversion gateways, rather than attempting to police every on-chain transfer equally.
- If concentration persists, the sector’s legitimacy challenge will hinge less on blockchain traceability alone and more on whether off-ramps consistently apply controls as illicit flows move between crypto and traditional money.
The trend: Crypto compliance is moving toward choke-point enforcement, with a small set of off-ramps carrying outsized responsibility for stopping illicit funds from becoming spendable money.
