In a sweeping, months-long international investigation, the International Consortium of Investigative Journalists (ICIJ) has unveiled a vast and intricate criminal financial ecosystem built atop the world’s cryptocurrency markets. The project — titled “Coin Laundry” — exposes how human traffickers, narcotics syndicates, sanctioned states, ransomware groups, and global crime gangs are using major centralized crypto exchanges and cash-for-crypto storefronts to wash billions of dollars in illicit funds.
Drawing on leaked documents, blockchain data, confidential law enforcement memos, interviews with industry insiders, and on-the-ground reporting from more than 100 journalists across over 35 countries, the ICIJ paints a disturbing portrait of a parallel financial system: fast-moving, lightly regulated, and uniquely suited to help criminals vanish money into the digital ether.
A Global Criminal Network Hidden in Plain Sight
According to the ICIJ, crypto’s promise of borderless and near-instant transactions — often paired with a degree of pseudonymity — has opened the door to a modern underground banking system that functions far beyond the reach of traditional regulators.
Investigators found that illicit funds flowed through some of the world’s largest exchanges, including:
- Binance
- Coinbase
- Kraken
- OKX
- KuCoin
- Bybit
Although these exchanges maintain public compliance programs and collaborate with blockchain-analytics firms, ICIJ reporting suggests that criminals have repeatedly exploited loopholes, weak controls, and the sheer speed of digital transactions to move large volumes of dirty money unnoticed.
The investigation documents transactions tied to:
- North Korean hacking collectives, including groups known for multimillion-dollar cyberheists
- Russian and Chinese human-trafficking organizations
- Online fentanyl suppliers operating from China and Southeast Asia
- Mexican drug cartels, including networks linked to the Sinaloa cartel
- Russian organized crime syndicates with long histories of cross-border money laundering
One of the most brazen channels uncovered involved “crypto-to-cash” storefronts — small, sometimes unlicensed shops in places like Dubai, Ukraine, Serbia, and parts of Southeast Asia. These businesses allow customers to walk in with suitcases of cash and walk out with crypto, or vice versa, often requiring minimal identification. Journalists found that such storefronts frequently serviced couriers for cartels, sex-trafficking rings, and cybercriminal organizations.
Experts Say Crypto Is Now the New Offshore Haven
For decades, money launderers relied on opaque banking jurisdictions, shell companies, and offshore trusts to move and hide illicit funds. But the ICIJ argues that cryptocurrency has now supplanted many of these older systems.
“With crypto,” said one financial-crime analyst consulted by the ICIJ, “a cartel no longer needs to smuggle stacks of hundred-dollar bills in vehicle compartments or bribe bank employees. They can move millions with stablecoins, anonymizing wallets, and cross-chain bridges — and do it in minutes.”
Unlike traditional money laundering, which requires layers of shell companies and slow international transfers, crypto can operate at machine speed. Investigators found examples where criminal organizations cycled dirty funds through an exchange, bridged assets to a new blockchain, and sent the funds to overseas brokers within hours.
ICIJ Leadership Crypto Markets Becoming Shadow Banking System
ICIJ Executive Director Gerard Ryle, who previously oversaw investigations like the Panama Papers and Paradise Papers, warned that crypto now represents the next frontier of illicit global finance.
“For years we traced corruption, tax evasion, and secret wealth through offshore havens,” Ryle said in a statement accompanying the release of the reports. “Now we’re uncovering how powerful criminal networks have adapted those same methods to the crypto universe — sometimes with even fewer obstacles.”
Ryle said the investigation raises fundamental questions about accountability in the digital-asset world:
- How aware are major exchanges of the criminal flows passing through their platforms?
- Are compliance teams currently overwhelmed by the sheer scale and speed of blockchain transactions?
- Why do regulatory authorities remain so far behind, even after years of warnings?
“These findings show,” Ryle added, “that we are watching the emergence of a shadow financial system — faster, darker, and increasingly beyond the reach of law enforcement.”
Behind the Investigation A Worldwide Journalistic Collaboration
The expansive project involved a massive international media partnership. Outlets working alongside ICIJ included:
- The New York Times
- Le Monde
- The Toronto Star
- Malaysiakini
- The Indian Express
- Australian Financial Review
Journalists combined leaked documents, internal compliance reports, on-chain data analysis, and undercover fieldwork. Sources within crypto exchanges, blockchain-forensics companies, and financial-regulatory bodies spoke under conditions of anonymity to avoid professional retaliation.
Notably, the investigation relied not only on well-known analytics firms like Chainalysis but also on independent “blockchain sleuths” — small teams and solo researchers who track illicit activity across obscure chains, mixers, privacy coins, and darknet markets.
Response From Exchanges We Are Not Complicit
Some of the exchanges named in the ICIJ reports issued public statements following publication.
OKX
A spokesperson for OKX said the platform takes all allegations seriously and emphasized that the company invests heavily in compliance.
“OKX works closely with global law enforcement agencies and employs a multi-layered system combining AI-powered monitoring, veteran compliance teams, and on-chain analytics,” the spokesperson said. “We welcome scrutiny and will continue to enhance our protections.”
KuCoin
KuCoin said criminal exploitation of open financial systems is a risk for every financial institution — whether traditional banks or crypto platforms.
“This does not mean the institution itself is complicit,” a spokesperson said, adding that KuCoin maintains strict anti–money laundering and counter–terrorist financing protocols aligned with international standards.
“We use leading blockchain analytics partnerships, perform continuous transaction surveillance, and enforce stringent KYC and EDD requirements across all account tiers.”
Other exchanges contacted either declined comment or did not respond before publication.
Regulators Struggle to Catch Up
The reports underscore one of the most significant challenges facing global regulators: speed. Traditional anti-money-laundering systems were designed for a world of bank wires, SWIFT messages, and cross-border transfers that take days. Cryptocurrencies operate on blockchains that settle transactions in seconds.
Even when law enforcement agencies successfully identify an illicit wallet, criminals often move funds across chains, into mixers, or through multiple exchanges before officers can prepare warrants.
Investigators also found that many countries lack uniform rules for crypto monitoring, creating jurisdictional gaps that transnational criminal groups exploit.
A Financial System at a Crossroads
The ICIJ’s “Coin Laundry” project suggests that cryptocurrency has reached a critical moment. Advocates argue that digital assets bring financial freedom, innovation, and global accessibility. But the investigation reveals that without stronger oversight, the same technology is helping fuel some of the darkest criminal enterprises on the planet.
Whether regulators, exchanges, and industry leaders can reform the system — without stifling its innovation — remains an open question.
But one conclusion from the ICIJ is unequivocal:
Crypto has become one of the most powerful tools for modern criminal finance, and the world’s institutions are still racing to catch up.
