Rug pulls. Ransomware. Money laundering. Darknet markets. Human trafficking. Sanctions evasion. Terrorism financing.
Cryptocurrencies now sit at the centre of the world's most serious financial crimes. Yet most investigators, compliance officers, and legal professionals lack the training, tools, and frameworks to effectively detect, trace, and prosecute it.
Cryptocurrency crime is no longer a niche problem. Global crypto scam losses reached a record $17 billion in 2025, powered by AI-generated personas, cross-chain obfuscation, and increasingly sophisticated laundering routes.
Cryptocurrencies now sit at the centre of money laundering, terrorism financing, darknet market activity, drug and weapons trafficking, human trafficking, migrant smuggling, organised cybercrime, illegal gambling, counterfeit goods, wildlife smuggling, sanctions evasion, tax evasion, and unlicensed money transmission.
Rug pulls. Ransomware. Ponzi schemes. DeFi exploits. Exchange hacks. Wash trading. The attack surface is expanding faster than most organisations can track.
A RAND study conducted with the US National Institute of Justice and the Police Executive Research Forum identified 24 critical capability gaps in how law enforcement handles cryptocurrency-related crime.
Top priorities included standardised procedures for seizing and securing crypto assets, two-person verification controls, expanded practitioner training, and stronger inter-agency information sharing.
The study found that most small and mid-sized agencies lack access to effective blockchain tracing tools — and that even open-source solutions require technical expertise and infrastructure beyond the reach of many departments.
Fragmented jurisdiction, limited training, and unclear evidence-handling protocols remain the defining weaknesses across the board.
Most blockchain analytics providers offer powerful software — but software alone does not make an investigator. Their training is designed to teach you how to use their tool, not how to investigate cryptocurrency crime.
Investigators trained only on a vendor's platform are dependent on that vendor's data, that vendor's interface, and that vendor's continued access. When the tool changes, the skill disappears.
Compliance certifications from other providers focus heavily on AML frameworks and regulatory checklists — but leave investigators without the technical depth to trace funds across chains, analyse smart contracts, or handle evidence at a crime scene.
