Dismantling the Myth of Cryptocurrency as a Safe Haven for Illicit Wealth: Virtual Assets, Conflict Minerals, Terrorism Financing, and Grand Corruption, with Nigeria as a Global Case Study

Conventional wisdom among investigators, prosecutors, and the wider public holds that once illicit proceeds are converted into cryptocurrency, they effectively vanish beyond the reach of the state. This article challenges that assumption. Public blockchains are permanent, transparent ledgers; what criminals conceal is identity, not the movement of funds — a distinction properly understood as pseudonymity rather than anonymity, and one that trained investigators can routinely defeat through blockchain forensics, legal process, and international cooperation. Drawing on Nigeria as an in-depth case study, the article demonstrates that virtual-asset-enabled crime rarely operates in isolation. It is frequently embedded in a wider, converging criminal ecosystem that also encompasses illicit artisanal mineral extraction, armed banditry, terrorism financing, and grand corruption by politically exposed persons (PEPs) and senior public officers. Comparable convergences of conflict minerals, informal value-transfer systems, and virtual assets are documented in other jurisdictions, including the Sahel, suggesting the Nigerian pattern is an instance of a broader global phenomenon rather than a uniquely national one. The article reviews the relevant technology, forensic methodology, and international and Nigerian legal frameworks, and closes with policy recommendations for building investigative capacity, closing regulatory gaps between mineral and financial oversight, strengthening the PEP due-diligence regime, and deepening cross-border cooperation.
