Investigation uncovers US$10 billion Bitcoin flows through hidden exchange wallet

US$10 billion worth of bitcoin moved through a hidden wallet over 2022–25, exposing exchange AML-risk issues.
An ongoing investigation by the International Consortium of Investigative Journalists (ICIJ) and blockchain-analytics firm Arkham Intelligence has identified a single wallet that processed nearly US$10 billion in bitcoin transfers between February 2022 and July 2025. The transfers, routed via one exchange embedded inside another entity, raise major regulatory and AML-risk concerns for the digital-asset ecosystem.
While the activity spans multiple years, the disclosures emerged publicly just recently and may trigger increased scrutiny of exchange operations.
