Analyst links $1.8 billion in dormant Bitcoin wallets to historic fraud

On-chain analyst Specter says he identified a cluster of Bitcoin wallets holding roughly 28,555 BTC, worth about $1.8 billion, that may be connected to one of the largest money-laundering cases in UK history. The investigation began weeks before Aug. 4, when a Bitcoin wallet dormant since 2017 moved 1,020 BTC, valued at approximately $60 million, and dispersed the funds across multiple addresses. Specter said that pattern is often associated with laundering. Following those transfers, he linked the wallet clusters to addresses publicly associated with the UK investigation into Qian Zhimin, also known as Yadi Zhang. The flagged wallets had been largely dormant since June 2021. Qian orchestrated an investment fraud in China between 2014 and 2017 that defrauded more than 128,000 victims. Some lost life savings and pensions. Total losses were roughly £600 million, or approximately $800 million. She converted a large share of the proceeds into Bitcoin, fled to the UK on a forged passport and attempted to launder the funds through luxury London property purchases before anti-money-laundering checks intervened. The case produced the largest Bitcoin seizure in the UK, with the Metropolitan Police taking control of more than 60,000 BTC. When authorities moved the seized Bitcoin in July 2021, those transactions created identifiable links between known addresses and the investigation. Qian pleaded guilty to money-laundering offences at Southwark Crown Court and was sentenced to 11 years and eight months in November 2025. For investors, the discovery highlights blockchain’s traceability but also the risks associated with dormant holdings, uncertain custody and potential law-enforcement action. Specter cautioned that on-chain evidence alone cannot establish whether the wallets remain under the same actors’ control, have moved to another custodian or have already been identified by authorities. Bitcoin traded at $64,252.37 at the time of writing.
