U.K. Court Allows Case Forward in $172 Million Bitcoin Theft

A U.K. High Court judge has permitted a lawsuit to proceed concerning the alleged theft of 2,323 Bitcoin, currently valued at approximately $172 million, from a U.K. Resident. The case centers around claims that the victim’s estranged wife illicitly obtained his hardware wallet recovery phrase through the use of CCTV cameras and subsequently transferred the cryptocurrency without his consent in August 2023.

The Alleged Theft and Initial Claims

Ping Fai Yuen, the claimant, alleges that his wife, Fun Yung Li, secretly recorded him to acquire the seed phrase necessary to access his Bitcoin holdings. The stolen Bitcoin was stored in a Trezor cold wallet, secured by a PIN. At the time of the alleged theft approximately 30 months ago, the Bitcoin was worth just under $60 million . The funds were dispersed across 71 different Bitcoin addresses, with no transactions occurring since December 21, 2023 .

Evidence and Court Proceedings

Yuen reportedly installed audio surveillance equipment after receiving a warning from his daughter that his wife was attempting to access his Bitcoin. Recordings allegedly captured discussions related to the stolen cryptocurrency, including phrases like “The Bitcoin has transferred to me” and “take all of it” . The court filing also suggests the wife discussed potential methods for cashing out the Bitcoin in Hong Kong.

Following the discovery of the alleged theft, Yuen confronted his wife, resulting in his arrest and a guilty plea to charges of “assault occasioning actual bodily harm and two offenses of common assault” . Police subsequently arrested Fun Yung Li, seizing 10 crypto cold wallets, but released her after she provided a “no comment” interview.

Legal Challenges and Property Law

While the initial claim of “conversion” – a legal term relating to the wrongful exercise of ownership rights – was rejected by the judge as traditionally applying only to physical property, the case will proceed under alternative legal arguments. This highlights the ongoing adaptation of English property law to digital assets . The court is exploring whether claims of deceit or unjust enrichment could enable the recovery of the stolen Bitcoin .

Implications for Crypto Security

This case underscores the critical importance of securing the recovery phrase associated with hardware wallets. While these wallets offer protection against online hacking, they are vulnerable if the seed phrase is compromised. The incident echoes a recent case in South Korea where funds were stolen from a seized crypto wallet after law enforcement inadvertently published a photo of its seed phrase . The case also highlights the risk of “$5 wrench attacks,” where physical security vulnerabilities are exploited to gain access to crypto assets.

The outcome of this case will likely have significant implications for how U.K. Courts address future disputes involving the theft of cryptocurrency and the legal definition of ownership in the digital asset space .
