Till Death or Seed Phrase: Woman Accused of Spying on Husband, Stealing $172 Million in Bitcoin

A dispute over more than $172 million in Bitcoin has moved forward in the UK’s High Court of Justice, where a man alleges his estranged wife stole thousands of coins from his hardware wallet using covert surveillance inside their home.

Court filings show that Ping Fai Yuen, a UK resident, held 2,323 Bitcoin in a Trezor hardware wallet in 2023. 

On Aug. 2 of that year, the full balance was transferred without his knowledge. The funds were later split across 71 separate addresses through a series of transactions. No movement has been recorded since Dec. 21, 2023.

Yuen claims his wife, Fun Yung Li, obtained access to the wallet’s recovery phrase, which can be used to recreate the wallet and move funds. 

The filings allege she recorded him inside their home to capture the phrase, possibly with help from her sister, Lai Yung Li, who is also named as a defendant.

According to the claim, Yuen had been warned by his daughter in July 2023 that Li was attempting to access his Bitcoin. 

He then installed audio recording equipment in the residence. The recordings are cited as key evidence. In one excerpt referenced in court, Li is alleged to have said, “The Bitcoin has transferred to me” and “take all of it.”

The filings also describe a recording from July 29, 2023 in which Li allegedly discussed camera placement and the location where Yuen stored his wallet credentials. The claim states she was “covertly recording” him in an effort to obtain access.

After discovering the transfer, Yuen confronted Li and assaulted her. He was arrested and later pleaded guilty to assault occasioning actual bodily harm and two counts of common assault.

Police opened an investigation into the alleged theft and arrested Li in 2023. Officers seized 10 crypto cold wallets during a search, including several linked to Yuen. Authorities later released Li after a no comment interview. The police have since stated they will take no further action without new evidence.

In November 2025, Yuen sought a proprietary asset preservation injunction. He asked the court to confirm his ownership of the Bitcoin, freeze Li’s crypto holdings, and order the return of the assets or an equivalent sum in British pounds.

‘Damning’ evidence of bitcoin theft

In a judgment following a March 2 hearing, Justice Cotter said Yuen’s case shows a strong likelihood of success. He pointed to the warning from Yuen’s daughter, the audio transcripts, and the discovery of equipment capable of accessing the wallet.

“The evidence is that he was warned of what the First Defendant was seeking to do, the transcripts are damning,” Cotter wrote.

The judge also cited Occam’s razor, the principle that the simplest explanation with the fewest assumptions is often the most likely. He said that this straightforward account aligns with the available evidence, and noted that Li has had the opportunity to present her version of events but has not done so in the proceedings.

Cotter added that the volatility of Bitcoin supports the need for a swift trial, as the value of the disputed assets may shift during the course of litigation.

The case is expected to test how English courts handle ownership and recovery claims tied to digital assets.
