Ping Fai Yuen is suing his wife and sister-in-law over the bitcoin.

A wife allegedly stole £180 million in bitcoin from her husband by secretly filming inside their home and spying on his passwords.

According to the High Court, Fun Yung Li took the cryptocurrency from Ping Fai Yuen while the couple was discussing divorce.

Yuen, 44, claims that his wife installed a secret CCTV system that recorded where he hid his security passwords at their family home in an exclusive Brighton neighborhood, according to the Times.

The businessman is suing his wife and sister-in-law for the Bitcoin, which has an estimated value of between £160million and £180million. The case relates to 2,323 Bitcoin.

According to Mail Online, the cryptocurrency was held in a digital ledger with an access key stored on a digital ‘cold wallet’, which is not connected to the internet and is protected by a six-digit PIN code.

Yuen claims that he first learned his wife was attempting to steal his Bitcoin in July 2023 when his eldest daughter voiced her suspicions.

He installed audio recording equipment in the family home, and said he can prove beyond doubt that Li ‘obtained the seed phrase and exfiltrated the Bitcoin’.

His wife was allegedly recorded discussing CCTV cameras she had installed in the home.

One transcript contained the exchange: ‘The bitcoin has transferred to me but can it be seen that you have taken it?’

Yuen also allegedly recorded his wife discussing the risk of being referred to police over possible money laundering offences given the enormous sums in the digital wallet, the Times reported.

Yuen claims that Li transferred his cryptocurrency to 71 other blockchain accounts, possibly with the help of her sister, Lai Yung Li.

The businessman was arrested when he confronted his wife in August 2023, and eventually pleaded guilty to actual bodily harm and two offences of common assault.

Yuen in turn reported the alleged theft of the Bitcoin, and his wife was arrested that December, the Times reported.
