74-Year-Old California Man Missing; Kidnapping Suspected Over Family Crypto Fortune

Authorities in San Bernardino County are investigating the disappearance of 74-year-old Naiping Hou, who went missing in early May under suspicious circumstances believed to be linked to his family’s crypto wealth.

Hou left his home without his phone on a Monday and never returned. Days later, his silver Toyota Yaris was discovered abandoned near a hiking trail in Rancho Cucamonga.

On May 4, he was officially declared missing.

Police Probe Fraud in Missing Crypto Investor Case

By July 7, the San Bernardino County Sheriff’s Department confirmed its Specialized Investigations Division was treating the case as suspicious, citing evidence of “extensive fraudulent activity” involving Hou’s bank accounts.

Investigators revealed that an unknown individual used Hou’s phone and impersonated him to communicate with his family, raising concerns that Hou may have been kidnapped.

No suspects have been named, but authorities have not ruled out foul play.

Hou’s son, Wen Hou, has offered a $250,000 reward for information that could lead to his father’s safe return.

Wen, who has worked as Chief Investment Officer of hedge fund Coincident Capital since 2019, built his fortune in crypto and believes the motive behind his father’s disappearance may be financial.

“He had no reason to disappear,” Wen said in an interview with KABC. “I miss him a lot. He’s sort of a guide to my life.”

Experts suggest the case fits a growing trend of physical attacks targeting individuals linked to digital wealth.

Local and federal agencies now use blockchain forensics to follow the money in these cases.

Crypto-Linked Violence Hits Record Levels in 2025

Violent physical attacks targeting cryptocurrency holders, known as “wrench attacks,” are sharply rising in 2025, with 35 cases already reported by July, according to Chainalysis.

The Asia-Pacific region has seen some of the worst violence, with countries like Japan, Indonesia, and the Philippines reporting a surge in kidnappings and extortion linked to crypto ownership.

Driven by Bitcoin’s recent surge past $122,000, criminals are increasingly shifting from online hacks to real-world violence.

So far this year, over $2.17 billion in crypto has been stolen globally, surpassing 2024’s total. Attacks on personal wallets now account for nearly 25% of stolen funds.

Chainalysis found that retail wallet holders are now the main targets. Users in the U.S., Germany, and Japan report the most cases, while India, Chile, and the UAE see the highest average losses.

Improved security at exchanges has pushed attackers toward less protected individuals with high-value wallets.

The trend is also being fueled by advanced tactics. Chainalysis and CertiK report growing use of AI tools to identify and manipulate victims, often through phishing and impersonation schemes.

CertiK estimates crypto users lost $2.2 billion in the first half of 2025 alone, with wallet breaches making up $1.7 billion.

“The rise of wrench attacks is a stark reminder that digital assets are only as safe as the people who hold them,” Chainalysis said.
