France has become the most dangerous country for cryptocurrency holders, accounting for approximately 70% of all ‘wrench attacks’ worldwide in 2026. According to Bitcoin journalist Joe Nakamoto, 41 crypto-related kidnappings have been recorded in just the first four months of the year — an average of one violent incident every 2.5 days. French national prosecutor for organized crime Vanessa Perrée confirmed that 88 individuals have already been charged in connection with these cases, signaling a sharp escalation in organized physical violence targeting digital asset owners.
The surge in attacks is directly linked to centralized Know-Your-Customer (KYC) data breaches, Nakamoto argues. A massive leak from hardware wallet provider Ledger in 2020 exposed the names, email addresses, and home addresses of over 270,000 customers worldwide. More recently, a breach at French crypto tax platform Waltio compromised another 50,000 users. In a further escalation, a French tax official has been formally accused of extracting and selling state-held data on crypto holders to criminal networks. Jameson Lopp, CEO of crypto wallet company Casa, described France as “the canary in the coal mine,” warning that KYC regulations are creating a surveillance apparatus that directly endangers bitcoin owners.
French intelligence reports that the attacks are orchestrated by foreign criminal syndicates, often based outside Morocco, which recruit local youths within France to carry out home invasions and kidnappings. In one high-profile incident, the wife of The Sandbox co-founder Sebastien Borget narrowly avoided a kidnapping attempt at the couple’s home near Paris, thwarted by neighbors. The concentration of major crypto companies — including Ledger and Binance France — as well as wealthy early adopters and executives, makes the country a prime target for attackers armed with leaked identity data.
The crisis has intensified opposition to centralized KYC data storage within the Bitcoin community. Security experts stress that even the strongest cryptography cannot protect against physical coercion at one’s front door. Nakamoto advises holders to maintain a low public profile, avoid revealing wallet ownership online, and use custody tools that allow freezing funds with a distress signal. A small decoy wallet may also provide an emergency buffer. As France’s experience demonstrates, regulatory data collection can become a direct physical liability when systems are breached, raising urgent questions about how to balance compliance with personal safety.
