In an audacious and violent attack in Le Chesnay-Rocquencourt, west of Paris, three suspects posing as police officers forced their way into a private residence. Once inside, they threatened a woman at knifepoint, demanding that her partner transfer their holdings of Bitcoin into a cryptocurrency wallet specified by the attackers. Under duress, €900,000 worth of Bitcoin was transferred before the criminals bound the couple and fled the scene.
Details of the Attack and Ongoing Investigation
According to initial reports, the assailants deceived the residents by claiming to be police, gaining entry through this ruse. Once inside, they made clear threats that compelled the couple to comply with their demand to transfer the Bitcoin. The transaction was completed on the blockchain, after which the perpetrators tied up the victims and escaped. The woman later managed to free herself and her partner, seeking help from a neighbor in the early morning. As of March 10, when the incident occurred, the suspects remain at large.
The Versailles Prosecutor’s Office has categorized the incident as kidnapping, armed robbery, and participation in organized criminal activity. The investigation is being handled by France’s Banditry Repression Brigade, a specialized national law enforcement unit dedicated to combating sophisticated violent crime. This taskforce focuses intensively on high-profile and complex criminal cases across the country.
Rising Threats Against Crypto Holders in France
This recent home invasion is far from an isolated event. In 2025 alone, France recorded 19 separate cases in which cryptocurrency owners were targeted in violent robberies—a figure that stands as the highest in Europe. The victims of these crimes hail from a variety of backgrounds, not just among the wealthy or well-known. Previous high-profile cases have drawn international attention, including the kidnapping of Ledger co-founder David Balland and the abduction of a crypto investor’s father for ransom. Notably, in Balland’s ordeal, the assailant went so far as to send one of the victim’s fingers as evidence, underscoring the brutality of such crimes.
A recurring theme in these attacks is the perpetrators’ advance knowledge of their victims. Digital footprints—including social media activity, leaked user data, and exposed personal information—often serve as the starting point for identifying targets. This environment allows attackers to pinpoint individuals with sizable crypto holdings with alarming ease.
Physical Security Risks Posed by Cryptocurrencies
Unlike traditional banking, where intermediaries and real-time security systems can interrupt or halt illicit transactions, cryptocurrency assets are directly controlled by their holders. If someone is coerced into making a transfer, banks might intervene through fraud detection or require transaction approvals; no such mechanisms exist for Bitcoin or similar digital assets. Once a blockchain transaction is initiated and confirmed, it cannot be reversed through legal or technical means—recovering lost funds is nearly impossible.
This leaves cryptocurrency owners uniquely vulnerable to physical threats. In practice, a criminal needs only a brief period of control to force a transfer that, within minutes, is permanently recorded on the blockchain. The irreversible and rapid settlement of Bitcoin transactions lowers the complexity threshold for such attacks, making them an enticing target for organized criminals.
Prominent industry security experts point out two protective measures. The first is the use of multisignature (multisig) wallets, which require multiple private keys to authorize a transaction, thereby preventing a single individual from transferring funds under duress. The second is maintaining strict privacy regarding crypto ownership and wealth, avoiding disclosure of sensitive information in public or online. While these strategies complicate attackers’ plans, they cannot fully eliminate the underlying risks.
France’s 19 reported attacks in 2025 illustrate a troubling trend: organized criminal groups increasingly regard cryptocurrencies as exposed stores of value and are refining their tactics accordingly.
