90 Crypto Kidnappings and Robberies in 7 Months: Why France Is the Most Dangerous Country for Bitcoin Holders

The cryptography protecting your $Bitcoin is nearly unbreakable. The front door of your house is not. France has just put a number on that uncomfortable truth: 90 cases of crypto-related kidnapping, abduction, extortion, threats and violent theft between January 1 and mid-August 2026, according to figures the French Interior Ministry provided to Cointelegraph. That is a new case roughly every two and a half days.

Police made 223 arrests and jailed 126 people over the period. And yet the attacks keep spreading, from Paris to Marseille, Strasbourg, Toulouse, Grenoble and Nantes.

Why Is France the World Capital of Crypto Wrench Attacks?

A "wrench attack" is crypto slang for the oldest hack in the book: skip the encryption and threaten the person holding the keys. France has topped the global leaderboard for years. Jameson Lopp's long-running directory of physical Bitcoin attacks counts 365 cases across 60 countries since 2014, with France in first place. Security firm Gart.io has tracked 73 French attacks so far in 2026, ahead of the United States at 66 and the United Kingdom at 27. Chainalysis counted 30 publicly known violent incidents in France through mid-year and conceded the real figure was almost certainly higher.

The Interior Ministry's 90 blows every one of those tallies out of the water. The ministry only began recording this category of crime on January 1, 2026, so there is no official year-on-year comparison. But Chainalysis data shows French attacks running well above their historical baseline since late 2024, and 2026 is on course to roughly quadruple the 19 known incidents of 2025.

How Did Leaked Tax Data Turn French Crypto Holders Into Targets?

Here is the part that should worry every crypto holder in Europe. Chainalysis head researcher Eric Jardine believes the surge is very likely linked to a significant data breach. In 2024, a tax official in the Paris region leaked personal, financial and crypto-holding information on French taxpayers. Attacks spiked from late November that year. In January 2026, French crypto tax platform Waltio disclosed a breach affecting around 50,000 users, handing criminals a second target list.

Such breaches reveal who owns crypto, how much, where they live and how to reach them. The attacker's hardest job, finding a victim worth the risk, is done before anyone picks up a wrench. Of the French victims with known residency, 93 percent were French nationals, not crypto-rich tourists. Critics such as Bull Bitcoin founder Francis Pouliot have gone further, arguing that the EU's DAC8 crypto reporting regime, which expands mandatory data collection on crypto users, has turned Know Your Customer into a kidnapping manual.

Why Are Criminals Kidnapping the Families of Crypto Investors?

The most chilling trend is who gets grabbed. Globally, relatives and acquaintances made up 25 to 30 percent of violent crypto incidents by early 2026. In France, that figure is over 40 percent.

In May, six men allegedly tried to abduct the wife of The Sandbox co-founder Sébastien Borget from the couple's home near Paris, with one attacker posing as a delivery driver to get the gate opened. In August, a couple in rural France endured three separate break-in attempts after buying a house previously owned by crypto millionaires whose leaked tax records still listed the address. In 2025, the father of a crypto entrepreneur was held for two days in Paris while kidnappers severed part of his finger and demanded $5.6 million. In Finistère this April, five members of one family were held at their home.

Jardine says the pattern shows criminals doing reconnaissance first: social media, blockchain analysis, leaked data, insider tips. French authorities now treat the cases as organized crime and route them through JUNALCO, the national organized-crime jurisdiction.

How Do You Protect Your Crypto From a Wrench Attack?

The standard playbook still matters. A hardware wallet, a metal seed backup stored away from home and a healthy suspicion of phishing links remain the baseline, and the CryptoTicker shop stocks vetted hardware wallets if yours is overdue an upgrade. But none of that stops someone who already knows your address.

The new rules are about information, not keys. Never discuss holdings publicly or on social media. Keep your name off exchange leaderboards and conference badges. Consider a multisig setup where no single person, including you, can move funds alone, and a time-locked "duress" wallet that can be handed over under threat. Check whether your tax software or exchange has had a breach, and if so, assume your address is already in criminal hands. As Cointelegraph put it, cryptography can protect a wallet, but it cannot stop a $5 wrench.
