French Kidnappers Demanding 660 Bitcoin (BTC) Found 0.066 in the Ledger

A Decimal Error 10,000 Times Over

The scheme collapsed at 4:30 in the morning on Feb. 6 in Juilly, a town in France's Seine-et-Marne department. Four to five masked intruders forced their way into a family home, overpowered the three residents and put a call through to a suspected organizer who was running the job off-site; the organizer never appeared at the scene, and every instruction that morning traveled by phone. On his order, the father connected his Ledger hardware wallet to a computer. The screen showed a balance of 0.066 Bitcoin (BTC), worth about €4,000. The men had built the raid around 660 BTC, a hoard then valued near €40 million at the prevailing Bitcoin (BTC) price, and a sum that would mark any holder as a crypto whale. The distance between the two numbers is 10,000 times. A device of this kind keeps its keys offline; a Ledger recovery key matters when the owner restores funds elsewhere, not when a balance is read on screen. In the wallet's own accounting there was no ambiguity: the device controls specific addresses, and those addresses held a fraction of what the file promised. The person on the line registered the error on the spot. The men left with the family's phones, a computer tower and the mother's bag, a haul worth less than €10,000 in total, against an expected take measured in tens of millions of euros. All three members of the household were injured during the break-in. Police later worked from surveillance footage to the getaway car, which turned out to be stolen.

The Meaux criminal court, the local venue for the department east of Paris, moved the case from an unsolved break-in to a ruling on Oct. 16, handing down firm custodial sentences to two defendants: a 19-year-old received three years and a 25-year-old received 18 months. The ruling reached a wide audience on Oct. 28, when Le Parisien laid out the file in detail. Sources close to the case told the paper that the raiders' target data came from a leak at a cryptocurrency tax-reporting platform in the weeks before the attack. Platforms of that type hold the exact combination a physical attack needs: an identity tied to a declared holding. The household's filed figure carried a misplaced decimal, 660 Bitcoin (BTC) on paper against 0.0660 BTC in fact, a 10,000-fold gap that turned a modest balance into a €40 million lure. Both men were arrested on Oct. 13, eight months after the raid. The 25-year-old was already in custody at Lille-Annœullin prison for a repeat offense of driving without a license; the 19-year-old was picked up in Roubaix. The leak sits only a few weeks before the attack, so the target file was compiled, shared and acted on inside a narrow window. What the court resolved covers the two men in custody; the breach that produced the list, the remaining accomplices and the suspected organizer who issued the Feb. 6 phone orders all sit outside the verdict, with no arrest reported.

The Balance Was Public All Along

Nothing about this target was ever hidden. Bitcoin's public ledger, kept by its proof-of-work network, shows the balance of every address, and the leaked file pointed at one specific household. A single check would have displayed 0.066 before anyone booked a car; the operation instead ran on a miskeyed decimal and ended the moment the real number reached the screen. That is the plain extent of what ended on Feb. 6: an armed raid organized around a figure that no explorer would have confirmed. The Oct. 16 verdict covers the hands-on crew; the phone-line organizer and the tax-platform breach behind the list remain at large, and for readers tracking Bitcoin security incidents, the next development in this case will come from that side of the file.
