A recent surge in crypto-related kidnappings in Paris has highlighted a dangerous misconception among criminals: the belief that cryptocurrency transactions are untraceable. Chainalysis CEO Jonathan Levin addressed this issue at the 2025 Consensus conference, emphasizing that law enforcement agencies have become increasingly adept at tracking and recovering illicit crypto funds.
“For whatever reason, there is a perception that’s out there that crypto is an asset that is untraceable, and that really lends itself to criminals acting in a certain way,” Levin stated. He noted that this misunderstanding may be contributing to the recent spate of violent incidents targeting individuals in the crypto industry.
Two significant attacks occurred in Paris this month. On May 13, three assailants attempted to kidnap the daughter and grandson of Pierre Noizat, CEO of French crypto exchange Paymium. Earlier, on May 3, the father of another crypto entrepreneur was held hostage for several days in a €7 million ransom plot. These incidents have prompted French authorities to engage with crypto professionals to address escalating security concerns.
Levin emphasized that the traceability of cryptocurrencies has led to numerous arrests and successful recoveries of stolen funds. “The message needs to get out there that these payments are traceable and that these units within the law enforcement agencies have actually been very successful at holding some of those people to account in those kidnapping cases,” he said.
Despite these advancements, Levin acknowledged that the rise in physical attacks remains a “bleak” situation. He urged individuals in the crypto space to exercise caution regarding the personal information they share online, as oversharing can make them targets for criminals.
The incidents in Paris are part of a broader trend of in-person crypto-related crimes. According to data compiled by Casa co-founder Jameson Lopp, there have been 22 recorded incidents of such crimes in 2025, compared to 28 in 2024. However, experts believe the actual number may be higher, as many victims choose not to report these crimes due to fear of revictimization.
As the crypto industry continues to grow, the need for increased awareness and security measures becomes ever more critical. Educating both the public and potential criminals about the traceable nature of blockchain transactions may serve as a deterrent to future crimes.
