In May 2025, an attempted kidnapping in Paris targeted the daughter and grandchild of a crypto entrepreneur. The suspects did not succeed. This was the third known kidnapping attempt in France this year involving individuals tied to cryptocurrency.
French police are now investigating the series of cases. All three incidents involved people connected to the crypto industry. One case reportedly included a person who had recently converted a large amount of digital assets into fiat currency.
These events mark a rise in crypto violence in France. As more individuals gain wealth through digital assets, their visibility may be increasing their exposure to targeted attacks. Law enforcement has not disclosed the names of the victims but confirmed ongoing investigations into possible organized groups.
