Over the past six months in France, these violent, headline-grabbing kidnappings or attempted kidnappings, followed by demands for hefty ransoms, had one common thread: All targeted people with ties to the cryptocurrency world—in most cases, family members of crypto entrepreneurs or influencers.

While the growing popularity of cryptocurrencies has enticed criminals around the globe—including in the United States—the spree of recent attacks in France has shocked many by their brazenness, brutality and copycat nature. In two instances, the kidnappers cut off a victim's finger to scare families and colleagues into paying millions of euros in ransom, the authorities said—and in one of those cases, they threatened to drill into the victim's knee, according to France's interior minister.

The kidnappings were ultimately thwarted by the police or bystanders. The Paris police said 24 people were taken into custody on Monday and Tuesday in connection with the attempted kidnapping of a cryptocurrency entrepreneur's daughter in Paris, which was captured in a disturbing video.
