Security risks are frequently emerging in the crypto investment circle. Recently in France, there have been multiple malicious incidents targeting crypto practitioners—last Friday in Verneuil-sur-Seine, a senior executive of a crypto fund and their family were attacked, beaten, and tied up by three masked assailants at their residence. Fortunately, the victims escaped and sought help from neighbors in time, and the perpetrators fled the scene. Just the day before, a similar incident occurred in Saint-Léger-sous-Cholet, where a local crypto investor was kidnapped, beaten, and abandoned. These "smash-and-grab" attacks (violent robberies targeting individuals or small organizations) have been frequently reported in the European crypto community in recent years, reflecting that as industry wealth concentrates, personal safety has become a new risk point. For high-net-worth crypto industry practitioners, strengthening personal and family protection and reducing information exposure has become an essential task.
