The sharp rise in physical attacks targeting crypto holders is no longer a problem confined to high-profile industry figures — it is reaching ordinary holders and their families, as recent cases in France involving kidnapped children and elderly relatives have demonstrated. French prosecutor Vanessa Perrée has issued a direct public warning to crypto holders and their relatives to exercise greater vigilance and specifically to avoid overexposure on social networks that could make them identifiable targets. The advice is straightforward but frequently ignored: publicly sharing crypto gains, wallet balances, NFT purchases, or any signals of significant digital wealth on social media creates a trail that criminal networks are actively monitoring and exploiting.

Beyond social media discipline, there are several practical steps that significantly reduce physical risk. Using a hardware wallet stored securely and separately from your home address removes the most common point of leverage attackers use. Diversifying holdings across multiple wallets means that even a forced disclosure cannot result in a complete loss. Using multi-signature wallet setups that require approval from multiple devices or locations makes instant forced transfers technically impossible, buying time for intervention. Keeping knowledge of your holdings limited to as few people as possible — including avoiding discussion in social or professional circles — reduces the probability of being identified as a target through information leakage. The underlying message from both French law enforcement and blockchain security researchers is consistent: in a world where crypto transactions are irreversible and pseudonymous, the security of your holdings increasingly depends on how visible you make yourself as a target, and the most effective protection is making sure you never appear on the list in the first place.
