According to online reports, a16z Crypto published an article on the personal security of encrypted assets, emphasizing that physical security is also crucial in the protection of digital assets. The article pointed out that while many users focus on digital security measures, such as using hardware wallets and multi-signatures, ignoring physical security can lead to serious consequences. For example, attackers may obtain sensitive information through social engineering, or directly threaten individuals to obtain private keys. Therefore, a16z recommends that users take comprehensive security measures, including but not limited to: avoiding discussing the amount of crypto assets held in public. Store private keys and mnemonics in a secure, decentralized location. Regularly update security policies to protect against potential physical and digital threats. A16z emphasizes that as the value of encrypted assets increases, users must pay attention to both physical and digital security to fully protect their assets.
