Many people believe that cold wallets and hardware isolation can keep them safe, but there is a harsh reality that must be acknowledged — even if you spend millions on top-tier security equipment, facing real threats can cause human fear to instantly break down all defenses. There's a saying in the security community: "A five-dollar wrench is enough to crack any encryption scheme," which sounds exaggerated but reflects a cold fact.

This issue once seemed distant from ordinary people. The situation in 2025 has completely changed. On-chain data is traceable, social media showcases everything, and middle-class investors, content creators, and even regular traders can become targets. A recent incident where a co-founder of Ledger was kidnapped in France serves as a direct warning — no one can guarantee their privacy is secure in the internet age.

So how should one defend? Traditional approaches are outdated. Security experts point out that true defenses must extend from the screen into the real world. Using multi-signature locks for large funds in different locations, setting up coercion-resistant PIN codes as backups, and maintaining an extremely low-profile lifestyle daily — these are the core principles. Someone proposed a practical plan called "Two-Step Exit": only keep daily spending limits in your everyday wallet, freeze major funds with multi-party signatures, and physically disperse private keys across different cities. It sounds complicated, but this complexity itself is the best protection.

The widespread adoption of KYC has become a double-edged sword. On one hand, compliance is clearer; on the other hand, your asset size and personal information are more easily linked precisely. Therefore, regardless of your asset scale, the habit you should develop now is: never show off your gains publicly, and never let strangers know your holdings' depth. The premise of security is always to make it impossible for others to see how much you have.
