#加密钱包安全 Seeing this case verdict, I feel a bit heavy-hearted. A law enforcement officer stole tens of thousands of dollars worth of Bitcoin through violent means and was ultimately sentenced to 7 years in prison. This story reminds us of a very real issue—your crypto assets are often in your own hands.

The key point of this case is worth our deep reflection: the victim's private key or seed phrase may have been leaked due to illegal access to their phone. This means that no matter how much on-chain security technology is in place, it cannot prevent the breach at the source. That’s why I have been emphasizing position management and multi-layer security protection over the years—it's not just worrywart talk.

I want to share a few practical approaches: First, never put all your assets in one wallet or storage method; diversifying risk is the first line of defense. Second, hardware wallets are definitely worth investing in, especially when holding larger amounts. Third, backups of seed phrases and private keys should be stored in multiple physical locations, but only if those backups are secure—avoid taking photos or screenshots to store on your phone or sharing them. Fourth, be conscious of the amount of assets in your hot wallet for daily interactions; large assets should be stored cold.

In the long run, security awareness is more valuable than any tool. Protecting your assets is the best respect you can give to long-term investing.
