#加密资产安全与托管 Two malicious cases related to crypto assets have been exposed in a short period, highlighting issues that deserve attention.

In the first case, the victim disclosed information about their father's crypto holdings to a stranger, ultimately being coerced into revealing their private key under torture, leading to asset theft; in the second case, the suspect was caught carrying a note with their seed phrase. These two details point to the same critical vulnerability—**the extreme fragility of private key management**.

On-chain data shows that holders of large amounts of crypto assets often become high-risk targets. The key issues are:

1. **Information Leakage Chain**: Exposure of asset scale → targeting as a target → physical coercion to obtain information. Victims may not even need to actively reveal their identity; a simple statement like "family has crypto assets" can trigger subsequent risks.

2. **Private Key Carrier Risks**: Physical records, digital notes, email backups—any form of private key record, physical or digital, is a potential attack surface. Once obtained, assets can be lost instantly.

3. **Necessity of Custody Options**: While self-custody of private keys embodies the spirit of decentralization, for large asset holders, professional custody services, multi-signature wallets, cold storage, and other solutions can significantly reduce passive risks.

For users holding large amounts of crypto assets, asset security is not only a technical issue but also a matter of life safety. How to balance convenience and security is a question worth serious consideration.
