#私钥与钱包安全漏洞 Trust Wallet attack incident is worth paying attention to, but the core issue reflected here is deeper than just asset theft — it involves control over developer devices or code repositories, which means future versions of the wallet could potentially have backdoors.

From a copy-trading perspective, the lessons from such black swan events are very practical: First, do not concentrate all funds in a single wallet solution; instead, diversify across multiple wallets based on the amount of funds and risk appetite, just like splitting positions in copy trading; second, a combination of cold wallets + hardware wallets, although more complex to operate, is indeed more secure for managing large sums. My own practice is to keep active trading funds in hot wallets, and transfer positions held for over three months to cold storage.

The most practical advice is to immediately check device security, especially if you have recently interacted with Trust Wallet. Additionally, operations like exporting private keys, backups, and transfers must be done in a completely offline environment — this is not excessive caution, but a necessary safeguard.

Security vulnerabilities are always more deadly than market fluctuations, because the former can wipe out your account in one go without a chance for stop-loss.
