Having worked with on-chain data for so many years, I've heard too many similar stories. Lao Lin's voice filled with regret still catches people off guard—his wife accidentally operated, and 3 million in study abroad funds just disappeared. The reason? A screenshot of a mnemonic phrase circulated in the family group chat.

Such tragedies are common. In the crypto world, there are no customer service rollbacks, no bank freezes for protection. Your assets are not just numbers; they are real gold and silver.

**How to store mnemonic phrases safely?**

You might have heard this advice a hundred times, but most people still save screenshots of their mnemonic phrases on their phones. WeChat transfers, cloud notes, note-taking apps—easy to operate, but what’s the result? One organization’s statistics show that 70% of asset loss cases are due to electronic storage issues.

Actually, the solution is simple: spend a few dollars to buy a metal mnemonic plate, manually carve each word, and store it in a safe. It can withstand fires and floods. Much more reliable than paper.

**Is your operating environment secure?**

Many people think they are safe as long as they haven't clicked phishing links, but the real risk lies in devices and networks.

Public Wi-Fi is the biggest trap—hackers set up a "free Wi-Fi" at cafes, and they can intercept every data packet during your transfers. Also, those "airdrop tools" and "market trend plugins" installed on your phone often secretly read your clipboard in the background.

One way is to turn an old phone into a dedicated wallet device: factory reset it, install only the official apps, and avoid anything else. Simple and crude, but effective.

**The last line of defense: family members must also understand the rules**

Lao Lin's wife’s mistake was here—she had no idea what that "operation guide" meant. If family members access your account, they must pass a "three-step verification": personal confirmation, a cooling-off period, and multi-party review. Even close relatives must follow the procedure.

Crypto assets leave no room for regret, so every step must be carefully calculated.
