#数字资产市场动态 just clicked… After my wife operated, three million U was gone. My husband didn’t say a word all night.

"Bro, my wallet is emptied. Three million U. My wife just clicked confirm."

At 3 a.m., A Zhuang’s voice was tinged with tears. I didn’t comfort him first, but asked directly: "Where’s the screenshot of the mnemonic? Is it still saved in WeChat?"

There was silence on the other side. That silence was colder than any margin call news.

**Seemingly absurd, but actually happening**

That day, during a business trip, he took a screenshot of the twelve mnemonic words for convenience and posted it in the family group. He even recorded a tutorial video on "Copy → Next Step."

His wife followed the tutorial, and after thirty seconds, all assets on the chain were transferred out in one go, leaving the account empty.

When reporting to the police, the record read: "Family member operated voluntarily, no criminal intent." In other words: can’t recover it.

**The problem isn’t "clumsy hands"**

Don’t rush to blame the family. The real black hole is something he dug himself:

· Old Android phone hasn’t been updated in three years, Wi-Fi password is so weak it’s obviously the neighborhood name
· A bunch of malicious plugins in the browser claiming "free airdrops"
· WeChat automatically uploads original images to iCloud…

Hackers don’t need much effort; a simple combo can directly steal assets. The server automatically clears logs, leaving no trace.

**Three iron rules learned from the three million U**

Rule 1: The mnemonic is your life. Manually engraved on metal plates, stored in multiple fireproof safes. Never screenshot, never sync to the cloud.

Rule 2: The device used for operations is the vault. Use a dedicated offline phone with only the official wallet app installed. Disconnect from the internet before each operation, and clear the clipboard after.

Rule 3: Family members must supervise transfers on the same screen. If someone else must transfer on your behalf, do a video call, verify the last four digits of the recipient address one by one, pause for three seconds before confirming—to prevent assets worth millions from evaporating in a second.

Now, A Zhuang spends every night polishing his titanium steel plate. He says it’s the "hypnotic sound" bought with three million U.

Don’t wait until an asset crisis to start protecting—market conditions can wait, you can turn back, but on-chain transfers have no undo button. Preserving principal is a lesson more valuable than predicting rises and falls.
