A hoarse voice came from the other end of the phone: "3 million U lost. Just like that, the balance was wiped out in a second. I didn't do any authorization operations at all."

This isn't a liquidation, nor platform risk, but the most heartbreaking thing in the crypto world—assets being stolen directly. After reporting to the police, their casual response was: "It might be a family member's mistaken operation." And that was the end of it.

Later, when checking the account, I realized the problem had long been hidden in daily habits: a three-year-old unupdated phone system, WiFi passwords used for seven or eight years, a phone filled with rogue apps, and screenshots of seed phrases still saved in memos.

In the blockchain world, the anti-theft door looks impregnable, but the key is hanging openly on the doorknob.

I have been paying close attention to the methods of crypto hackers, often telling those around me: "Enter the crypto space, first learn to defend, then think about making money." Too many people focus solely on achieving hundredfold returns, placing their assets behind a "paper-thin wall."

**Tip 1: Invisible Management of Seed Phrases**

Seed phrases have only one destiny—written by hand on paper, completely isolated from the internet. Saving in WeChat, memos, or screenshots on your phone is equivalent to sticking the key on the community bulletin board. Hackers don't need to crack anything; they just find your seed phrase, and the account is theirs.

The correct approach is simple: write it down with a pen, and store two copies in two secure places. Pen and paper are always the most reliable.

**Tip 2: Devices Must Be Independent**

If your assets are substantial, use a dedicated clean device to operate your wallet. The requirements for this device are: no installing random software, no clicking on unfamiliar links, no connecting to public WiFi. Many people manage their assets with old phones that are five or six years old, full of system vulnerabilities—it's like guarding your vault with a dilapidated house.

**Tip 3: Secure Your Network Ports**

Regularly change your home WiFi password and update your router firmware promptly. You might think hackers can only attack head-on, but often they sneak in through the side door of your home network. If your router is compromised, all your connected devices are exposed to risk.

In the crypto world, we always discuss how to earn faster or chase the trend. But in reality, protecting your assets is much harder than earning them. Security isn't a multiple-choice question you can give up on; it's a survival gate you must pass.

True stable profits never come from boldness, but from meticulous care.
