An outdated system that hasn't been updated in three years, a WiFi password unchanged for seven years, a pop-up "Financial Advisor" app that keeps bothering you, plus—remembered mnemonics stored in your phone notes.

It’s this kind of combination that caused an investor’s 3 million USDT to vanish in an instant. He told his friends, "It was right in front of me, the balance suddenly dropped to zero, but I didn’t authorize anything."

This isn’t an exchange跑路, nor a leverage liquidation. It’s a real case of "digital assets being stolen." The response after reporting to the police was quite heartbreaking—"It might have been a family member’s mistake." But in fact, this investor lives alone, with no family.

In the crypto world, your security measures may seem as solid as iron, but the keys are casually hanging on the doorknob.

Many people focus all their energy on researching how to bottom fish, chase highs, or find 100x coins, but they overlook a fundamental question—how to protect the money you’ve already earned. It’s like building a fortress: no matter how high and thick your walls are, if the gate is made of paper, all your efforts are in vain.

**About Mnemonics: Paper Storage Is the Only Solution**

Don’t store them in WeChat, cloud drives, or any screenshots. That’s like leaving your house key on the community bulletin board. There’s only one correct way: write them down on paper with a pen and store them separately in two secure places. No connected device should ever access them. Including that old phone you haven’t used in ages—its system vulnerabilities are like sieves.

**Isolated Devices for Wealth Separation**

If your crypto assets have exceeded your psychological threshold, prepare a dedicated clean device to manage your wallet. Don’t install unrelated apps, don’t click on unfamiliar links, and absolutely avoid connecting to public WiFi. Many hackers don’t need advanced techniques—they can breach through vulnerabilities in your home network.

**Cybersecurity Requires Regular Maintenance**

Regularly change your home WiFi password and update your router firmware promptly. It sounds basic, but most people have never done it. Hackers love to exploit these overlooked gaps to break in.

The crypto market has always taught us how to make money—analyze tracks, manage positions, grasp the rhythm. But no one often talks about how to protect your money. In reality, from beginner to seasoned investor, those who survive understand one thing: the trading strategies you painstakingly develop can be wiped out by a single lazy security setup.

The real first pot of gold isn’t about catching a coin’s rise, but about never losing assets due to security vulnerabilities from the start to now. It may not sound sexy, but that’s the secret to long-term survival.
