"Money is gone, gone in the blink of an eye." Lao Zhang called, his voice trembling. He once had a balance of 2 million USDT in his digital wallet, but it was emptied without any authorization. This isn't a contract liquidation, nor project team跑路, but a complete digital asset theft.

The police asked around and finally left with one sentence: "Most likely, it was an insider mishandling." But the real vulnerability had long been hidden—system not updated in five years, WiFi password used for a lifetime, a phone filled with unknown financial apps, and even mnemonic phrases recorded in notes.

Having been involved in the crypto space for years, I repeatedly tell people: "If you want to make money, first learn to protect your money. 'Locking the door' is a hundred times more important than knowing how to bottom fish." Yet most people's eyes are fixed on hundredfold returns, while their assets are placed behind fragile defenses like paper.

Today, let's not talk about market trends. Instead, focus on three key points for survival.

**First, the secret of mnemonic phrases**. Never store them on your phone, cloud drives, or any connected device. Don't screenshot or copy to clipboard. The safest method is to write them by hand, prepare two copies, and store them separately. This is the last line of defense for your assets and must be kept offline.

**Second, devices should be dedicated**. If your assets are substantial, keep a clean, dedicated device for managing your wallet—no installing random software, clicking on unfamiliar links, or connecting to shared WiFi. Old phones are full of vulnerabilities—don't let them become entry points.

**Third, network habits must be regularly patched**. Change your WiFi password periodically, update your router firmware promptly. Many people don't realize that hackers often exploit the home network as an entry point, which is easier than directly attacking the wallet.

In the crypto world, there are no favors. Sophisticated position techniques and deep market analysis can't compensate for a single careless mistake. Those who truly survive in this field rely not on luck, but on unwavering dedication to safeguarding their assets.

Remember a simple truth: only those who can protect their assets are truly earning.
