#数字资产市场动态 Your 3 million U was gone in a second.

This isn't a liquidation, nor exchange risk, but a real "digital thief burglary" happening in the crypto world.

A friend experienced it: watched helplessly as their wallet balance was wiped out, without ever pressing any authorization keys. Calling the police was useless; the response was just "maybe a family member mis操作."

Only after dissecting it did they realize that the vulnerabilities were all embedded in daily habits—three years without updating the system, seven years without changing the WiFi password, installing a bunch of sketchy finance apps on their phone, and even more astonishing, having mnemonic phrase screenshots stored in a memo.

You might think the wallet's security door is solid, but the key is hanging openly outside. $AXS

Having been involved in blockchain security incidents for a long time, I’ve summarized with those around me: "Enter the crypto world first learn defense, then talk about making money." Too many people have dreams of hundredfold returns, yet put millions behind paper-thin walls.

Instead of staring at the market every day, it’s better to first master three ironclad rules—each earned at the cost of real money.

**First, keep mnemonic phrases on paper only, completely isolated from the internet.**

Never use WeChat, memos, or phone screenshots—it's like hanging the key on a notice board. The truly secure method is to write it by hand, store it in two separate places, and never let it connect online.

**Second, allocate a dedicated isolated device for large assets.**

If your holdings are substantial, get a clean device solely for managing your wallet—no unnecessary apps, no clicking on unfamiliar links, avoid public WiFi, and especially don’t use old devices. Vulnerabilities are like sieves. $BTC

**Third, regularly update your defenses.**

Change your home WiFi password periodically, upgrade your router firmware promptly—many hackers slip in through these "side doors."

We are too used to discussing how to make quick money, but forget how to safeguard our funds. In this world, security is not optional; it’s a prerequisite for survival.

First, protect your principal, then talk about doubling it.
