Today, another netizen's assets were stolen. At three in the morning, the crypto security group was awakened by a voice message: "The child's 3 million study abroad fund is just gone!" Old Lin's cries are heartbreaking, and the reason is that for convenience, the mnemonic phrase was screenshot and sent to the family group.
The first lesson in the crypto circle is not how to make money, but how not to lose money. As a crypto analyst with ten years of experience, I have seen too many tragedies of "overnight losses." Once assets are stolen, it is basically like spilled water; hackers will clear traces within 72 hours and split the assets across chains, making the chances of recovery almost zero.
01 Mnemonic Phrase: The lifeline of your assets, also the breakthrough point for hackers.
The case of Old Lin is not an isolated incident. Statistics show that nearly 70% of asset loss cases arise from improper storage of mnemonic phrases. What is a mnemonic phrase? It is not an ordinary password, but the "universal key" to your encrypted wallet, consisting of 12 or 24 English words.
Once mnemonic phrases touch electronic devices, it's like sending an invitation to hackers. Many people like to store mnemonic phrases in their phone memos, save screenshots, or even send them to WeChat groups, which is akin to running naked in front of hackers.
My approach is simple and straightforward: buy a corrosion-resistant metal plate, handwrite the mnemonic phrase, and then lock it in a safe. Don't use a printer, don't store it in the cloud, just write it down honestly. This is offline security, and that is true security.
A friend even divided the mnemonic phrase into three parts, storing them in a bank safe and with trusted relatives. Although it may seem cumbersome, this caution is not excessive for large assets.
02 Trading Environment: Clean enough to perform surgery.
Your trading device should be as clean as a surgical room. I specifically prepared an old phone, restored it to factory settings, and only installed the official wallet application. Any third-party market plugins and free coin acquisition tools are all firmly rejected—they often harbor malicious intent and can steal your clipboard.
Do not connect to public WiFi; I cannot stress this enough. Traffic hijacking is rampant, and hackers love to wait for prey on public networks.
Before each operation, I always follow the "three-step verification method": open a video to guide family members in real-time, check if the address length is correct, and confirm that the first two and last four digits match those of the recipient. Use the official APP to scan codes and never manually enter addresses.
03 Platform Selection: Don't let small profits blind your eyes.
The low fees of small exchanges are like hooks in bait. A friend of mine once invested 80,000 yuan due to a platform's 50% discount on fees, only to find the platform suddenly ran away, losing all his funds.
My principle is: only recognize the top three exchanges—Binance, OKX, and other well-established platforms with over 8 years of history. These platforms have international regulatory licenses and over a hundred million users, so they won't suddenly disappear.
Immediately bind the Google Authenticator after registration; do not rely solely on SMS verification. SMS interception is a common tactic used by hackers, while dynamic verification codes are much safer.
Newcomers should completely avoid leveraged trading. Leverage is a magnifying glass; it shines brightly when rising and leaves nothing when falling. I have seen too many newcomers lose their capital in days due to leverage; playing spot trading honestly is the right path.
Conclusion: Security is a marathon, not a sprint.
In the cryptocurrency world, preserving life comes first. If you can't pass the security check, no matter how much you earn, it's still working for hackers. Take 5 minutes to check: is your mnemonic phrase saved by hand? Are there suspicious plugins in your device? Have you explained the operational risks to your family?
As an experienced investor, I can responsibly say: the key to survival in the cryptocurrency world is not the myth of becoming rich overnight, but avoiding 90% of the pitfalls. Implement security measures properly, and let hackers cry and become unemployed!
