A cryptocurrency investor almost handed over 3 million assets to someone else under the meticulous planning of an acquaintance. This "crypto veteran" gained trust over half a year—staying up late to monitor the market, patiently explaining candlestick charts, and voluntarily sharing the burden during losses—until that night when they suddenly urged, "Quickly migrate your assets! The platform is about to delist, recite the seed phrase to me!"

A friend's remark instantly woke them up: "Isn't this just asking for your bank card password?"

The chilling truth behind it surfaced—no matter how secure the Bitcoin network is, it can't prevent human nature's traps.

**Code can't prevent human greed**

Statistics show that the leading cause of lost crypto assets isn't hacking or exchange bankruptcies, but scams by acquaintances and social engineering attacks. Blockchain private keys and seed phrases are designed to be extremely secure, but once they leave physical carriers, they become the most vulnerable link.

Some save their 12-word seed phrase as a screenshot in WeChat favorites; losing their phone means assets vanish entirely. Others are moved by "investment" stories, transferring funds privately, only to see the other party vanish into thin air. Still, some receive urgent notifications from "a major exchange," and follow instructions to transfer assets to a "new address"—only to find they've entered a carefully crafted fake app.

**The three most common scams in the crypto world**

The first type is impersonating blockchain projects and exchanges. These scams often start within communities, using fake official accounts to post "urgent notices" or "limited-time benefits," tricking users into entering private keys or seed phrases on fake platforms.

The second type involves promises of high-yield investments. Numbers like "20% monthly returns" have long been banned by regulators in traditional finance, but they still have a market in crypto. Victims often see stories of financial freedom shared within their social circles, only to realize it was a carefully scripted scheme to harvest users.

The third type is private investment on behalf of others. Trusted acquaintances recommend a "primary market project" and ask for remittances to private accounts. When tokens fail to be delivered or go to zero, the other party has already deleted contacts and disappeared.

Remember one thing: code won't lie, but people will. The last line of defense for protecting your assets is always your own judgment.
