I recently came across a painfully stark comparison: depositing 500,000 USD into a bank takes 5 minutes, but clicking on a stolen U-link is gone in less than 1 second. This isn’t a joke—it’s a true snapshot of today’s scams.

Scammers in the country have upgraded from traditional telecom fraud to cryptocurrency scams, and their methods are becoming more and more sophisticated. I recently looked into this industry chain and found the core reason they can get away with it: cryptocurrencies are not legally protected in China. When many victims report to the police, the police don’t even know what USDT is. They tell you directly that it’s not legally protected—let alone file a case for investigation. In the end, victims often can only chalk it up to bad luck.

Today, I’ll break down the three most common types of U-stealing scams that lure the largest number of people. The first is QR code contract authorization theft. When scammers “trade” with you, they’ll send you a QR code to scan—but this is absolutely not a transfer. It’s a smart contract that can control your wallet. The key point is: any scam where, after scanning, you still have to transfer to a third party in order to complete the transaction is a scam. I analyzed these QR codes, and what came out were third-party redirect links. A normal QR code should directly resolve to a transfer address. This scam is especially good at tricking newcomers, because they’ve been brainwashed by promises of high returns. With just a couple of lines, scammers can bamboozle them into going along with it. After getting scammed, the victims even end up thanking the scammer foolishly.

The second is a clipboard version virus. I think this is the most vicious one. A fan told me that once his computer copies a Bitcoin address, it gets replaced, while other text is unaffected. Scammers typically send you some trojan virus files with especially enticing names. Once you download and open these files, any transfer links you copy afterward will turn into the scammer’s address. For example, you might copy an address ending in 123, but when you paste it, it becomes 567. So never click on random download links—this is how you can avoid this kind of U-stealing risk.

The third is fake wallet U-stealing, which is also a high-frequency hotspot for scams. Since cold wallets are open source, it’s not hard for scammers to imitate one. This type of scam usually traps people in a chain, and beginners can’t spot it. They first get lured by high returns and proactively cooperate by downloading a fake wallet. Small transfers in the early stage may seem fine, but once a large amount is credited, the fake wallet will lock the account and make you pay the so-called “guarantee deposit” to unfreeze it. Then the scam operation turns into a “pig butchering” scheme—constantly demanding more deposits—until you’ve drained your entire savings and only then do you realize what happened.

With all that said, what I want to remind everyone is this: don’t believe in overnight riches. Before you’re pulled in by high-return promises involving cryptocurrencies, scammers may already be targeting your principal. Keeping an extra eye on things matters more than anything else.
