Recently, I’ve noticed more and more people around me getting scammed, especially in the area of U coin scams, which are truly hard to defend against. It takes five minutes to deposit $500k into a bank, but clicking on a stolen U link can be gone in less than a second—that’s how big the difference is.

Domestic scammers have now fully upgraded from traditional telecom fraud to virtual currency scams, with increasingly sophisticated methods. I’ve observed that the main reason is that virtual currencies are not protected by law domestically. When victims report to the police, they often don’t even know what USDT is, and some directly tell you it’s not protected, let alone file a case. So scammers have shifted their target to virtual currencies, because the risk is low and the profits are high.

Recently, I’ve summarized the three most common U coin scam tactics currently affecting the most people, and you really need to be careful.

The first is QR code contract authorization to steal U. Scammers will send you a QR code during a transaction that looks like a transfer, but it’s actually a smart contract controlling your wallet. The key point is, any QR code that tells you to transfer to a third party to complete the transaction is 100% a scam. I’ve tried analyzing these U-stealing QR codes, and they turn out to be a third-party redirect link, whereas a normal QR code would just reveal a wallet address. This scam is especially easy to fool beginners; they get dazzled by high returns, and even after being scammed, they still foolishly thank the scammer.

The second is clipboard virus, which is truly malicious. Someone told me before that once their Windows computer copies a Bitcoin address, it gets replaced, but other text remains unchanged. Scammers will send you some seemingly enticing Trojan virus files; just download and open them, and any transfer links you copy afterward will be changed to their wallet address. Even if you copy an address ending in 123, it will paste out as 567. Preventing this scam is simple: never click on unknown download links or unfamiliar files.

The third is fake wallet U theft, which is a major scam zone. Because cold wallets are open source, it’s not hard to imitate one. The scammers’ tactics are layered, and beginners can’t see through them. They first lure you with high returns, prompting you to voluntarily download a fake wallet. Small transfers in the early stage are fine, but once you have a large deposit, the fake wallet will directly block your account and demand a deposit to unfreeze it. Then it shifts from a scam to a “pig-butchering” scheme, constantly pressuring you to pay, until your funds are drained and you realize you’ve been scammed.

So my final advice is: never believe stories about getting rich overnight. The high returns of virtual currencies are indeed attractive, but before you get drawn in, scammers may already be targeting your principal. The best way to prevent U coin scams is to stay vigilant—don’t download unfamiliar files, don’t scan unknown QR codes, and don’t let high returns blind you.
