I had seen something related, but I hadn't delved into the subject. Until I felt like a millionaire for a millisecond.
Yes, when I opened my wallet I found 4 million USDT. "Fake" USDT.
If you don't know USDT (Tether) is the world’s largest stablecoin by market cap. With its 1:1 peg to the US dollar and the convenience of cross-border transfers. Sadly it has become one of the most favored tools for scammers.
Below I break down the most prevalent USDT scams.
This is currently the most frequent and most damaging USDT scam. Scammers deploy bots to monitor large USDT transactions on the blockchain. Once a target is identified, they use vanity address generators to mass-produce phishing addresses whose first and last few characters are identical to the victim’s frequently-used receiving address. Then, using the smart contract TransferFrom function, they send a 0 USDT transaction to the victim, planting that trap address in the victim’s transaction history. Later, when the victim sends USDT again and habitually copies an address from their history, the funds are transferred into the scammer’s wallet.
In 2025, a trader lost 50 million USDT this way — one of the most expensive “copy-paste” mistakes in crypto history. The same year, prosecutors in Guichi, China, prosecuted a "vanity address attack" case in which the defendant illegally obtained more than 3.5 million USDT from victims by matching the tail characters of addresses.
Scammers claim they can use “flash loan software” to generate temporary USDT balances. These fake coins can be moved between wallets and shown on block explorers, but allegedly disappear automatically after about 16 days. In reality, these so-called tools are outright scams — victims who pay between US$50 and US$500 for the software either receive a useless interface showing fake balances or have Trojan programs installed that steal their private keys and drain all their assets.
This is the one that make me feel millionaire for a milisecond. Scammers deploy fake contracts on non-Ethereum main chains using the exact same name and symbol as the official USDT. By exploiting the fact that wallet apps truncate the displayed address, the token appears identical to the real one. Victims only discover that “token verification failed” when they try to deposit it at an exchange. The FBI issued a specific warning about this in 2024, noting that criminals send fake tokens to build trust or to trick victims into transferring funds to scammer-controlled addresses.
Pig butchering is a hybrid “long-term romance + investment fraud” scheme. Scammers approach victims on Tinder, Facebook groups, or even second-hand furniture groups, spend weeks or months building emotional trust (“fattening the pig”), and then introduce a fake cryptocurrency investment platform (“slaughtering the pig”).
Using bait like “1.3%–2.6% daily interest,” these schemes pay early investors with money from new investors and eventually collapse when the capital flow breaks. In May 2026, the DSJ exchange Ponzi scheme collapsed, involving over US$150 million. Active since 2025, it laundered more than US$92 million in the week before its implosion. Investigator ZachXBT worked with Tether, Binance, OKX, and U.S. law enforcement to successfully freeze more than US$41.5 million.
In Cuba one of the biggest crypto Ponzi schemes was TrustInvesting.
Criminal gangs recruit “runners” on encrypted messaging apps like Telegram, instructing them to collect cash from victims in person and then convert it to USDT for transfer overseas. Many participants mistakenly believe that “just running an errand” does not constitute a crime; in reality, it constitutes the crime of concealing or disguising criminal proceeds.
Here enter the offers like “free USDT airdrops,” “refund compensation in USDT,” or “cheap USDT for sale,” that trick you into scanning QR codes or signing malicious smart contracts. Once signed, the attacker gains unlimited permission to transfer USDT out of the victim’s wallet and can drain all assets instantly.
What makes these scams so effective is the precise grasp of human nature:
First of all, no one is invulnerable. But we can take steps to decrease the risk of being scammed.
| Protection Level | Specific Measure |
|---|---|
| Before sending | Completely verify every character of the receiving address; never judge by just the first and last few digits. |
| Receiving tokens | Verify on Coinmarketcap/Etherscan/Tronscan that the contract address matches the official one. |
| Trading channels | Always use licensed exchanges like Binance or OKX or officials and community probed DEXs or P2P markets |
| Authorization operations | Reject any request that asks you to scan a QR code to authorize or to sign a smart contract. |
| Abnormal pricing | The USDT exchange rate normally stays around 1:1. Quotes below 0.95 or above 1.05 are very likely fake. |
| Wallet choice | Use updated wallets that have address-poisoning detection features |
| Safety habits | Never copy an address directly from your transaction history; re-obtain and double-check the address for every transfer. |
| Legal awareness | Be highly suspicious of “high-paying part-time jobs” such as doorstep USDT exchange or cash pickups; don’t risk criminal liability for small gains. |
