Crypto Trader Loses $2.5M in USDT to Address Poisoning Scam — Twice in One Day

The incident occurred on May 26, with the first costly mistake involving the accidental transfer of $843,000 USDT. The trader had copied what they believed was a familiar wallet address from their transaction history—unaware it had been manipulated by scammers.
