A user with the address 0xcB80 lost $50 million worth of USDT due to a copy-paste error.

Here's what happened: they first transferred 50 USDT to their own wallet 0xbaf4b1aF...B6495F8b5 as a test to verify the address was correct. But this seemingly cautious move actually gave scammers an opportunity.

The scammer immediately registered a wallet address that mimicked the victim’s address, matching the first and last four characters. It looked almost identical. When the victim accidentally pasted this fake address while transferring 50 million USDT... the funds were lost.

This case profoundly illustrates a key issue: on-chain transfers seem simple, but any oversight can lead to catastrophic consequences. Even experienced users must stay vigilant at all times. It is recommended to develop habits such as double-checking addresses before large transactions or using security tools like hardware wallets.
