Someone asked, during Binance C2C trading, if a merchant accidentally transferred an extra 'w' to me and I don’t return it, will there be any legal risks? Will Uncle Hat call or show up at my door? Honestly, if you’re buying USDT, you don’t need to worry. Just apply to freeze the merchant’s account. If you’re the merchant, you can only handle it as a civil dispute and file a legal case against them. If you’re the customer and the merchant transferred extra funds to you, the merchant can also apply to freeze your account. But if your account doesn’t have that much money, then the freeze won’t really do anything. In summary, you can choose not to return it. Generally, merchants won’t sue you over 10,000.
