There’s a red line in the crypto world that you absolutely must not cross. Don’t think you’re far removed from the law—it can happen with one careless move. Never casually exchange USDT or anything like that with other people, especially anyone involved in MLM scams or pig-butchering schemes. If your account gets frozen, all your bank cards could be implicated. Most importantly, your passport and other documents could be confiscated, and you could be kept under restrictions for a long time.
