Friends who play with cryptocurrencies, there are some things you must clarify in advance. Instead of waiting for problems to come knocking and scrambling, it's better to understand these pitfalls thoroughly now.

**First Point: Legal Risks ≠ You Are Breaking the Law**

Many people get panicked when they hear "Virtual asset risks are self-responsible, law does not protect." But listen carefully, law not providing protection does not mean you are breaking the law. If you and the other party willingly trade, each gets what they need, losing or gaining is just market risk, which is normal. The key is to be clear—your source and destination of funds must be transparent. No need to be overly cautious, but also don’t blindly oppose.

**Second Point: Involving Money Laundering Must Be Repaid**

This is truly critical. If your card is suddenly flagged for suspected involvement in illegal funds, it’s not a suggestion, it’s enforcement. Refusing to refund? Expect your account to be completely frozen, and you won’t be able to move anything. But there is some room for maneuver—how much to refund and how to do it, you can communicate well with the investigators. Sometimes you can even negotiate directly with the victim. As long as the negotiation is proper, the card can still be saved. Stubborn resistance? That’s really foolish. Cooperation is the only way out.

**Third Point: Account Freezing Varies by Situation**

It sounds scary, but the reality differs. If your attitude is cooperative, documents are complete, and you can prove the source of funds is legal and the transaction chain is clear, then after warnings, you won’t get a criminal record, and other cards can still be used normally. But if you encounter a primary involved account? That’s troublesome—banks and police will blacklist you, and all your accounts under that name will be suspended. Secondary involved accounts might be better—usually only that one gets frozen.

**Finally, I want to say**

Crypto trading is like dancing on the edge of a knife; there’s no such thing as a "gray area"—that’s a minefield. You must think through who the other party is in each transaction, where the funds come from, and these details. Accepting money from unknown sources casually? Your accounts, credit reports, and credit history are all at risk, and it’ll be too late to regret.

Instead of gambling on luck, it’s better to follow the proper path from the start. Understand basic compliance knowledge, know which pitfalls to avoid and which ones are absolute no-go zones—that’s the real way to survive longer in this market.
