When receiving a call from the public security department asking about virtual coin transactions, many people's first reaction is to feel a tightness in their chest. But as long as you keep a steady mindset and know what to say, most situations can be resolved smoothly.

**Core understanding should be clarified first**

The buying and selling of virtual coins between individuals is not illegal in itself—that's the first point to clarify. What you need to do is to make it clear to the other party that all your operations are completed through legitimate channels or transactions between the two individuals, and that you haven't done anything wrong. The key is to prove that you are just an ordinary trader.

**The attitude is the most important**

If the other party says that the funds you received may have issues and need to be returned, do not try to stubbornly resist. Maintain a calm mindset and proactively present all transaction records and transfer receipts. The higher your level of cooperation, the faster the issue will be resolved, and it will be less likely to involve troubles with other accounts. Those who refuse to cooperate will ultimately suffer the consequences.

**Two Cases of Frozen Accounts**

It is important to make a distinction here: if it is determined that you directly participated in illegal activities, your entire account may be frozen. However, if you accidentally received problematic funds during a normal transaction, usually only the card that received the money will be frozen. This distinction is significant. If you cooperate well with the investigation, generally, you will not have a criminal record, but if you refuse to cooperate, the consequences will escalate.

**The "Three Checks" that must be done before trading**

The risks of virtual coin transactions are not that simple; every transfer may conceal hidden dangers. Therefore, it is essential to develop the habit:
- First, verify the identity and credibility of the other party (real-name authentication is best)
- Check again if the funds are clean.
- Finally check if there are any anomalies in the wallet address and transaction path.

Ultimately, in the coin circle, stability always prevails over quick profits. Protecting your assets from being involved in scams is the biggest win.
