#以太坊大户持仓变化 Received a call from an unknown number: "Hello, this is the Public Security Bureau. We want to understand your virtual currency transaction records..." — instantly, your mind might go blank. But don’t panic; this situation is no stranger to many seasoned crypto users. The key is how to respond—cooperate appropriately to clarify the matter without causing yourself additional trouble.

**First Principle: Recognize Legal Boundaries**

First, you need to understand—your transactions are not illegal by themselves. Personal virtual currency trades are not prohibited by law; the issue lies in the source of the funds. If you received money from money laundering or scams, you will have to face the consequences of using it. So when communicating with the police, emphasize: I am only conducting legitimate transactions on regulated platforms or with individuals, all operations are compliant and transparent, and I have no intention of participating in illegal activities. This helps investigators quickly determine whether you are an innocent trader or a problematic participant.

**Second Key Point: Don’t Get Excited When Asked to Refund**

If the police point out that the funds you received may be problematic and ask you to cooperate in returning them, do not react defensively. What you need to do is—stay rational, communicate proactively, and state "I fully cooperate with the investigation; whatever needs to be done, I will do." Then, proactively provide all transaction details, transfer records, chat screenshots, and other evidence. The more cooperative you are, the smoother the resolution, and it’s less likely that other accounts will be frozen. Conversely, if you resist stubbornly, small issues can easily escalate into big problems.

**Third Detail: Account Freezing Has Differences**

Pay special attention here:
- If you are ultimately found to have directly participated in illegal activities, all your related accounts may be frozen.
- But if you only conducted normal transactions and happened to receive problematic funds, usually only the account that received the funds will be frozen.

This distinction has a significant impact on your future life. The key point remains: cooperate with the investigation, and you won’t leave a criminal record. But if you resist or oppose, the situation changes, and the measures taken will escalate.

**Three Self-Help Tips**

Ultimately, every virtual currency transfer carries risks. Instead of reacting passively after the fact, it’s better to prepare in advance:

1️⃣ **Verify the other party’s identity** — it’s best to deal with verified traders; high-priced offers from strangers often hide traps.

2️⃣ **Trace the flow of funds** — ask clearly where the money came from before trading; legitimate sources are the safest.

3️⃣ **Be cautious with wallet addresses** — do not transfer to unknown addresses; once on the blockchain, information cannot be withdrawn.

In markets like $BTC , safety always outweighs quick wealth. Protect your assets from freezing or being caught in scams—that’s the first lesson for long-term survival.
