Dear friends in the crypto world, today I want to talk to you about some practical matters. If one day you need to undergo an investigation due to transaction-related fund issues, don’t panic. There are really just three hurdles; think them through in advance, and you'll feel more at ease when the time comes.

**First hurdle: The boundaries of legal protection**

At the start of an investigation, the other party usually asks: "Do you know that virtual currency transactions carry legal risks?" Don’t be intimidated by this question. It needs to be understood separately. Lack of legal protection doesn’t mean you are breaking the law. In fact, voluntary transactions and mutually beneficial exchanges are beyond regulation; the trouble arises when problems occur, such as being scammed. Law enforcement agencies truly have no direct way to recover your assets. So, honestly acknowledge that you understand this risk and are willing to bear it—that’s the right attitude.

**Second hurdle: The issue of fund traceability**

The core question often points to: "If the funds are deemed involved in a case, why must they be processed?" Understand this—it's not up for negotiation; it’s a necessary procedure. Once the money in your account is flagged as problematic funds, the process is initiated. How to handle it and how much to handle can be negotiated. You can communicate with the other party or even directly contact the victim. As long as both sides reach an agreement, the freeze can be lifted. Resistance is futile.

**Third hurdle: The subsequent impact**

The most common concern is: "Will cooperating leave a record? Can other accounts still be used?" If your attitude is cooperative, your documentation complete, and you can prove the source of funds is legitimate, there usually won’t be any negative record, and other accounts won’t be affected. But pay attention to this classification:

Level one involved accounts are the most serious—they are frozen by both banks and regulatory systems, and all accounts under that name may be implicated. Level two involved accounts are milder; mainly, this card is frozen.

**Final reminder**

Playing U transactions is walking a tightrope in the gray area. Never treat it as ordinary buying and selling of goods. Do your homework on every transaction: source of funds, information about the trading counterpart. Remember this one rule—money with unknown origins should never be touched. Risking your accounts, credit, or even your identity for a moment’s profit margin is a huge loss.
