Many of the brothers trading U have never really thought about one thing: if one day they are called in for a "chat," can they actually explain things clearly?

The general process isn't as complicated as you might think. At the start, they will usually give you a psychological expectation, like that phrase: "Virtual currencies are not protected by law, you understand that, right?"

Many people get nervous, but you really don't need to. The point isn't to scare you; it's to set the boundaries first: you voluntarily participate in the transaction and bear the risks yourself, but that doesn't mean there's something wrong with you. Just answer normally, don't panic, and don't make things worse by over-explaining.

The truly critical step is the second one, which is about the source of funds.

If your bank card is involved with incoming fraud-related funds, being called in to explain the situation is actually a standard procedure. The key isn't whether you did it or not, but whether you can clearly explain the transaction—such as whether the C2C orders, transaction history, and records match up. What you should be most afraid of here is speaking randomly or resisting. Just cooperate normally and state the facts clearly.

Refunds or fund processing, in essence, are also procedural issues that can't be resolved by arguing or hiding. If you have complete transaction records, you can generally go through the explanation and processing procedure, provided that your own transactions are normal.

The third point is what most people care about: whether it will leave a criminal record.

In reality, it's not that exaggerated. As long as you can provide a complete transaction chain and prove that you were not subjectively involved in money running or money laundering, you generally won't end up on the criminal track. It's more about risk control and bank card restrictions.

Another detail is that the level of the card matters, and the impact differs.

Some cases involve fraud funds coming in directly, which can trigger risk control on more cards; others are just a single abnormal transaction, freezing only one card without spreading.

To be honest, the U path itself is not transparent, especially the OTC part—the risks are always there. Don't touch those funds with unknown sources or abnormal prices. To save a small price difference, you might later affect your bank cards, credit, or even your life. That trade-off just isn't worth it.

To sum it up in one sentence from Brother Cat: you can play, but stay clear-headed—don't gamble on luck, and don't cross the line.
