Yesterday afternoon, I was staring at the market data when my phone suddenly rang - an unknown call, displayed as a landline from a certain place.

After connecting, the other party got straight to the point: "Hello, this is the Cyber Police Team of XX City. Your bank card is suspected of violating regulations related to digital currency transactions and needs to cooperate with the investigation." I almost dropped my mouse in shock.

To be honest, at that moment my mind went blank. My heart raced, my palms sweated, and I began to frantically recall whether I had recently exchanged U in an unreliable place. This feeling is something that anyone who has been in the circle for a while should understand—an unexpected "mysterious call" that can scare someone half to death in an instant.

However, after calming down, I immediately realized something was wrong. As a seasoned player with nearly five years of experience in this field, I've seen this kind of trickery too many times. Today, I will share all my practical experience to clarify a few core issues, so that next time you encounter a similar situation, you'll know what to do.

**Let’s first address the first question: Is buying and selling digital currency illegal?**

Many people panic when they receive such calls, and self-doubt begins to creep in. But I must tell you: personal participation in digital asset trading does not constitute illegal behavior at a legal level.

Of course, there is a premise here - your trading is voluntary and genuine. But at the same time, it's important to be clear about one thing: such transactions are not protected by law. What does that mean? It means you can buy and sell, but if something goes wrong, don't expect to recover your losses through legal means.

A friend of mine suffered a huge loss last year. He was swindled out of more than 600,000 through some off-market channel, and after reporting to the police, they could only register the case.
