On the day I was interviewed by the police, I truly understood that the cryptocurrency world is not illegal, but it is definitely not a place without issues. Last year, a fan called me in the early morning, his voice trembling: Brother, I was called to the police station, they said suspicious funds entered my account... He almost cried and asked me: Boss K, am I going to jail? At that moment, I pulled him back to reality with one sentence—Calm down, this does not mean you broke the law. Too many people are scared by the phrase 'virtual currency = illegal,' but the truth is: The government has not banned cryptocurrency trading, but it has clearly stated that asset risks are borne by individuals, and if something goes wrong, there is no legal protection. It's like you can walk on a dark road, but if you fall, no one will help you. You haven't broken the law, but you must understand the rules and maintain your bottom line. Later, the police asked him: 'Why are you willing to refund? Have you participated in money laundering?' I told him to stay calm and just respond honestly: 'I am willing to negotiate a refund, but that does not mean I am guilty.' Refunding money is not an admission of guilt; it is to buy time and opportunities for account unfreezing. Many people end up missing the chance to remedy their situation because of panicked emotions. Some are most afraid of 'not cooperating will leave a record,' and I can clearly say, don't believe in rumors: as long as you can prove you are not a suspect and actively cooperate with the investigation, the police will not leave a record, nor will they freeze all bank cards. However, be cautious; if identified as a first-level involved card, the consequences will be serious—after the central bank reports, all accounts will be locked, and even the savings card for daily consumption cannot be used; second-level cards do not need to panic excessively, as they can generally be unfrozen after clearing suspicion. The cryptocurrency world is fraught with risks; many people haven't learned to read K-lines before they have already been taught a lesson by reality. Don't think that just because you haven't touched dirty money, everything is fine; many suspicious funds go through multiple hands, and you have no way of knowing the source. Remember my advice: Don't touch money you don't understand, and verify money that comes too quickly. You don't lack that little profit; what you lack is stability. I have been in the cryptocurrency world for eight years, seen the frenzy of getting rich quickly, and also witnessed the embarrassment of being interviewed. Those who can stay for the long term are not those who earn the most, but those who are clear-headed, know how to avoid pitfalls, and maintain their bottom line. I only deal in actual transactions and do not play with virtual ones. Friends who want to avoid pitfalls steadily and profit steadily, do not wander alone in the cryptocurrency world. Keep up with the rhythm.
