The first time you go, explain it and sign a contract. After that, if you can avoid going, do so. The anti-fraud center is extremely annoying. Domestic mobile phone big data has captured your information, and if they think you might be scammed, they will keep calling you.

Today, the police contacted me regarding transaction $BTC , saying that the other party's account is a scam. I told them that I transferred it to him, and it's not my account that's a scam. He asked if I had been scammed, and I said no. Then he said he would come here tonight to verify that I hadn't been scammed. Has anyone else encountered this situation?
