Dear experts, I have a question for you. I retired from the scene in 2021, and this year on May 18 and May 21 in Shenzhen, I purchased 523 oil and 550 oil respectively at a certain easy exchange, preparing to re-enter the scene. Just on May 21, there was a problem with the oil I bought. At that time, I made the payment through Alipay, which was linked to my bank card, and the funds were deducted from the bank card. On the morning of May 22, Uncle Hat called multiple times saying I was scammed and asked me to make a record, but I said I was not scammed. After a simple record was made, Uncle Hat told me to stop playing, and I agreed. Then, a week later, during this period, I received daily calls demanding that I sell my U and exit the software. On the evening of May 27, I was forcibly called to make a record and was required to sell the cryptocurrencies I had at that time, which I sold all and the funds were credited to Alipay. The response given was that although this is not illegal, many people complained that if I did not withdraw the funds, they would have no explanation. Whenever I logged into the software, they would receive a network alert. To cooperate with their work, I sold them, and they never contacted me again. Now I want to buy some U and digital assets through C2C on Binance. How can I avoid the risk of being monitored again? Thank you all.
