How to buy, use and exchange cryptocurrencies safely and without leaving a trace

First of all, I am a businessman in this forum. It is my first day to register. Please help me. .
I accidentally came into contact with a customer who was Chinese and wanted to convert RMB into U.S. dollars or USDT. This customer’s official background made it even more difficult for ordinary businessmen to handle.
I have helped foreign customers handle this kind of work before, and I thought it was very simple. Little did I know that the nightmare had begun. . .
It should be that the digitization of the RMB has made the situation worse. Traditional methods are completely unworkable. Even in Hong Kong, a so-called free place, during this period, the owner of a currency exchange shop was arrested. Instead of assisting in the investigation, he was directly arrested.
Exchange shops are an industry that raises many questions that are very useful to us. We will have the opportunity to elaborate on this later.
The Chinese also have a foreign exchange limit of 50,000 U.S. dollars per person each year. They used this method to transfer funds one by one, but now this method works well because it is a trap that will directly send you to jail.
Can I use the credit card? Visa Master World Pass? ? Sorry, in China their credit card is called UnionPay card. UnionPay cards that are linked to Visa Master cannot be used on foreign websites. To put it simply, even in 2019, Google couldn’t bind it.
It was in this desperate situation that I discovered that there was a way to buy cryptocurrency in mainland China without proof of identity. . And there is absolutely no trace of it. Of course, I can’t disclose it here. If you need it, you can email me or send me a private message.
Someone who desperately needs equality and justice. I am deeply moved by the ideas that cryptocurrencies represent.I hope that everyone also has a fair and equal opportunity to use the so-called asset information news or freedom.
This is the second time I have posted this topic. Please forgive me for one thing because my native language is not English, so my grammar and even paragraphs are also very bad. Thank you just now because my brother brought some pointers. If there is anything wrong, please include it.
