You should be talking about spot exchange. Without clear supervision, there is no guarantee of reliability. I suggest that you live within your means in this speculative market, and the pure funds are all gambled by market traders.
As for opening an account, you can go to official website or ask the so-called "teacher" or "account opening specialist".
PS: This kind of investment fraud with high returns as bait emerges one after another. I don't know which "third-party beauty" friend recommended you, or the teacher through the "stock live room" I suggest you understand this kind of fraud first. CCTV Integrated Channel has clearly informed investors that it is illegal for the spot trading platform to conduct electronic fund transactions regardless of the provincial approval or the approval of the Ministry of Commerce.
