Whether it can be done in China is not clear, but many people are doing it, which belongs to the gray area. However, as the process of marketization in China is getting faster and faster, I believe it will be completely open soon. At present, there are no gold investment companies in China, only Hong Kong and foreign countries, with offices in the Mainland. I'm also doing gold now, on condition that you open an account with a gold investment company or a foreign exchange company. Generally, opening an account is free, and the minimum deposit can reach $300, which means you only need $300 to trade, but gold is traded on margin. The greater the amount of funds, the safer it is. The risk is much greater than that of stocks, but the income is also much higher. Like this Friday's market, it's normal for you to double in a day. I made almost 80%. You can talk to me in detail if you are interested.
