Foreign foreign exchange companies can't go out of business, because they speculate in foreign exchange for gambling (customers' trading software has been tampered with), which is why these foreign exchange speculations are prohibited and regarded as illegal in China.

Because foreign exchange speculation and underground foreign exchange speculation are illegal in China, and because your funds are remitted abroad, domestic laws can't control foreign affairs, so your funds can't be protected by Chinese mainland laws from the moment they are remitted to China. Because your capital has gone abroad, it is very easy for foreign exchange companies (platforms) to take your capital, unless you go to the country where the foreign exchange platform is located and file a lawsuit with it. But do you have enough money to pay for traveling abroad and hiring a lawyer? Foreign exchange companies are actually gambling companies, and many gambling companies are legal abroad, so you should sue a gambling company that is legal abroad. What are your chances of winning? Who do you think can start a gambling company? You can beat them if you want to go to court?

At present, all foreign exchange-related investment companies/institutions in Chinese mainland are illegal companies that speculate in foreign exchange and gold underground.
