foreign platforms encountered many obstacles in domestic operation, and Xiaohei platform closed down, but it can't be said that it will be gone in the future, only that it will be relatively high. The intervention of the state also proves that the state attaches importance to foreign exchange trading, and the recent simulated trading of foreign exchange futures listed by CICC shows that if the state wants to build a domestic platform, it must drive out foreign platforms. This is a trend and a process, which will promote the development of domestic foreign exchange trading. It is possible that after trading foreign exchange, you can directly open an account in a formal domestic institution, just like domestic commodity futures, except that the leverage may be relatively low and the capital threshold is relatively high, but compared with the previous foreign platforms, our funds are safe and secure.
