Chinese mainland's current foreign exchange market has not been liberalized, while Hong Kong's foreign exchange market has just begun. At present, there are hundreds of foreign exchange platforms, but less than 50% of them are formal, and the supervision of most foreign exchange platforms has no practical effect. At present, the regulatory platforms of British FCA, American Futures Exchange and Australian ASLE are still formal.

The Australian dollar is regulated by FCA in the UK. I tried it for three months with a small amount of money, and I felt ok.
