Of course, your question can't be generalized, because different countries have different questions for you.
For example, among developed countries, the United States and Australia are special, and their countries charge personal income tax on foreign exchange speculation and stock index futures, and they are relatively high.
Britain, New Zealand and established European and American powers do not charge any fees for individuals to speculate on foreign exchange and stock index futures. Therefore, as we all know, Europe's foreign exchange finance industry is actually an international center and center of gravity.
In short, individuals who speculate in foreign exchange in China are not required to pay taxes.
