See what you are good at. First of all, you must understand the trading rules of futures and foreign exchange. If you don't understand, it will bring great risks. Secondly, it depends on your capital. If you have a lot of money, you can do foreign exchange futures. If you have a small amount of funds, the risk is high, because foreign exchange needs less funds (high leverage ratio). For example, the euro/US dollar is about 250 US dollars. If it is changed to RMB 2,000, the futures I know are at least close to 6,500.
