Generally speaking, foreign exchange transactions are based on US dollars. If trading on a foreign platform, the platform will have leverage, such as 1: 100, 1: 200, 1: 400. The greater the leverage, the greater the risk you take, and vice versa. Foreign exchange trading is a kind of venture capital, which involves geopolitics, the control of policies and economic indicators, the establishment of personal trading system and many other aspects, so no one can guarantee or determine how much his rate of return can reach. A skilled and experienced operator (trader) will gain something after years of precipitation in the investment market. A skilled and experienced operator (trader) usually earns 15-30% a year, and some of them reach 100% or even higher, but this "high" cannot be maintained for a long time. Therefore, there is a famous saying in the venture capital community that investment is risky and you need to be cautious when entering the market.
