Simply put, foreign exchange investment means buying other countries' currencies (not necessarily RMB) and then making money (or losing money) by exchange rate fluctuations. Generally speaking, because the exchange rate fluctuation is generally not particularly large (non-emerging countries' currencies), foreign exchange investment needs to use a large proportion of leverage, ranging from dozens to hundreds of times. At the same time, the factors affecting the exchange rate are very complicated, and the trading hours are 24 hours a day except weekends, so this is a high-risk investment behavior. Most foreign exchange investments are unreliable. There are many so-called online foreign exchange speculation platforms in China. These platforms are either foreign platforms of agents or black platforms of self-built simulation. In short, they are not protected by law. Once something goes wrong, it is difficult for investors to defend their rights.
