Forex is a simple and easy form of investment. You only need to join a trusted forex exchange and have a license. The strategy is the same as other types of investment, buying at a low price and selling at a high price. The time to invest is very flexible. Investors must also choose the type of foreign currency that is widely traded, such as USD, EUR, YEN, GBP etc. Furthermore, investors also need to read international currency news, because foreign exchange is highly dependent on the world economy and the government.
