Commodity investment is a financial derivative industry with strong development momentum in recent two years. The specific trading mechanism is similar to futures, but the risk and entry threshold are much lower, which is more suitable for mass investors to manage their finances. Online trading refers to disk trading. Like stock trading, offline trading refers to the actual delivery and circulation of goods, mainly for traders with industry background. As ordinary investors, they can only trade online. I recommend you to pay attention to Nanjing Asia-Pacific Chemical Exchange, which is a platform for small and medium investors to invest and finance. At least you only need 50 yuan to enter the market, and its disk trend is also very active.
