Spot electronic transaction is the electronic transaction of products, but the physical object can be extracted. It is a high-risk and high-return investment, but the risk is controllable, and the controllable risk is not that big. For people who don't understand stocks and futures, they can also do it, because it is very simple and the products are single, unlike thousands of products available in stocks and futures. For first-time investors, how to choose stocks is a big trouble, and a single spot gold and silver product is much easier.
