People see gold and silver as investment options mainly because they possess the function of "currency", as Karl Marx’s once said: "Although gold and silver are not by Nature money, money is by Nature gold and silver." To interpret this statement, we need to explore the historical evolution of money.In the course of the development of human civilization, the invention of money marked a significant milestone no less than the discovery of fire, and subsequently streamlined the entire process of economic exchange, enhancing efficiency. This paved the way for the emergence of price discovery mechanism, allowing traders to distinguish high-demand goods from others. Afterwards, markets were formed, laying the foundation for capitalism taking shape.
In various historical contexts, humans have used a wide variety of items as currency, ranging from livestock, crops, shells, and stones, and yet, gold and silver emerged as universally preferred currencies across different nationalities, races, and cultures.This preference arises from the six key characteristics inherent in gold and silver that make them ideal for the role of currency.
