Precious metal mainly refers to eight metal elements, including gold, silver, and platinum group metals (ruthenium, rhodium, palladium, osmium, iridium, platinum). Most of these metals have beautiful colors, strong chemical stability, and are generally not prone to chemical reactions with other chemicals. Precious metal investments are divided into physical investments and electronic trading investments. Among them, physical investment refers to the process of investors buying low and selling high to earn a price difference while being optimistic about the precious metal market. It can also be a hedging measure taken when the economic prospects are not optimistic, in order to achieve the preservation and appreciation of assets. Electronic trading refers to buying or selling precious metals such as gold and silver based on fluctuations in market prices. This type of trading generally involves leverage, which can be used to obtain larger returns at lower costs. With the intensification of the threat of inflation, the turbulence of the global economic situation, and the outbreak of the world financial crisis, the demand for precious metal investment with hedging functions has shown an explosive growth trend. Due to the high liquidity and value preservation of precious metals, they can resist currency fluctuations and price increases caused by inflation
