Precious metals refer to metals that are rare in nature and difficult to mine, so they are expensive.

The so-called precious metals are short for precious metals, and in a narrow sense, they refer to precious metals such as gold and silver. Precious metals in a broad sense include physical investment and non-physical investment. Among them, physical investment refers to the process in which investors buy low and sell high to earn spread income when the precious metal market is optimistic. Or it refers to a hedge taken by investors to preserve and increase the value of assets when they are not optimistic about the economic prospects.

Non-physical investments include leveraged electronic trading investments and bank bills, gold, paper and silver. Electronic trading is a process in which investors decide whether to buy or sell precious metals such as gold and silver according to market price fluctuations, and make profits from it.
