1. High value preservation and large appreciation space;

2. More flexible, both ups and downs can be operated;

3.T+0 trading mode, which can be bought and sold on the same day;

The market is open, so it is difficult to have a banker.

Second, the shortcomings:

There are many kinds of investment, and the investment risks of paper gold, gold fund and gold futures are high; If the purchase cost of gold jewelry is high, the repurchase is not smooth. Generally, the tools that can invest in gold are mainly exchange traded gold (ETF) and physical gold or paper gold sold by banks. Gold is a safe-haven asset. When other financial markets are in bad or even in crisis, more investors choose to invest in gold to hedge, and the price of gold is affected by many factors, including war, interest rate, dollar and so on.

Gold is a chemical element with stable chemical properties and hardly reacts with any substance in the natural state. With its golden luster and soft texture, gold can be easily processed into the shapes that people need. Gold is 19.6 g/cm3, which is one of the densest substances and easy to carry. Gold is a scarce natural resource. After thousands of years of mining and accumulation, the stock of gold is only about 6.5438+0.4 million tons. Even in the modern era when mining technology is very developed, the annual output of gold is only over 2,000 tons. These characteristics determine the natural properties of gold.

Gold is favored by people in different periods because of its beautiful luster, natural rarity and excellent physical and chemical properties. In the 5,000-year history of human civilization, no substance has such a close relationship with social evolution and social economy as gold, and has become an enduring currency carrier, a symbol of wealth and identity. Therefore, in the evolution of human civilization, gold has two attributes: currency and commodity, and accordingly, the price of gold is determined by the dynamic equilibrium of its two attributes.

In the period when the standard of money is gold, the price of unit gold is the price of its commodity, and gold is the equivalent of commodity exchange.

In the period of monetary standard or credit standard, the price determination of gold is influenced by the balance of monetary attribute and commodity attribute of gold.

In the evolution of currency history, because the dual-standard currency often has the attribute of insufficient credit currency, currency issuance, like credit currency, is the debt of the currency issuer to the currency holder. When the state power becomes the subject of currency issuance based on double standards or credit standards, currency issuance becomes the state's debt to currency holders. Therefore, when the currency issuer faces political, economic and financial crisis, the balance between the monetary attribute and commodity attribute of gold will move like the monetary attribute of gold, and the monetary attribute of gold will rise to be the dominant factor in the determinants of gold price.
