Yes in theory, but it depends on the entry price. If it is too high, it will be lost. What really preserves the value is grain gold, and paper gold is virtual gold, which is only used as an investment.

The gold in this world, in terms of value, is not the dollar price we usually see in the trading market. There are dozens of national currencies in dozens of gold trading markets around the world, such as US dollar, RMB, Hong Kong dollar, Japanese yen, British pound, euro and so on. But the real value of gold is not the change of the relevant currency value, but the weight of gold.

For thousands of years, a certain weight of gold in exchange for a certain weight of grain is the real value of gold currency. From this point of view, in order to avoid the chaos of paper money in the world, led by the US dollar, and the inflation caused by the flood of paper money in future countries, owning or locking a certain weight unit of gold is the fundamental way to preserve the value of family assets.
