Generally speaking, gold has an inherent recognized value. In addition to its irreplaceable consumption in industry, many chips, memory modules and motherboards in the IT industry are made of gold. In addition, there is no technical breakthrough in gold mining technology. Most of them are gold panning, which consumes a lot of human and material resources and has a high production cost. The value of bread and milk is to fill the stomach. If you buy some goods just for profit, this is not the intrinsic value. Since the development of bitcoin, the voice of doubt has never stopped. Some people believe that bitcoin has no value. It is a foam, a pyramid scheme or even a Ponzi scheme.
