According to statistics, the total market value of global gold currently exceeds 8 trillion U.S. dollars. If the market value of Bitcoin exceeds 8 trillion U.S. dollars, the value of a single Bitcoin will exceed 400,000 U.S. dollars. This is just a judgment on Bitcoin's value as a "digital gold".
Why do many people call Bitcoin "digital gold"?
I'm sure some people refer to bitcoin as digital gold, because they don't analyze it as far as you do, they only look at the basic physical aspects of bitcoin like limited supply and to own it we also have to do mining, if we look at it from this physical only, it's not wrong if they analogize bitcoin as gold in digital form, and some people also claim that bitcoin is better than gold.
