Can you imagine? If all the gold on Earth were melted into a sphere, its diameter would only be 32.6 meters—roughly the height of a small building. The total value? 46.7 trillion dollars.

This ball is divided into two layers: 21.63 million tons that have already been excavated and are lying in the vault (valued at 29 trillion dollars based on the current gold price of 4166 dollars/ounce), and 13.31 million tons that are still buried underground waiting to be mined (valued at 17.7 trillion).

Standing in front of this sphere, you will find that it is about the same size as the iconic white buildings of a certain country's capital. This little thing supports humanity's wealth belief for thousands of years.

Why is Bitcoin often compared to gold? The answer lies in this ball - true scarcity is never a marketing gimmick, but a physical law.
