The price of $BTC has been roughly calculated, and currently the price of one Bitcoin is very close to the market price of one kilogram of gold. However, it seems that owning one Bitcoin is more convenient and rarer. This is because the total amount of gold mined worldwide is about 200,000 tons, which corresponds to approximately 200 million 'gold coins', ten times the supply of 21 million Bitcoins. Additionally, physical gold requires assessing its quality, making actual exchange quite difficult.
