Although both are valuable assets, there are significant differences between them. Gold has been regarded as a precious resource by humans since ancient times but with the change of eras there has been a great change in the needs and preferences of humans. Nowadays people give more priority to bitcoin than gold. Because they can't give maximum security even if they want in case of gold. Due to physical existence of gold, it is not portable. On one cannot hide it. But Bitcoin is an asset that is not a problem when kept in a wallet. If there is good security then there is good advantage using Bitcoin.
