Bitcoin has a just as relevant, or more so, actual use in buying drugs and frowned upon things on the internet, escaping government restrictions on money, etc.
Gold has those same uses but at an international level and is generally approved of. The gold may never actually move, but ownership will transfer between countries.
But you have to use a middleman or intermediary. The genius of bitcoin was when Satoshi removed that and solved the double-spending problem in a decentralized way.
