I'll add that if gold wasn't so impractical to transfer, store and verify we would most likely still be using it as a currency way more frequently (even in our inflatuonist systems, it would likely be seen as a more sound money).

Bitcoin improves a lot on all of these properties while introducing other properties (open/public network, borderless, public ledger, etc.). Its supply/issuance has also been much more stable than Gold ever was (and ever will be if we're to believe the predictions of giant mines and even future asteroid mining).
