Gold does not have a clearly total supply like Bitcoin.

It is easily portable like Bitcoin.

You need to have vaults to store gold bars.

You can not send gold from any wallet you control fully. You have to rely on accounts in banks, vaults etc to store or send your gold.

Bitcoin is light, portable, controllable with your private keys and its total supply is unchangeable. 21M Bitcoin will be mined till 2140. No more Bitcoin to mine after 2140.
