There are two reasons. First, Bitcoin is a non-credit currency ten times stronger than gold. So unless Bitcoin is replaced. Otherwise he must surpass gold. Second, Bitcoin is close to being the ideal non-credit currency, and it is basically impossible to have another non-credit currency beyond Bitcoin. Combine these two points and Bitcoin is bound to surpass gold
we don't need to compare the two. Bitcoin and Gold will be a win-win investment. and neither need to be classified as a superior asset.
if you look at the direction of your statement, it seems you are more towards both as an asset. whereas Bitcoin is oriented to be more of a currency.
gold is more stable than Bitcoin. but Bitcoin has a more volatile value for investors or Bitcoin users to use to get better profits than Gold.
