Bitcoin cannot replace the value of gold since.
Gold continue to increase its value every now while bitcoin depends on the demand of its users/ investors.
But to think that gold has unlimited supply - it is a big NO because why that the price of gold increases if it has unlimited supply? Come to think the law of demand and supply and your will realize.

But some people appreciate the value of bitcoin as gold - we can not deny that, it's their own perspective.
