No one, in my view, could give an exact answer to this question as Bitcoin still strives to get an international accreditation, but there are high expectations that Bitcoin will surpass Gold in the future. We can't deny that gold has been used for decades as a safe store value owing to its scarcity and preciousness. However, Gold has these features as there is a limited amount of it. Moreover, Bitcoin has the feature of being decentralized. Therefore, it is a matter of trust that bitcoin should attain so as to surpass and replace Gold.
I think theres a big chance bitcoin can replace the gold because bitcoin will popular in every country because of the good price and we know bitcoin is ideal also for investment so theres a big chance gold will plunge the price and bitcoin will goes up the price because of people investing.
