I dont think so. In the end game Gold is still a precious metal and a beautiful thing in the eyes of a person. Bitcoin is a different story as it is a very good way to make transactions so as for the better currency the bitcoin would be best of two as for my opinion.
Definitively NO.
Gold is a physical asset, Bitcoin is a bluff. And there are thousands of "blocks" in the "blockspace" asset that blockchain is. You can clone cryptocurrencies and create your bitcoin anytime.
