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.
Its true that gold is more precious that bitcoins but it was very hard to obtain gold and it is only for the wealthy people. We are so very lucky that in our generation there is bitcoin that exist and we have a way to earn this coin so we can live a happy life each day and never worry about the future.
