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.
Gold is a precious metal that every person are dreaming to have it, and also gold has a historical value.
we don' know when will bitcoin has an end because it is only in online we cannot use bitcoin if theres no electricity/intenet to use too.
