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.
Agree. Maybe for now bitcoin is a powerful currency when having lots of advantages than gold. But that doesn't mean gold lost its value. And no one can predict about bitcoin's future, so haw can we know if it exist one day.
I think for a long time bitcoin will begin to cannibalise the gold market, but the two will coexist. There are a number of older investors that will always want to hold traditional gold in their portfolio, but some of the younger investors will prefer bitcoin.
