Well in my opinion, bitcoin will never be equal to gold because gold has physical value and represents for the whole economy while bitcoin is just numbers. One possibility for that to happen is we lose all our gold
Exactly we shouldn't compare this two because they are too different from each other. It will also depend on the user if he is a bitcoin user or gold user. Because like me as a bitcoin user im going to hold more btc than gold because i have much knowledge about it.
