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
Yes you're right but they have no difference when it comes in value. They have the same value as people knows about that. The thing is gold has already stronger foundation than bitcoin it seems that people are more gives attention in gold because from now not all people accept bitcoin as payment or money.
