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
Indeed, but every each of them has their own advantages like gold, gold represent the economy if ones country plus it is trusted because it is being used in any transaction for a long time by our ancestors up to us. But also bitcoin is good in earning of profit especially in online investment. Though it is not trusted because of being anonymous, but yet it has a advantages like it has a high voltality compared to gold. Besides I do believe that the more risky the more profit you will get.
