I like this phrase of yours. It is just basically telling that Gold is traditional, and Bitcoin is already modern.
So for me, the most special feature I can see with Bitcoin compared to gold is that Bitcoin is intangible, which really outstand in our modern days now especially we already have internet.
Gold is older than Bitcoin but both gold and Bitcoin will continue their existences and none of them will kill the another asset. The world population is huge enough with many human generations, and basically the older generations are less likely accept new technologies, new investment assets like Bitcoin while very oppositely, the younger generations will be opened with new technologies like blockchain and new investment assets like Bitcoin.
