Bitcoin in existence - 11 years running
If you still want to compare gold with bitcoin, it's upto you! Gold has been used by the banks worldwide to keep as a cash equivalent for unforeseen times. Bitcoin is not yet adooted by banks for any such reasons.
Looking at the current situation, Gold stays way ahead than bitcoin or any other cryptos to be considered as a safe heaven. Hope you have got your answer.
You already posted your own debate against your own statement. Bitcoin is simply young, but it's already a better safe haven than Gold. Self-sovereign, censorship-resistant, portable, borderless.
It will take time for everyone to see it.
