The value of the bitcoin is the money invested in it that alone can be used for something where the need for transactions aren't high, as an example for large international contracts.
I don't know anyone with just the slightest understanding of bitcoin who believe it's a currency anymore.
People buy Bitcoin because of it's volatility and crazy growth.
Gold could survive wars, you can pack small fortune to take on person, it's recognized by everyone.
I just don't see how Bitcoin fits the picture here.
People mined gold because it was very valuable, gold have also been doing it's ups and downs the same have currencies historically (before the central banks).
Bitcoin is gold for the digital space. Bitcoin can survive any one company or institution going down it can survive wars too.
Bitcoin is 9 years old gold is thousands. Golds value could easily go to zero in the future.
Most bitcoins are in the hands of people who didn't buy beause of it's growth but because they believe it ads value to the digital space.
