The question ceases sucw interesting. I think the first common point between Bitcoin and gold is that they are limited, Bitcoin has only 21 million, so is gold. They vary by market, but in general they are not inflation but deflation. Therefore, both Bitcoin and Gold are good investment channels to protect assets against financial fluctuations. Also I think they have in common is rare. A few months ago Bitcoin prices reached an ounce of gold. And now it's twice. Amazing. If I were to choose between Bitcoin and Bitcoin, I would choose Bitcoin because I believe it will continue to increase, which would be a good investment for the future.
I think you are right.
Ofcourse there are many, many differences between gold and bitcoin. But there are also few things common:
* they are both rare
* they are both independent of local (national) economy
* they are both "safe heavens" for investing while the "normal economy" has problems or is expecting problems.
