Yes, but scarcity of bitcoin is not time tested. Most people seem to downplay this requirement for being "time tested" along with "scarce". However this is the requirement that drives your decision about how much % of your assets would be in certain form over long run. Would bitcoin still be scarce 20 years down the line? Not sure. Gold? Almost certainly. Also bitcoin is at mercy of technology. Few people knows how system works and where are the security gaps. One doesn't have to be even literate, let alone own a computer, to store and transact in gold.
That's not true at all. If someone gives you a gold bar right now, would you be able to tell if it's real or not? What if, for example, it's steel on the inside coated with a thin layer of gold. Or the gold has a low purity, etc. This is why there are specialists (who are very expensive) who can use special tests to check if it's real (and even then it's not 100%).
It's easy to tell if the Bitcoin that you just received is real or not. (Definitely much easier and cheaper than with gold).
