Comparing gold to bitcoin IMO is utterly ridiculous. Bitcoin is a stream of electrons in cyberspace. It is akin to a religion, in that it can't be touched, seen or felt. No-one can say that about physical gold.
Gold does fluctuate in value. However, its variation has nothing on bitcoin, which at several stages has lost about 80% of its value, the most recent being late 2022.
I'd agree property is a good investment, although as I type there are quite a few mortgage holders in Australia under extreme stress.
