There is quite some recent history of sustained value and perhaps the gold price also fluctuated wildly in the beginning until it settled. I can convert BTC to Euros from my lazy chair, try doing that with gold. Gold also has substitutes, almost any element of chemical substance has value but they differ in their practical use. Gold is shiny and chemically stable and not to abundant but Iridium can just as well function in the same way. As can oil, etc. I'll argue that gold you keep at home is easier to steal than my BTC, which are also at home but you need to break in and get my computer or you have to be a pretty good hacker.
