I don't think it will happen soon, at least. No matter how it sounds, but it takes a lot of time, and in general it is unlikely to happen, because for many gold is still more valuable, because it exists physically.
Bitcoin can be used as a currency on 2010 when Laszlo bought 2 pizza with 10,000 Bitcoin.
Bitcoin has been accepted in many online marketplaces.
Bitcoin already have many investors from institutional and government.
Bitcoin has been accepted as a legal tender in 2 countries e.g. El Salvador and Central African Republic.
Bitcoin already prove it can survive for 13 years so far, unlike shitcoins who died after 1-2 years.
With those achievement of Bitcoin itself, how you can say it wouldn't happen soon and unlikely to happen? I guess you're come from where Bitcoin were banned in your country, that's why you didn't see so many update, development and adoption of Bitcoin.
Talking about how valuable an asset because it just have a physical appearance, you're didn't understand about Bitcoin at all.
