If you're being practical, buy a gold for a good and trusted investment because that's a physical quantity. If there's a huge crisis in our country, lock down of internet, servers shutdown, and war, probably this gold might help me to bring me up again.
The problem is that physical gold might be a pretty bad investment. If you have a gold bar in your house then you should carefully watch over it because any tiny scratch will cause a significant price decrease while buying a "virtual" gold still can't guarantee 100% safety during a financial crisis. Also in case of any military conflict even physical gold won't really help you.
