Of course, that is already a given.
And yes, the inflation rate vs the interest rate that we usually see banks offering nowadays makes putting your money on banks not that appealing. Which makes diversifying your investments is a better choice and putting some into gold is one of them. But the thing is, on a daily basis, it is pretty difficult to use gold in exchange for necessities and services that we need. And the same thing goes for emergencies that requires you to have money to spend fast. Which is why I told OP to "just keep an amount that is enough for you to use in your daily life plus emergencies on bank accounts and keep the rest on investments like gold, silver etc."
