Of course.
As you always had, either your family or your business (but this time you're mostly a capitalist and you control a business indirectly).

What you're asking is highly immoral.
You're asking for your wealth to grow without contributing anything, even an investment in the economy.
Clealy this is not good/fair for those who are contributing to society  (i.e. woking).

Instead you should indeed depend on others (hopefully you have while working helped out your parents or you fellow citizens) or be active in the market and thus invest in those who still work (if you want a more individualistic approach)

Thus by storing money in gold or bitcoins for the purpose of an investment you are not only being immoral but hurting the economy since you are withdrawing liquidity from the market. Having gold as a reserve has some moddest value to the economy in case a fiat currency is horribly miss-managed but that's far from the point. Nations and corporations who have it as a reserve do not have it as a investment and they have alot of other currencies to.
