How to save savings in inflation, there are many deposits provided by the bank, but banks often go bankrupt, does it make sense to buy gold? How is gold bought in a bank and interest is issued on it?
I wouldn't say they "often" go bankrupt. But where are you buying your gold? Are you going to store physical gold with certificates? Are you storing it in your home? Are you going to buy a safe or how are you keeping it secure? You can't really store it in bank, like you said, you are afraid that they are going bankrupt. If you are buying commodities from stock exchanges? What if those exchanges go bankrupt?
Imho you can't really live your life scared that banks will fall. And why not buy bitcoin instead? That's more liquid to get rid off and easier to store.
