Will he invest in the crypt, or open a deposit, or does it make sense to buy solid metal?
I see savings with the banks as for liquidity only or for your emergency funds only, if you want to make profit out of it then better to use the money to invest on a good market, like stocks, crypto or even with gold. You have to understand that savings can’t make you that much because of the inflation. Always have your emergency funds ready and never use it for your investment because you might touch it once you badly needed the money.
