As a rule, money saved in the bank is money you are losing. Because of inflation, money you have now will be worth much less within a year or so, and the interest in bank savings account can't keep up with the inflation rate. The only thing banks are good for is keeping liquid money. Other than that, find growth elsewhere.
And with you money in the bank, they are the one who benefits from it. Because they are using it for loan offers and the interest you will be earning from them is only a centavo coming from the profit they made. When you have saved money, its also good that do some investments like bitcoin.
The interest is pretty much non-existent. They are earning way more from lending your money to other customers. You only get a few cents - pretty much nothing is left when they also charge their holding fee.
The only benefit you get from storing your money there is that is money you can quickly take out (liquidity) unless the gov't or bank have some problems (like what happened in Greece). Having some amount of money in there allows you to use a credit card, from which your credit score would be based for car and home loan. Other than that, you'd rather not give them your savings.
