One of the problems with saving your money with a bank is that the small amount of interest you get from them right now does not out pace inflation so you will be losing money the longer you money is in the bank just because of inflation alone.
You would be losing even more money if you account in the opportunity cost of the investments you could have made with the money while it is in the bank.
Saving money in bank is not profitable now as you said inflation rate will kill everything, so it would be a better choice to invest money to gain good returns in future.
