That's true. If you're looking to gain your money you have to invest it and work for it.. it's risky and need to focus on.. saving money let only make your money sleep in a bank and nothing happens they may some interests but not too much as compared to investing it.
i think saving money in a bank is not good idea because the interest its really small depend on the fee administration and we can not expecting to get much of profit with this
While I generally agree that bank deposits can hardly beat inflation, not even speaking of getting decent profits. Nevertheless, not all animals are born equal. Many banks allow to open a multicurrency account within which you can freely convert between the currencies that this account was opened in. Indeed, the currency spreads are wide and usually start with 1% (the smallest I've seen), but, on the other hand, you don't pay any fees for conversion and even get some interest on the amounts held in this account at the end of the day...
Basically, you have a sort of a spot currency exchange like Forex in your bank but without typical risks associated with it
