Saving - is putting money aside, bit by bit. You usually save up to pay for something specific, like a holiday, a deposit on a home, or to cover any emergencies that might crop up, like a broken boiler. Saving usually means putting your money into cash products, such as a savings account in a bank or building society.
Investing - is taking some of your money and trying to make it grow by buying things you think will increase in value. For example, you might invest in stocks, property, or shares in a fund.
Exactly if you have a lot of money that you won't spend for a long time you invest it, you only need a relatively small amount of savings for specific things. Savings don't earn you much (a little bit of interest is all).
if saving can give much of profit then maybe saving is worth but as we know, if we only saving small amount into the bank, then our profit is not much and maybe its end up for the fee. but for investment, if we choose the recommended programs, then i think in the long term, we can reach maximal profit. but i will say that both saving and invest is really good to do.
