Well if you were to ask me it would be much better to save the money in a bank than investing it. Specially if I'm not in badly need of money but if I'm i typical type of individual who's thinking is to double my money i would definitely try to invest it.
Saving is good but for me, investing is better especially if you will just save in the banks. Savings in the banks will only get very little interest and it is taxable and subject for inflation. At the end of the year, instead of gain, your savings will have a lost due to those things.
