but if there are an emergency and you need those money, you can't get them because they are locked(if for fixed deposit you mean that) by the bank, also the return per year is very slim
i think it's better to create a business if you want to save money, then just simply invest them, in something that has low risk
for example you could buy things on ebay and sell those at a higher rate somewhere else
i think its better to invest your money 30-40% and save your money 60% to backup if you need anything
because an investment have risk to lose your money.
my example isn't exactly an investment, you could buy stuff that you need anyway and sell those at a higher price on some unknown market online, some random forum is ok too, the only problem is maybe scammers...
