Is it better to save money in bank or invest it online, in real estate or maybe gold?
Saving money in a bank is what I would do. Investing is risky and requires time and effort.
Saving money in bank is not a growth related action. It's just a protection to your money. The bank interest rates are always lesser than the inflation rates which would make your money would not be sufficient after next 5 or 10 years equivalent to current worth for a living.
