I think it is better to invest, if we invest so we can get a bigger profit of up to 100% in a short time, remember to save money will not make money being a lot but its value will continue to fall.
If you think that investing all your money will make you a millionaire in a day/month/year or whatever then you are living in a dream. In real life the daily necessities and need of money come in front before we even think of investments. Savings are needed to cope up with that and if you dont have any then you are as good as dead. Investments are important to earn but the sole idea in life is not earning but living life to the fullest and that is where savings will come in handy as well.
