I prefer to invest because I can get profits on it while saving money. For me I save the half of my money and the half to invest. Investing is risky because you dont know who or where you invest, I usually invest personal to insure that my investment is safe.
But I think saving money is not bad too, Yeah it's better for us to investing, both saving money and investing it is necessary for us.
If we want to grow more our money then we need to invest it. Then when it grow, it's to save it and re-invest it again.
