i think invest is the best option ,because if you invest some money you will get more and of course there have equal risk.But the best option and better is invests money.
It is not the best option, the best option is that you are going to do both things. Because if you know that you are going to get good results for doing both, saving and investing together. Why not try to choose them? It just depends on how you would like to save while investing into something, save your profit for your good.
