Yeah both has its own advantages. One needs to pick upon their own necessity of money. If the necessity is in a short run saving is the right one. On a long run investing gives bigger earning.
Yes they have its own good purpose. It will just depend on the person that needs to use their service. But of course the important thing is you are saving your money for your future purposes.
I have both things ,savings for emergency problems,and i am investing to maximize my potencial income,till the moment im very happy to had invested as the returns are coming even slowly but i see the result of investing.You should always explore both options and take the risk around both knowing that you are doing something .
If you want to earn good profits in future then you need to take that extra risk at this stage, as every investment involves certain risks, that is a part and parcel of any investment.
For me it not really risk, Just think about the long term. Suppose the price falls again to 350 then just hold your coins (i.e. don't panic sell) an wait for a year or so. Eventually the price will get picked up again.
