Holding is only for those you can afford to take risks for the rainy day and as long as the earth remains challanges are part of human experience and as such so much would tempt one sell some coin. But there is always a short break for every human figure represented on earth where you have little or no need for money but it keeps coming in and that's the best time to invest other than save.
Saving has been the traditional way of planning for the future where people bank their funds in commercial banking sector waiting for when the need to take back from the bank arises even when we had centralized stocks where people could invest in many still thought it was wiser to deal directly with banks other than investing.
Investment is good an idea, but that doesn't mean we should pour out all that comes into our porce into investment and forget that there's a place for savings which investment can't replace in as much as it is important.
Both concept has it's own role and one can't be made to be more important than the other based in theur different role they fulfill depending on the time and the factors that be.
You should make out some good allocation which it would be divided on several parts;
1.Savings (emergencies)
2.Expenses(bills,needs etc.)
3. Investment
Whenever you do earn money then it would really be just common sense on where these amounts should be allocated.
Dont ever forget to set aside for savings yet we dont know on what would happen ahead.
