do both for the future...if you'll just save it wont grow,if you will just invest you may have nothing to spend for emergency
Correct. Money should be saved and invested as well. IF we just save our money it's value will depreciate over time. We have to keep up with the world and economy. Investing money is a great idea. As we know money attracts money. But certain sum of money should be reserved for the emergency.
Fiat currency will take at least more decades before it will become loss it actual value for a slight percentage. In that duration of time, I doubt you have now used all your saved money for something really good to support your financial needs and that will include all our savings.
