This is a silly question. Of course you MUST invest your money. If you put it under a mattress it will lose value due to inflation and government printing of new money. Some countries have it worse than others, however a properly diversified portfolio will go up over the long term fast than inflation. It's important to invest in uncorrelated assets. You don't want one country's economy to determine the outcome of all your investments. Invest in interesting things that you understand, including antiques, the outcome of legal disputes, property and recession resistant industries across the globe. If you are young take good risks.
