Saving is always the best thing to do
Save money is a bad idea
The best thing is which brings you more profit in the long run. Strictly speaking, saving in a bank on a deposit account is also a form of investing, not very far from investing in, say, the US Treasury bonds. And it is still debatable which is more risky (inflation-wise, before all)...
Saving is important and good idea. Is it better to save money or invest it? its all depend on your goal. If you want to grow your coins or your fiat money then make an investment or you can make a business. But if you want to save your money and you are scared to lost it then you will save it. ITS ALL DEPEND ON YOUR GOALS>
