Are they not 2 sides of the same coin? Investing is saving, and saving is investing...
Spending or Saving would be a question...
You have the point on it, because in crypto currency if you are going to save then you are already investing for your future.
Well that is going to be a good question for spending or saving. And I would go choose for saving and don't spend for the things that you don't need.
So that you are going to have good savings.
