Let's say I have 2.1 BTC And I don't spend it. Will it go up a few cents if I save it? Cause in my wallet I have up to about 50 cents worth of bitcoin. I started up with 13 cents 7 months ago. Now all of sudden I have bitcoins worth 50 cents. What do you call this? I only made that one 13 cent deposit. Nothing else!
It really depends on the person, if you at some point are in desperate need of money, then you can go spend your bitcoin but if not, because you don't know where to use it, just save it for the time being and wait for the right time where you could see a good opportunity to spend it with. Even better if you can invest it so that it will continuously grow.
