It does and doesn't.
It does when you are going to invest in the bitcoin.
It doesn't if you are making a transaction or if you're going to gamble with your Bitcoin.
I agree with you , price of bitcoin matters on how people treated it.
If you look bitcoin as your need in your daily life it can be more and much important than any, but if you sees it just something to for fun for sure you do not mind on how it increases and decreases.
