Listen brother I think you are getting confused with the Bitcoin units .
2.1 Bitcoin very huge amount and then you are talking in cents .
Okay the answer is it doesn't depend how much worth Bitcoin you have the change in price of Bitcoin will eventually lead to change in the balance you have in your wallet.
So if you have Bitcoin worth cents then the change will also be in cents, while if you are talking about 2.1 Bitcoin then even a minute change in the price can mean a lot on that value.
