How much is 4 bits in money?

Excuse me, I'm a bit confused about the value of bits in relation to money. Could you please clarify for me? Specifically, how much would 4 bits be worth in monetary terms? I understand that bits can be used in various contexts, but I'm specifically interested in their financial value. Is there a standard conversion rate, or does it depend on the specific application or cryptocurrency involved? I'd appreciate any insights you can provide to help me understand this better.
