How much money is a bit?

Excuse me, but could you clarify something for me? The term "a bit" is often used colloquially, but in the context of cryptocurrency or finance, it doesn't have a universally defined monetary value. Are you referring to a specific cryptocurrency, like Bitcoin, where "a bit" is sometimes used as a shorthand for a very small fraction of a coin? Or is this a more general question about how the value of digital currency is determined? If you could provide a bit more context, I'd be happy to give you a more accurate answer.
