Assuming you mean the electronic form of fiat, it's not a good fit for microtransactions because of the fee requirements. A digital currency can be used for much smaller and frequent transactions. Not Bitcoin and most major ones, but there are currencies optimized for real-time transactions with minimal fees, so it is possible.

It's a shame that the cryptocurrency stigma doesn't allow legitimate uses of the technology to enable novel business models and user experiences. But keep downvoting me because you disagree. :)
