What does inflation mean in Bitcoin?

Could you elaborate on the concept of inflation within the Bitcoin ecosystem? Given that Bitcoin is a decentralized digital currency, how does inflation, typically associated with fiat currencies, manifest itself or is it even relevant? Is there a supply cap that mitigates inflationary pressures? And how does this affect the long-term value proposition of Bitcoin as a store of value and a medium of exchange? I'm curious to understand the economic nuances of inflation in the context of cryptocurrencies, particularly Bitcoin.
