Do you get cash from Bitcoin?

Excuse me, could you clarify something for me about Bitcoin? I've heard a lot about it recently, but I'm still a bit unsure about how it works. Specifically, I'm wondering - do people actually get cash from Bitcoin? If so, how does that process work? Is it straightforward, or are there certain steps or precautions one needs to take? I'd really appreciate it if you could shed some light on this for me.
