Is combo only two things?

Excuse me, could you clarify something for me? The term "combo" is often used in various contexts, but in the context of cryptocurrency or finance, it's not immediately clear what it refers to. Are you suggesting that a "combo" is limited to only two things? If so, could you please elaborate on what those two things might be? Or perhaps you're using the term in a broader sense and it could encompass more than just two elements? I'd appreciate it if you could provide some additional context or explanation to help me better understand your question.
