What does overarching goal mean?

Could you please explain to me in simple terms what the term "overarching goal" signifies? I understand it's used in various contexts, but I'm particularly interested in how it applies in the realm of cryptocurrency and finance. Is it referring to a single, overarching aim or objective that guides all actions and decisions within this field? If so, what might that goal be, and how does it influence the strategies and approaches adopted by professionals in the industry? Thank you for your clarification.
