How much is headless?

Excuse me, as a cryptocurrency and finance professional, I often encounter discussions about the valuation of various assets. However, I've stumbled upon a somewhat puzzling term recently: "headless." Could you please elaborate on what exactly "headless" refers to in the context of finance or cryptocurrency? Is it a specific metric for valuing digital assets? Or perhaps it's a colloquial term referring to a certain trading strategy? Clarifying this term would greatly assist me in better understanding the nuances of the industry. Thank you for your time and insight.
