What is CAC value?

Could you please elaborate on the concept of CAC value? I'm curious to understand its significance in the realm of cryptocurrency and finance. Specifically, how does CAC value factor into investment decisions, and what role does it play in assessing the performance or potential of a digital asset or project? Furthermore, are there any specific metrics or formulas used to calculate CAC value, and how does it differ from other financial indicators commonly used in this field?
