How long does flux last?

Could you elaborate on the duration of the effects or validity of the term "flux" in the context of cryptocurrency and finance? Specifically, are you referring to the duration of a price fluctuation, the longevity of a particular trend, or perhaps the lifespan of a cryptocurrency project? If it's related to market fluctuations, is there a typical duration that a surge or decline in value tends to persist? Or, if it's about the sustainability of a financial product or service, how do we assess its long-term viability? Clarifying the specific meaning and context of "flux" would help provide a more accurate response.
