What is the 3 dip rule?

Excuse me, could you please elaborate on what is meant by the "3 dip rule" in the context of cryptocurrency or finance? Is it a strategy or a principle that investors follow to make decisions about buying or selling digital assets? If so, how does it work and what are the key factors that influence its application? Additionally, are there any specific market conditions or trends that the rule is particularly suited for? I'm curious to understand the nuances and practical implications of this rule.
