What is rare all time high?

Excuse me, could you please clarify what you mean by "rare all time high"? It seems like a phrase that's not commonly used in the world of cryptocurrency or finance. Are you referring to a particular asset or index reaching an unprecedented high level that's considered unusual or rare? Or is there a specific context in which this term is being used? I'd appreciate it if you could provide more details so I can give you an accurate answer.
