What is the stronghold all time high?

Excuse me, could you please elaborate on what you mean by "stronghold all time high"? Are you referring to a specific cryptocurrency or a particular investment asset that has reached an all-time high in value? Additionally, could you provide some context or background information to help me better understand your question? It would be great if you could clarify your inquiry, as the term "stronghold" isn't typically used in the context of cryptocurrency or finance to describe an all-time high.
