What are all time high?

Excuse me, could you please clarify what you mean by "all-time high" in the context of cryptocurrency or finance? Are you referring to the highest price ever recorded for a particular asset, such as Bitcoin or a stock, since its inception? Or is there a specific aspect of "all-time high" that you're curious about, perhaps in relation to market trends, investor sentiment, or other factors that may influence asset prices? I'd be happy to provide more information or answer any questions you may have.
