What is cro all time high?

Could you please clarify for me what is meant by "cro all time high"? I'm trying to understand the significance of this term in the context of cryptocurrencies. Is it referring to a specific point in the price history of CRO, or is it a more general term used to describe the highest price ever achieved by CRO? Additionally, could you provide some insight into what factors might contribute to a cryptocurrency reaching an all-time high? Thank you for your assistance in clarifying this matter.
