An all-time high or ATH denotes the highest price and market capitalization that a particular cryptocurrency has hit in its entire period of existence. For instance, Bitcoin ATH will depict the highest price the leading cryptocurrency has ever traded at since it came into being in 2009.
The ATH is a measure of the asset’s potential and is a common term for all financial instruments beyond cryptocurrencies. However, keep in mind that the all-time high value may or may not be breached in the future by the asset, especially in the highly volatile cryptocurrency market.
