What Is ATH (All-Time High)?

2026-09-10

ATH stands for all-time high: the highest price a cryptocurrency has reached in its history according to a given data source or market. In crypto the ATH figure can differ slightly between exchanges and trading pairs.

What it means

ATH is simply an asset's highest-ever traded price [1]. For example, if Bitcoin rises to $80,000, then $100,000, then falls back to $60,000, its ATH is still $100,000 — until a higher price prints and updates it.

At a glance

Most sources set an ATH from the highest price ever traded, not from a closing price, so a brief spike is enough to print one. It then stays put until a higher price arrives; every fall in between leaves it untouched. How far today's price sits below it is read as a drawdown, and the ATL, the all-time low, marks the other end of the same range.

Why it comes up often

Traders often use "drawdown from the ATH" to sense where a price sits — for example, "down 40% from its ATH" [2]. Its opposite is the ATL (all-time low). These are just reference points; they do not predict future direction.

What to compare	ATH (all-time high)	ATL (all-time low)	52-week high
What it records	The highest price ever traded	The lowest price ever reached	The highest price of the past year
Period it covers	The whole trading history	The whole trading history	The past twelve months only
How it is read	"Down 40% from its ATH" places today's price	The other end of the same range	A fresh one can print while price sits far below the ATH

All-time high, all-time low and the 52-week high compared on what each records, the period each covers, and how traders read it.

The bottom line

ATH is a cryptocurrency's highest price in its history, a simple reference for where a price sits. It helps build context, but should not be your sole basis for a decision. To keep learning the fundamentals, follow more from Bitbase Academy.

Frequently asked questions

What does ATH mean?

ATH stands for all-time high: the highest price an asset has ever traded at across its whole history. The figure only changes when a higher price prints, so it stays where it is through every fall in between.

How do you check a cryptocurrency's ATH?

Market-data sites and exchanges publish an all-time high on each asset's page, usually next to the date it was set and the current distance from it. The value can differ slightly between sources, because each one reads a different market and trading pair.

Is ATH based on the closing price?

Most sources use the highest traded price rather than a closing price, so a brief spike is enough to set a new ATH. A few publish a close-based figure instead, which is one reason two sites can show different all-time highs for the same asset.

How does an ATH differ from a 52-week high?

An ATH covers an asset's entire trading history, while a 52-week high covers only the past year. An asset can print a fresh 52-week high and still sit far below its all-time high.
