What does ATH mean in crypto?

ATH in crypto means all-time high, the highest price a cryptocurrency has ever traded at. Its opposite is ATL, the all-time low. Both terms come up constantly in crypto news and on price pages, where they show how far a coin now sits from its best and worst moments.

What does ATH mean in crypto?

CoinGecko defines ATH as the highest point a cryptocurrency has reached in its history, measured in price or in market capitalization. Price pages usually show the ATH figure, the date it was set, and how far the current price is above or below it.

When a coin breaks its previous record, news outlets report that it has hit a "new ATH." During long rising periods a coin can set several new highs in a row, which CoinMarketCap's glossary connects to the idea of a bull run. Our guide to bull and bear markets explains those wider cycles.

ATH is a record of the past, not a target. Coinbase notes that reaching an ATH does not mean an asset will stay at that level.

What is the difference between ATH and ATL in crypto?

ATL is the lowest price a coin has reached since it launched. For a new token, the ATL is often in its first days of trading. Coinbase describes trading near an ATL as generally seen as a bearish sign, but adds that a low is never guaranteed to be the final one.

Together, the two figures show a coin's full historical range. Many price pages also show the percentage change from the ATH, sometimes called the drawdown. CoinMarketCap's glossary notes that falls of more than 70% from a peak have been common in crypto bear markets, and that some altcoins have dropped 90% or more. Long stretches like that are described in what a crypto winter is.

What is the ATH of bitcoin?

Bitcoin set its most recent all-time high in early October 2025. Reuters reported a new record on October 5, 2025, and price trackers recorded the peak the following day, October 6. As of early October 2026, a KuCoin news report said bitcoin still traded below that level, one year later. Because records change, check a live data source for the current figure.

Why do ATH figures differ between sites?

Crypto trades on many exchanges at once, and each one has its own prices. Data aggregators combine those prices in their own ways, and a news report written mid-day can capture an earlier figure than the final peak. That is why the Reuters record and later tracker records for bitcoin's 2025 high differ slightly.

Coinbase also points out that an ATH can reflect a quoted price rather than a completed sale, depending on how it was recorded. Thinly traded coins can briefly spike on a single trade, so a dramatic ATH on a small token may say little about where most trading happened. For more trading terms, see the crypto glossary.
