An all-time high, usually shortened to ATH, is the highest price an asset has ever traded at since it began trading. Nothing about it acts as a ceiling. It holds until something breaks it.
On 6 October 2025, Bitcoin set its most recent record at $126,296. In crypto the term carries unusual weight, because a large share of holders bought during a previous cycle and are waiting for an old high to return.
How an ATH is measured
Sounds like an objective number. It is not, and the differences trip people up.
- Which venue. Prices differ across exchanges. On one thin market, a wick can print higher than anywhere else traded.
- Which currency. An asset can hit a high in dollars while sitting well below its high against Bitcoin.
- Wick or close. Some sources record the highest price touched inside a candle, others only the highest closing price. Intraday spikes can differ from the closing high by a noticeable margin.
- Aggregated or single-source. CoinMarketCap and CoinGecko publish volume-weighted averages across many exchanges, which usually sit slightly below the single highest print anywhere.
Two sites can therefore show different ATH figures for the same asset on the same day. Neither is wrong. They measure different things.

| Term | What it means |
|---|---|
| ATH | The highest price ever reached |
| ATL | The lowest price ever reached |
| Drawdown from ATH | How far below the record the price currently sits, as a percentage |
| Price discovery | Trading above the previous record, where no historical price data exists |
| Local high | The highest point within a recent window, not an all-time record |
Why traders watch it
Price discovery. Above the ATH there is no prior trading history, which means no resistance levels drawn from where people previously bought and sold. Technical analysis loses most of its reference points.
Supply overhead disappears. Below an ATH sits a population of holders at a loss, some of whom sell as the price approaches their entry. Above it, in principle, every holder is in profit and that source of selling pressure is gone.
Attention. New records generate coverage, which draws in people who were not watching. That reflexivity is real, and it runs in both directions.
What an ATH does not tell you
- Nothing about what happens next. Records get broken and records hold for years. The number contains no forward information.
- Nothing about value. An ATH is a price, and price is what the marginal buyer paid at one moment.
- Nothing about the asset's health. A token can print an ATH on a thin book and low volume, which says more about liquidity than demand.
- Nothing about your position. The ATH tells you where the asset traded, not what you paid.
The recovery arithmetic
Worth internalising, because it is not symmetric.
Fall 50% from an ATH and the price must double to get back. At a 90% drawdown, the requirement is 900%. At 95%, it is 1,900%.
Hence why "down 80% from the all-time high" understates the return trip. Percentage down and percentage needed to recover are different numbers, and the gap widens sharply as the drawdown deepens.
A historical anchor
For just over three years, Bitcoin's November 2021 peak of roughly $68,789 stood as its record, through a decline that took the price to $15,476 by the end of 2022.
Buying at that peak meant three years underwater on a position in the largest and most liquid asset in the market. Then the record broke. A new one was set at $126,296 in October 2025.
That is the useful lesson from ATH data. Records get made when sentiment is most confident, which is structurally the point at which the fewest people are worried.

Frequently asked questions
What is Bitcoin's all-time high?
$126,296, set on 6 October 2025. Before that, roughly $68,789 in November 2021, a record that stood for just over three years.
Why do different sites show different all-time highs?
They measure differently. Some use a volume-weighted average across exchanges, others the single highest print anywhere. Some count intraday wicks, others only closing prices.
What does price discovery mean?
Trading above the previous all-time high, where no historical price data exists to reference. Technical levels drawn from past trading do not exist above that point.
If an asset is down 80% from its ATH, how much does it need to recover?
400%. Asymmetric arithmetic: a 50% fall needs a 100% gain to recover, a 90% fall needs 900%.
Does a new all-time high mean an asset is overvalued?
About value, the number says nothing. Assets in long uptrends set repeated new highs over years, and plenty print one high and never return to it.
What is the difference between an ATH and a local high?
An ATH is the highest price ever. Within a defined recent window, such as 90 days, a local high is the peak, and it can sit far below the record.
Do altcoins have all-time highs against Bitcoin?
Yes, and they frequently differ from dollar records. An altcoin can reach a dollar ATH while sitting far below its Bitcoin-denominated high, which indicates it gained value and underperformed Bitcoin.
