What Is ATL (All-Time Low)?
ATL (all-time low) is the lowest price a cryptocurrency has reached since it started trading. It is the opposite of ATH and helps show an asset's full historical price range.

ATL stands for “all-time low”, the lowest price a cryptocurrency has reached since it began trading. Its opposite is ATH, the all-time high. On price pages, ATL gives a quick sense of an asset’s full historical range and how far it has travelled from its worst point.
How is ATL calculated?
Data providers combine trade prices from the exchanges they track into a single price series and report the lowest point in that series as the ATL. That means the figure depends on three things: when the data starts, which exchanges are included and which currency the price is quoted in.
Bitcoin’s earliest years, for instance, saw trading on only a handful of thin markets, so different sources can show different ATLs for that period. New tokens raise a similar issue: extreme prints in the first minutes after listing, when liquidity is minimal, can set an ATL far below any price that saw meaningful trading.
How to read distance from ATL
Price pages often show the “change since ATL”. If a token’s ATL was $0.10 and it now trades at $0.50, it is up 400% from the bottom. That tells you how far the asset has recovered from its lowest point.
Watch out for a common math trap. An asset that falls from $10 to $1 has lost 90%, but it needs to rise 900% to get back to $10. After a deep drawdown, a 50% bounce still leaves the price a long way from its old level.
Does a price near ATL mean it’s cheap?
No. Trading near the all-time low doesn’t prove an asset is undervalued. Usage may have dropped, supply may have grown or the team may have stopped building. Assets can set new ATLs again and again, and many tokens eventually get delisted altogether.
Market cap and FDV are more useful than unit price. If circulating supply has doubled, the same unit price represents twice the market value. The project’s tokenomics will show how supply has been changing.
Why does ATL differ by currency?
An asset’s all-time low can fall on different dates depending on the currency used. Bitcoin priced in Turkish lira, euros or dollars traces three different charts, because exchange rates move too. In a currency that has weakened against the dollar, an asset can print new highs on the local chart while still sitting well below its dollar peak.
When comparing figures, keep the currency fixed and note the data source. If you want to check the conversion yourself, our Bitcoin price in USD page shows how the numbers line up. Claims of “the cheapest it has ever been” mean little without a source and a date.
Frequently asked questions
What’s the difference between ATL and ATH?
ATL is the lowest price an asset has ever traded at, and ATH is the highest. Together they frame its historical price range.
Why do sites show different ATL figures?
Each data provider uses different exchanges, start dates and filters for erroneous trades, so small discrepancies are normal.
