Bitcoin liquidation heatmap

What the map shows

A perpetual futures position is borrowed money. Every leveraged trade carries a price at which the exchange closes it automatically, because the margin behind it has run out. That price is not a secret: it follows mechanically from the entry price and the leverage used.

This map is the liquidation heatmap for the selected venue's BTC perpetual over the chosen window. It takes the open interest added in each period, works out roughly where those positions were opened, and projects the price at which each standard leverage tier would be liquidated. Stack all of those projections together and you get a surface: bright where a lot of forced closing sits waiting, dark where there is almost none.

Bitcoin is the reference case for this kind of map. Its perpetual is the most traded derivatives contract in crypto, the picker reaches every book that carries a meaningful share of it, and the longer windows exist here that do not exist for smaller assets. If you learn to read one heatmap, learn to read this one first.

Time runs left to right, price runs bottom to top: The dotted line is the actual BTC price over the same window. Bands that survive to the right edge are leverage that price has not yet reached.

How to read it

• Bright bands above price are shorts. If BTC rallies into one, those shorts get bought back by the exchange, which adds buying to a move that is already up.
• Bright bands below price are longs. If BTC falls into one, those longs get sold, which adds selling to a move that is already down.
• A band that ends abruptly was consumed. Price traded through it, the positions were closed, and the liquidity is gone. That is why the surface is cleared behind the price line rather than left painted.
• Thin, tight bands very close to spot are the 100x crowd. They are large in count and small in notional, and they get taken out constantly.
• Wide bands far from spot are the 10x crowd. Rarer, much bigger, and the ones that produce the headline cascades.

What is different about Bitcoin leverage

BTC perpetuals are the deepest leveraged market in the asset class. Binance's USD-M BTCUSDT contract alone routinely carries more open interest than every altcoin perpetual combined, and Bybit, OKX and Hyperliquid each run books that would be the largest market on most other pages of this site. Depth cuts both ways: it takes a bigger cluster to move Bitcoin than to move anything else, and when one does fire the book absorbing it is the thickest in crypto.

The reason a BTC cluster matters beyond BTC is correlation. Almost every altcoin trades as a higher-beta version of Bitcoin, so a cascade that starts on the BTC book does not stay there. It reprices every alt at once, reaches the leverage sitting on those books, and the alt cascades feed back into sentiment on Bitcoin. Traders who only hold altcoins still watch this page, because the first domino is usually here.

Two large pools of Bitcoin leverage are not on this surface. Coin-margined (inverse) perpetuals, where the collateral is BTC itself rather than a stablecoin, run separate books with their own liquidation prices, and the CME's cash-settled futures are not perpetuals at all. Both matter to the total picture, and both are outside what any USDT-margined heatmap can show. Treat the map as the largest slice of BTC leverage, not the whole of it.

Bitcoin and Ethereum are the two assets with 180 day and one year windows. On BTC those long windows are worth the click: the wide, low-leverage bands that have survived months untouched are where the largest single liquidation events in the asset's history have been triggered, and they are invisible on a 24 hour view.

Why clusters move price

A liquidation is not a normal sale. It is a market order the exchange sends on the trader's behalf, at whatever price the book offers, with no regard for slippage. When a dense cluster is hit, thousands of those orders fire inside a few seconds against a book that has usually already thinned out.

That is the cascade mechanic. Price reaches a cluster, the cluster fires, the firing pushes price further in the same direction, and the push reaches the next cluster. It stops when it runs out of stacked leverage or when resting bids and offers are deep enough to absorb the flow.

Using it without getting run over

1. Watch it even if you are not trading BTC: A Bitcoin cascade reaches altcoin books within seconds through correlation. Dense BTC leverage is a risk to any leveraged position on any asset.
2. Treat clusters as risk, not as entries: Knowing where forced selling sits tells you where a move is likely to accelerate. It does not tell you the move is coming.
3. Do not park a stop inside a cluster: That is precisely the price where slippage is worst.
4. Watch which side is heavier: When one side of price holds most of the leverage, the path of least resistance usually runs toward it.
5. Check the window: A cluster built over thirty days is a different animal from one built in the last six hours.
6. Size for the cascade, not the level: If you are long into dense long liquidity below, assume the fall through it will be faster than normal.

What it cannot tell you

• A blended level is not one order book: All exchanges adds the venues together, so a bright band there can be mostly one book. Only that book's own price trading through it triggers those positions, so pick the venue out before sizing around a level.
• It cannot see cross-margin: A trader with collateral spread across several positions is liquidated on portfolio health, not on a single price.
• It assumes standard leverage tiers: Real traders use 7x and 33x and every number in between.
• It is not a forecast: A dense cluster at 8% below spot says what happens if price gets there. It says nothing about whether it will.
