Crypto-margined Bitcoin futures now account for roughly 12% of open interest across all exchanges, according to Glassnode's long-run metric. That is a long way from where the market sat in 2019 and 2020, when crypto-margined contracts made up close to 100% of open interest. Open interest counts every futures contract opened but not yet settled, so the metric tracks not just how large the leveraged market is, but what its collateral is actually denominated in.

For most of the last decade, opening a BTC futures position almost always meant the margin was denominated in BTC. Bitcoin futures traders have all but abandoned crypto as collateral. A crypto-margined position is collateralized in the asset being traded, so a price drop shrinks the trader's buffer at the exact moment the trade is moving against them—a feedback loop that can trigger a margin call just as the market is moving fastest. Stablecoin-margined positions, by contrast, sit in dollars, so the collateral keeps its value while the trade swings. The market saw that loop run in March 2020, when a two-day crash took Bitcoin down as much as 50% and pushed more than $1 billion in liquidations through BitMEX—then the leading crypto-margined venue—which also suffered a brief outage at the depth of the selloff. In the years since, the largest derivatives exchanges, including Binance, Bybit, and OKX, have built their product lines around stablecoin-margined contracts. Traders have simply chosen the steadier float.

The move toward stablecoins mirrors how the broader derivatives market has matured. Coinbase opened U.K. derivatives trading through Hyperliquid with up to 50x leverage this month, Bitcoin ETFs drew $854 million over five days as rate-hike bets faded, and Strategy trimmed its Bitcoin stack—all signs of institutional flow that tends to settle in dollars, not coins.

None of this cooled spot demand this week. Bitcoin rebounded from around $57,000 to a weekly close near $79,175, up about 1.88% today, after months of low-volatility drift between $60,000 and $68,000. That said, these events are not in a causal relationship.

The 24-hour liquidations are a textbook short squeeze, per CoinGlass data: $570.08 million wiped, with shorts hit harder at $329.60 million versus $240.48 million in longs. The losses snowballed as price climbed, with Bitcoin's $295.41 million slice the largest and a $103.54 million BTC position on Bitget the single biggest blowup.

But that squeeze and the collateral shift are not the same story, even if both show the current state of the crypto market. Stablecoin margin has been the dominant structure for years, and the trend has been moving one way the whole time: dollar collateral steadily displacing crypto as the backing for leveraged bets.

Broader access to fiat markets simply increases the exposure of investors looking for ways to trade crypto, which in turn makes the coin less susceptible to major price movements after disrupting trades.

For the markets, however, leverage is leverage no matter what backs it—dollar margin didn't cause this week's liquidations, and it won't prevent the next ones. Based on this data alone, the Bitcoin squeeze may not be over. Two data points back this up, even if they are independent: one is the slow architecture of the market, the other the noise of its daily movements. Both threads can be followed on the dashboards cited here—Glassnode's long-run chart for the collateral mix, and CoinGlass's liquidation tracker as the tape keeps moving.
