BTC gains close to 3%, open interest increases only mildly: so who’s buying this time?

$BTC is up nearly 3% over the past 24 hours, while open interest has only risen moderately. So who’s buying here—and why hasn’t the derivatives market pushed the rally even hotter?

Fact: On Binance USD-perpetual contracts, $BTC is at $79,764, up 2.91% in 24 hours, with trading volume of about $18.75 billion; $ETH is at $2,490, up 1.32%, with volume of about $14.83 billion. BTC and ETH are both TRADING.

But over the last three hours, the notional value of BTC open positions has only increased by about 0.74%, and ETH by about 0.72%. BTC funding rate is around 0.59 bps, and it hasn’t clearly heated up along with the near-3% intraday gain. Price expansion is happening faster than the growth in new positions—this isn’t the same as “a surge driven by a pile of leverage chasing price.”

Funding reality: According to Farside’s latest data, on August 24, U.S. spot BTC ETF net inflows were $125.4 million, and ETH ETF net inflows were $20.2 million. This suggests spot demand is still present, but it doesn’t prove that every minute of this move is ETF buying—and it can’t rule out short-covering by shorts or short-term spot-driven momentum.

Why can positive factors and price reaction be inconsistent? Because ETFs reflect the allocation results from the previous trading day, while perpetual contracts trade today’s risk appetite. If price rises while open interest increases only modestly, it could mean spot moved first—or that shorts are being forced out.

The market is still confirming: after the rise, can trades continue and pullbacks get absorbed, instead of judging everything from a single bullish candle.

For longs to be “right,” BTC needs to hold steady and keep trading active, with open interest increasing moderately and funding remaining restrained—that would indicate the new risk hasn’t run out of control. For shorts to be “right,” price rises then falls back, with open interest accelerating again while trading volume can’t keep up—that would imply that chasing leverage is taking over. The most common mistake is to treat a low fee rate as if there’s no risk.

My view: I’m more inclined to watch whether, during BTC’s pullback, there’s still spot absorption—then use that to judge whether this rally can continue. A rally without being overcrowded is a good sign, but it’s not a guarantee against a drop. Without volume support, a breakout can quickly turn into two-way liquidations. Risk warning: near round-number support/resistance levels, both liquidity and liquidations can amplify volatility—keep position sizes light and pre-set stop-losses.

Getting the breakout right doesn’t mean you can comfortably hold through the pullback.
