Bitcoin Dip-Buying Surges Under $77,100; Spot Demand Lags

Market snapshot: BTC slips below $77,100 as dip-buying returns

Bitcoin slid 3.2% to a $75,702 close after breaking beneath the $77,100 range floor, prompting renewed buying in perpetual futures even as spot-market appetite in the U.S. remained muted. The move marks the third close below $77,100 in six sessions and leaves Bitcoin vulnerable to a retest of lower cost-basis levels around $73,500.

Perpetual futures markets showed resilience: open interest dipped during the sell-off then recovered to roughly $52.15 billion, a level slightly above the exposure seen prior to the breakdown. Funding rates stayed positive but not extreme, encouraging traders to incrementally rebuild long positions despite the price decline.

This combination—rising futures exposure, positive funding and increased buy-side taker activity—reflects a dip-buying pattern concentrated in derivatives markets rather than broad-based spot demand.

Key metrics

- Close: $75,702 (down 3.2%) - Recent range: $77,100–$81,300 (previous multi-week trading band) - Futures open interest: recovered to ~$52.15 billion - U.S. spot ETF flows (daily net): -$450.4 million - Notable liquidations on Sep. 15: ~$571 million in longs vs. ~$100 million in shorts

Futures: traders rebuild longs while open interest recovers

Derivatives desks initially pared exposure as BTC fell, but traders were quick to return. Global Bitcoin futures open interest dropped by around $1.7 billion during a sharp intraday decline on Sep. 15, then climbed back to about $52.15 billion by morning trade. That rebuild is distinct from capitulation events, when liquidations and negative funding typically drive a pronounced contraction in open interest.

Funding rates remaining positive—without spiking into overheated territory—made it feasible for traders to add long exposure on margin. Aggregated cumulative volume delta, a measure of aggressive buyer versus seller taker activity, showed a discernible uptick in buy-side taker flow once BTC broke beneath $77,100. In short: perpetual traders were buying the dip even as spot markets showed limited urgency.

The flare of forced selling still removed leverage: roughly $571 million in long positions were liquidated across crypto assets on Sep. 15, with Bitcoin and Ethereum each representing about $190 million of that total. That marked the largest long-liquidation event since Aug. 22 and echoed an earlier liquidation run on Sep. 10 when total liquidations reached about $562 million.

Spot market dynamics: U.S. demand softens

Despite derivative-market interest, spot flows told a different story. Coinbase’s spot price displayed a widening discount versus some other venues—moving from around 0.03% to roughly 0.08% at the Sep. 16 open—flagging weaker buying pressure on the U.S. exchange. That discount was the deepest since mid-August, when Bitcoin briefly traded under $65,000 before the subsequent rally.

U.S. spot Bitcoin ETFs recorded approximately $450.4 million in net outflows on Tuesday, with Fidelity’s FBTC losing about $214.8 million and BlackRock’s IBIT seeing roughly $161.7 million in redemptions. Those two funds made up about 84% of the day’s ETF withdrawals. The outflow was among the larger single-day moves since the ETFs launched in early 2024 and ranked as one of the more significant daily redemptions of 2026.

Earlier in September, institutional ETF flows had been a supportive force—funds gathered nearly $986.7 million in net inflows during the week ending Sep. 4—so Tuesday’s selling reversed a portion of that institutional support and added downward pressure to spot liquidity.

ETF flows vs. options as institutional signals

Bitfinex and market analysts note that ETF flows now offer a clearer lens into institutional positioning than the options market. When ETF inflows falter, it can reduce a structural bid beneath spot prices, making it harder for BTC to reclaim broken range support levels without fresh demand.

Short-term holders and exchange deposits: recent buyers selling into the dip

Exchange inflows from coins held for less than 155 days surged as BTC traded under its range. These short-term holder deposits climbed from about 19,400 BTC to around 33,100 BTC on Tuesday, with roughly 23,200 BTC arriving at exchanges at a loss—the highest such figure in a month.

Loss-making deposits from that cohort to major offshore spot venues totaled approximately 8,260 BTC, the largest since mid-August. By contrast, deposits earmarked for U.S. institutional products—including ETFs and other investment wrappers—remained near their typical level of about 7,300 BTC.

The data suggest recent buyers, often retail-sized positions, accounted for much of the exchange supply. That group had accumulated an estimated 1.23 million BTC between $77,100 and $81,300 over the prior four weeks; with prices now below that range, a meaningful chunk of those holdings sits underwater, increasing the likelihood of exchange sales if prices remain pressured.

Support, resistance and cost-basis levels to watch

Bitfinex’s analysis highlights a nearby support band between approximately $74,985 and $75,412. This zone factors in Tuesday’s intraday low, an identified average purchase price for institutional Strategy holdings, and a prior liquidation cluster near $75,000–$76,000. Strategy’s position size—reported at 845,050 BTC with an average cost around $75,412—places added emphasis on that range.

If that first support band fails, analysts say BTC could test the $73,500 level, which corresponds to the average cost basis of holders who purchased three to six months earlier. A break under $73,500 would expose another near-term marker at roughly $71,300—the realized price for short-term holders—and bring into focus a heavier volume node near $70,000–$71,500 that concentrates about 350,000 BTC of cost basis.

Below those zones, a reversion into the Q1 range of $62,500–$71,000 would be more consequential, potentially signaling a return to a broader bear market regime rather than a transient correction within the recent August-to-September structure.

Options, correlations and macro context

Options activity reflected growing demand for downside protection following the Fed decision. Open interest for the Sep. 18 expiry rose about 22% across that week, with calls up approximately 30% and puts rising near 12%. Longer-dated 25-delta risk reversals shifted toward puts across September, October and December expiries—another sign that traders sought hedges after the volatility spike.

Correlation metrics also moved: Bitcoin’s 10-day correlation with the S&P 500 climbed to about 0.76 from 0.20 on Sep. 11, and correlation with the Nasdaq 100 increased to roughly 0.66 from 0.15. Over the same window, BTC’s correlation with gold decreased from 0.79 to 0.51. Those shifts suggest Bitcoin’s intraday behavior was more tethered to risk assets and equity-market dynamics in the recent stretch.

Macro drivers mattered too. From Sep. 8 to Sep. 15, Bitcoin dropped roughly 3.7% as the 10-year Treasury yield rose from 4.8% to 5%. The inflation-adjusted 10-year real yield closed near 2.62%, boosting the opportunity cost of holding non-yielding assets like BTC.

What traders should watch next

• ETF flows: Continued redemptions would weigh on spot liquidity; renewed inflows could help re-establish a floor above $77,100.
• Futures open interest and funding: A sustained rebuild in open interest with positive funding supports leveraged dip-buying but raises the risk of future liquidation cascades if sentiment reverses.
• Exchange inflows from short-term holders: Elevated deposits indicate distribution pressure; a drop in loss-making inflows would be constructive.
• Critical price levels: $75,000–$75,412 (near-term support), $73,500 (three- to six-month holder cost basis), and $71,300 (short-term realized price).

Risk considerations

Market participants should acknowledge the asymmetric risks when derivative buying masks weak spot demand. Perpetual futures can prop prices via leverage and funding-driven activity, but without supportive spot flows—especially from institutional ETFs—a retracement can be sharper when leveraged positions are unwound.

Importantly, the prevailing mix of positive funding, rising open interest and concentrated liquidation clusters means price action can remain choppy. Traders and portfolio managers should size positions with attention to liquidation zones and hedging costs in both the options and futures markets.

Conclusion: derivatives-led dip-buying amid fragile spot support

Recent price action shows classic derivatives-led buying: traders are using perpetual futures to accumulate longs as funding remains positive and open interest rebounds. But the spot market in the U.S. has shown less conviction, with ETF redemptions and a widening Coinbase discount signaling a shortage of urgent spot buyers below $77,100.

If ETFs stabilize and spot volume picks up, Bitfinex’s downside scenario would be weakened. Conversely, a continued exodus from ETFs combined with sustained exchange inflows from short-term holders could push BTC toward the $73,500 and $71,300 levels identified as key cost bases. For now, derivatives markets are absorbing the decline, but the underlying spot narrative remains the decisive factor for whether this remains a controlled dip or a deeper trend change.
