[Glassnode: BTC Rebounds 26% After Short Squeeze, $81,000–$86,000 Becomes Key Supply Resistance Zone] Deep Tide TechFlow reports that on August 27, according to a Glassnode report, Bitcoin has rebounded approximately 26% from its mid-August low, primarily driven by record-breaking short liquidations: August 19 marked the largest single-day short liquidation event since 2019, with shorts accounting for 85% of all liquidations during the squeeze window. During the same period, BTC futures open interest denominated in coins dropped by 11%, and perpetual contract funding rates remained neutral overall, indicating that the rally was not accompanied by significant new leveraged long positions. On the capital side, U.S. spot Bitcoin ETFs saw a cumulative net inflow of $2.23 billion during this window, with no single-day net outflows, marking the strongest seven-day inflow streak of the year. The 30-day accumulation trend scores for wallets of all sizes were above 0.5, reflecting broad market buying activity. However, Glassnode pointed out that the $81,000–$86,000 range, which aggregates the cost basis of long-term holders, sell orders, negative gamma positioning by options market makers, and potential short liquidations, constitutes the main resistance for the current rebound. The report suggests that if BTC can stabilize above $83,300 and maintain ETF inflows, it may indicate that this supply zone is being absorbed. On the downside, attention should be paid to the $70,000 cost basis for short-term holders and the $62,000–$65,000 support range.
