Glassnode: BTC Rebounds 26% After Short Squeeze, $81,000–$86,000 Becomes Key Supply Resistance Zone

According to Glassnode, Bitcoin has rebounded approximately 26% from its mid-August low, driven primarily by record short liquidations. August 19 marked the largest single-day short liquidation day monitored since 2019, with shorts accounting for 85% of total liquidations within the squeeze window. Over the same period, coin-denominated BTC futures open interest fell by 11%, while perpetual contract funding rates remained largely neutral, indicating that the rally was not accompanied by significant new leveraged long positioning. On the capital flow front, U.S. spot Bitcoin ETFs recorded cumulative net inflows of $2.23 billion during this window, with no single-day net outflows, marking the strongest consecutive seven-day inflow streak of the year. The 30-day accumulation trend scores for wallets across all size categories remained above 0.5, reflecting broad-based buying coverage throughout the market. However, Glassnode notes that the $81,000–$86,000 zone concentrates the cost basis of long-term holders, sell orders, options market maker negative gamma positioning, and potential short liquidation bands, forming the primary resistance to the current rebound. The report suggests that if BTC holds above $83,300 alongside sustained ETF inflows, it may signal that this supply zone is being absorbed. Downside focus should then shift to the $70,000 short-term holder cost basis, followed by the $62,000–$65,000 support range.
