Bitcoin is facing two simultaneous storylines: a long-term security-budget debate over how transaction fees arrive block by block, and a short-term rally supported by more than $2 billion in spot ETF inflows. A July 2026 NBER working paper by Fabian Schär, Dario Thürkauf, and David Yermack found that larger fee differences between adjacent Bitcoin blocks are associated with more competing blocks at the same height and a longer wait for the next block, using data from 2017 through 2025.
Bitcoin miners currently receive a fixed subsidy of 3.125 BTC plus transaction fees. Glassnode data on Aug. 26 put transaction fees at about 0.70% of miner revenue, while a BTC.network weekly report had 0.67%. Still, block-level data can vary sharply: one Aug. 26 snapshot showed 0.0077 BTC in fees in block 964,120 and 0.0536 BTC in block 964,121, almost a seven-fold difference. The researchers say such gaps can make it more economically attractive for a miner to attempt to rebuild a valuable prior block rather than simply extend the newest tip. They stress the evidence is observational and does not resolve individual miner intent, but it provides a measurable network-level signal.
Anti-fee-sniping protections could reduce the prize unevenly. Bitcoin wallets can set lock fields so transactions become mineable after the current tip, excluding them from a replacement of the current tip. BIP 326 describes anti-fee-sniping behavior for Taproot transactions, but adoption remains inconsistent. An open Bitcoin Core issue from April 2026 notes that some transaction-creation paths default to nLockTime near the current block height while others default to zero.
On the market side, Bitcoin hit an intraday high of $79,251.60 on Aug. 26 and traded near $78,000 as of press time. July's PCE inflation held at 3.7% headline and 3.3% core, leaving the policy debate largely intact. Futures markets raised the odds of a September rate hike to about 44%, up from 36% before the report. Bitget Research chief analyst Ryan Lee said the in-line core print 'settles little' and expects Bitcoin's direction to come from ETF flows, spot liquidity, and derivatives positioning.
Glassnode reported that US-traded spot Bitcoin ETFs absorbed $2.23 billion around the initial squeeze, with the strongest seven-day intake of 2026 and no single outflow day. Farside Investors showed another $314.3 million in inflows on Aug. 25, led by $284.4 million into BlackRock's IBIT. The positive streak from Aug. 17 through Aug. 25 totaled roughly $2.6 billion. At the same time, every wallet-size cohort accumulated, and Aug. 19 produced the largest dollar-denominated single-day short liquidation event in Glassnode's dataset since 2019, with about 85% of liquidations coming from shorts.
Glassnode also noted that Bitcoin futures open interest fell 11% in BTC terms during the late-August squeeze, while perpetual funding stayed mostly positive but near neutral. This suggests the move was not simply fresh speculative leverage rebuilding. Sygnum Bank CIO Fabian Dory described the macro backdrop as 'gradual disinflation rather than a demand shock.' Total stablecoin market capitalization sits near $303.7 billion, up $2.8 billion over the past week, and NYDIG data shows stablecoin supply rose $1.25 billion during the rally, mostly from USDC.
Looking ahead, roughly 81,700 Bitcoin options worth $6.44 billion expire on Deribit Friday at 08:00 UTC. Key levels include the $81,000 to $86,000 resistance zone, a dealer gamma flip near $82,300, and Glassnode's breakout confirmation level at a settled close above $83,300. Bullish scenarios target $95,000 to $100,000 if ETF demand persists, while the short-term-holder cost basis near $70,000 and the $62,000 to $65,000 floor mark downside support.
