Bitcoin’s seven-day average hashrate fell to 915.8 EH/s, or 915,844,520 TH/s, on September 26, its lowest level since around September 3. Miner reserves tracked by CryptoQuant declined by 1,530 BTC over the week to 1,192,766 BTC. The Puell Multiple rose 0.24 to 1.13, indicating daily miner issuance revenue was above its 365-day average, although the metric excludes electricity, financing and equipment costs. Late-September readings frequently remained below 1 zettahash, while listed miners continued adopting different treasury and infrastructure strategies, including Bitcoin sales and reallocating computing capacity to artificial intelligence workloads. The short-term hashrate decline does not establish that all miners reduced capacity, and Bitcoin continued producing blocks normally.
