Bitcoin network hash rate declined about 8% over the past week to roughly 920 EH/s, likely driven by higher energy costs tied to the Iran war and rising oil prices. The drop is set to trigger an approximate 8%–10% negative difficulty adjustment — one of the largest recent decreases — and may indicate miner capitulation. Miner margins are being squeezed by rising costs, low fees and price volatility; some public miners are diversifying into AI/HPC and selling more bitcoin to fund operations while BTC trades below $72,000.

Hash rate fell ~8% to ~920 EH/s and is expected to prompt an ~8%–10% downward difficulty adjustment; the summary links the decline to higher energy costs from the Iran war and rising oil prices and notes miner capitulation historically accompanies downside pressure while bitcoin trades below $72,000. Additionally, miners selling more BTC to fund operations and diversifying into AI/HPC are factual signals of squeezed margins.
