Bitcoin miners shut off rigs as new hardware fails to break even
Hash revenue for large public Bitcoin miners has fallen from roughly $55/PH/day in Q3 to about $35–$38/PH/day today, while median all‑in costs are near $44/PH/day. Network hashrate sits around 1.0–1.1 ZH/s, keeping competition and difficulty high. After the 2024 halving (block subsidy cut from 6.25 to 3.125 BTC), ROI for even modern Antminer S21 and Whatsminer M60 class rigs stretches beyond 1,000 days — longer than the ~850 days until the next halving — meaning many new machines will not recoup purchase costs before reward cuts. Traders should note two practical tests miners use: a cash‑flow test (daily revenue vs. operating costs) and a payback test (days to recover capex). At current hash prices and mid‑range industrial power rates, many operators mine at a loss. Options for struggling miners include throttling or curtailing rigs, moving to cheaper power or behind‑the‑meter energy, repurposing sites for AI/HPC workloads, consolidating or exiting by selling hardware. Historically, mass shutdowns lower difficulty and restore margins for survivors, but large public miners with low power contracts can slow that adjustment. Key takeaways for traders: rising miner shutdowns can reduce selling pressure over time as inefficient hashpower exits, but short‑term volatility could increase. Critical thresholds: all‑in power ≲ $0.06/kWh and sub‑20 J/TH efficiency are increasingly required for sustainable mining in 2025.
Bearish
Lower hash revenue (≈$35–$38/PH/day) versus median all‑in costs (~$44/PH/day) means many miners are operating at a loss and are shutting down rigs. In the short term this raises selling pressure as distressed operators may liquidate holdings or hardware, increasing volatility and bearish sentiment. However, historically similar miner capitulations lead to difficulty drops that restore margins for remaining miners, which can reduce future sell pressure and be neutral-to-bullish over the medium term. The current environment is more bearish because large miners with low power contracts can stay online longer, delaying difficulty relief and prolonging margin compression. For traders: expect near‑term downside risk and heightened volatility, but potential supply tightening over months if inefficient hashpower exits.
