Bitcoin Miners Reach 'Surrender Phase': Production Cost Inversion, Both Hash Rate and Stock Price Under Pressure

**Bitcoin Mining Enters Crisis Phase as Hashrate Revenue Plummets to Historic Low** On February 11, the Bitcoin mining industry slid into a critical downturn, with per-unit hashrate revenue hitting an all-time low of roughly $35 per PH/s. A sharp market correction has dragged Bitcoin’s price down over 50% from its October 2025 peak of $126,000, now hovering around $60,000. In this landscape, **the network-wide average cost to mine one full Bitcoin stands at ~$87,000—about 45% higher than current market prices**—marking the first widespread "underwater mining" (costs exceeding revenue) since the 2022 bear market. CryptoQuant has labeled the current phase a "surrender period," defined by accelerated shutdowns of outdated mining rigs and a sharp contraction in network hashrate. As a result, public mining firms like MARA Holdings and Riot Platforms have seen their stocks drop more than 20% this week, with capital shifting to stable traditional assets like gold. Meanwhile, North American mining hubs (notably Texas) are reeling from a severe cold snap, forcing some facilities to curtail power use to safeguard civilian grid stability. Combined with miners exiting the market, the Bitcoin network saw a historic 11% difficulty adjustment on February 9. However, the profitability boost from this adjustment has been muted due to the steep price drop. The industry’s *Miner Breakeven Sustainability Index* has fallen to 21, meaning only a handful of operators with ultra-low electricity costs and high-efficiency rigs are avoiding margin compression. For firms paying over $0.05 per kWh or relying on obsolete equipment, the difficulty adjustment won’t reverse the risk of full shutdown. To weather the "2026 Mining Winter," top players are accelerating shifts to Artificial Intelligence (AI) and High-Performance Computing (HPC). Companies like IREN and Core Scientific have reallocated some data center power capacity to AI businesses to lock in stable long-term contracts. Bitfarms recently announced it will exit Bitcoin mining entirely to focus on an AI-centric strategy.
