Bitcoin Mining Difficulty Plunges 11% After US Winter Storms: What It Means for Automated and Copy Trading

⛏️ What Happened: The Largest Bitcoin Mining Difficulty Drop Since 2021

Bitcoin mining difficulty fell 11.16% to 125.86 T on February 9, 2026, marking the largest single adjustment since the 2021 Chinese mining ban. This dramatic reset was triggered by a perfect storm: severe US winter weather, a 45% BTC price crash, and widespread miner shutdowns. For traders leveraging automation and copy trading tools, this event is a masterclass in volatility, network risk, and opportunity. ⚡️🤖

🌨️ Why Did Mining Difficulty Plunge?

• Winter Storm Fern: Beginning January 26, the US was hit by extreme cold, freezing mining operations in key regions (PJM Interconnection, TVA). Miners curtailed power use to stabilize the grid, slashing hashrate 20% in a month.

• BTC Price Collapse: Bitcoin fell 45% from October 2025 highs, with spot prices near $60,000—well below the average mining cost of $87,000. Unprofitable miners powered down en masse.

• Profitability Crisis: Hashprice (profit per PH/day) hit record lows near $33, forcing even large operators to liquidate BTC reserves. Public miner Cango sold $305M in Bitcoin to cover costs.

📉 Price Impact & Market Reaction

• BTC hit a 2-year low at $60,000, triggering $689M in ETF outflows and a "risk-off" rotation across crypto and equities.

• Network hashrate plunged to 863 EH/s from a 1.1 ZH/s peak in October 2025.

• U.S. spot Bitcoin ETFs became net sellers for the first time in 2026.

🔍 Expert & Analyst Insights

• Blockspace Media: "This is controlled capitulation, not panic. If BTC stabilizes above $60K, hashrate could rebound by the next adjustment (Feb 20)."

• Unchained Crypto: "Lower difficulty helps survivors, but if price stays low, more shutdowns are likely. Watch for another reset if miners keep exiting."

• AInvest: "ETF outflows and miner sales show institutional caution. Automated strategies should monitor both on-chain and macro signals."

🚦 Actionable Strategies for Automated & Copy Traders
