Bitcoin Price Falls 20% Below $87,000 Mining Cost as Hashrate Drops and Difficulty Cut Nears February 8
On February 5, Bitcoin's price slipped to around $70,000, roughly 20% below an estimated $87,000 all-in production cost per coin, while network hashrate fell 12% from its October peak and miner profitability hit a 14‑month low. Daily mining revenue dropped to $28 million, the Miner Profit and Loss Sustainability Index slid to 21, and a roughly 14% downward difficulty adjustment is projected for February 8 as some operators redirect capacity to AI and spot ETF flows turn net negative in early 2026.
