Bitcoin miners sell 28,000 BTC as costs bite and difficulty drops

| cryptobriefing.com
Bitcoin miners are accelerating BTC sales as mining economics worsen after the 2024 halving. In 2026, publicly traded miners have offloaded about 28,000 BTC (around $1.78–$2.0B at current prices). Their combined BTC reserves have fallen from roughly 127,000 BTC to about 99,000 BTC, a ~22% drawdown. Mining remains a drag: average publicly traded mining costs are estimated near $74,300 per BTC, while Bitcoin is down ~27% year-to-date in 2026. About 20% of Bitcoin miners are reportedly operating at a loss. The article cites sell-offs by MARA Holdings, CleanSpark, Riot Platforms, Cango, Core Scientific, and Bitdeer. On-chain/network conditions are turning softer too. Mining difficulty has dropped about 18% since the Nov 2025 peak—the longest sustained decline on record—pointing to weaker operators shutting down. However, BTC miner liquidation may be less market-threatening than other flows: miner-related proceeds of about $1.78B are still below current-year ETF net outflows (over $4.4B). Strategy is shifting. Bitcoin miners are increasingly using BTC sales to fund AI and high-performance computing data center operations, where cheap power and dedicated facilities may be more predictable than mining at a loss.
Neutral
Bitcoin miners selling ~28,000 BTC and drawing down reserves (~22%) is a clear near-term bearish signal for BTC supply tightness, especially because ~20% of miners are reportedly loss-making and difficulty is falling (~18% since the Nov 2025 peak). This combination can increase the odds of continued discretionary selling. But the later article also suggests the sell pressure may be partially offset by cross-market flows: miner liquidation proceeds (~$1.78B) are still smaller than BTC ETF net outflows (>$4.4B). That means the marginal impact from miners alone could be limited. Strategically, the pivot toward AI/high-performance compute data centers could reduce the likelihood of immediate structural miner expansion, yet it doesn’t directly change Bitcoin’s protocol security in the short run because difficulty adjustments can stabilize operations. Net impact on BTC price is therefore likely mixed—bearish for sentiment via miner stress, but not overwhelmingly so given ETF-driven flows and difficulty adjustment dynamics.
