Bitcoin mining profitability crisis: hashprice collapse, difficulty drops and miner BTC selloff
CoinShares’ Q1 2026 mining report warns that Bitcoin mining profitability is deteriorating fast. Weaker BTC price, collapsing hashprice, and network pressure are pushing more operators to break-even or losses.
In Q4 2025, BTC fell about 31% (from ~124,500 to ~86,000). CoinShares estimates public miners’ weighted cash cost rose to ~$79,995 per BTC. Hashprice then slid from ~$36–38 in Q4 to about ~$29 in Q1, with further downside risk flagged.
A major new signal is three consecutive Bitcoin difficulty reductions (the first streak since July 2022), interpreted as miner capitulation and system-wide profitability shrinkage. At ~$30/PH/s/day hashprice, miners using sub-S19 XP rigs with power costs at or above 6 cents/kWh are likely losing money. CoinShares estimates this could involve ~15%–20% of the global mining fleet.
The stress is showing in treasury actions: public miners cut 15,000+ BTC from peak levels, including Core Scientific selling ~1,900 BTC in January and planning large Q1 2026 liquidation, Bitdeer moving treasury to zero in February, and Riot selling ~1,818 BTC in December 2025.
CoinShares also notes a sector split: some miners stay on pure mining, while others use AI/HPC data-center contracts as a bridge. However, higher leverage around AI builds changes the risk profile.
For traders, this is a bearish backdrop for BTC flows: continued mining losses can increase sell pressure and potentially influence hash rate dynamics and near-term volatility, especially if BTC stays below key levels (e.g., $80,000).
Bearish
CoinShares’ data points to a worsening Bitcoin mining profitability squeeze (hashprice compression, rising stress from BTC weakness and difficulty). The newly highlighted three consecutive difficulty reductions suggests miner capitulation rather than a temporary dip, which increases the likelihood of further BTC treasury sell pressure.
Short term, this can translate into heavier miner-originated selling and potentially higher BTC volatility, especially if BTC remains under key psychological levels (notably $80,000) where the report expects hashprice to keep sliding. Longer term, if weaker miners exit, the sector could later support a more stable return profile, but that stabilization is not immediate and can still come with operational disruptions.
Overall, the direct impact on BTC is more likely negative via sell flows and confidence, making the setup bearish rather than neutral.
