Bitcoin mining hash rate and profitability after 2024 halving update

Answer

Bitcoin's network hash rate has declined ~15% from its late-2025 peak of 1,160 EH/s to approximately 970 EH/s as of April 7, 2026—the first post-halving quarterly drop in six years—driven by unprofitable miners shutting rigs amid hashprice lows of $29-31/PH/s/day.[1][2][3] Profitability remains viable only for efficient operators (<20 J/TH efficiency, <$0.05/kWh power), with public miners' all-in costs averaging $118k-$170k/BTC at current $69k BTC prices; 15-20% of the fleet is underwater, accelerating AI pivots.[4][1]

Key Context

• Hash Rate Trends: Post-April 2024 halving (~600 EH/s), network grew 90%+ through 2025 via new ASICs (S21/XP), peaking at 1,160 EH/s (Oct 2025); Q1 2026 saw -10% drop to ~850 EH/s low (Feb, weather/curtailments in Texas/Xinjiang), partial recovery to ~1,020 EH/s by March, now 970 EH/s (7D SMA ~939 EH/s).[1][5]
• Profitability Metrics: Hashprice crashed to $29/PH/s/day (March 2026 low, 5-year trough), yielding ~$0.032/TH/s/day at $68.8k BTC; breakeven electricity now ~$0.077/kWh for S19 XP (down from $0.12 pre-2025), squeezing mid-tier rigs (S19j Pro unprofitable at $0.05/kWh).[5][6][1]
• Geographic/Operator Distribution: US leads at 37.5% (~365 EH/s), followed by Russia (16.4%, ~160 EH/s) and China (21%, ~200 EH/s); top 3 control 68%; public miners hold 413 EH/s (42% of network, Mar 31), led by MARA (53 EH/s), CLSK (50 EH/s), IREN (46 EH/s).[7][8][1]

• Capitulation Signals: Three negative difficulty adjustments in Q1 2026 (latest -7.76%, difficulty now 139T); miners sold >15k BTC (e.g., Core Scientific 1,900 BTC); 20% unprofitable per CoinShares, echoing 2021 cycle bottoms.[9][1]
• AI Pivot Momentum: Miners inked $70B+ AI/HPC deals (e.g., CoreWeave-CORZ $10.2B/590MW); AI now 30% of revenues for some (CORZ 39%), projected 70% by end-2026, diverting ~10% hash rate.[1]

"Hash price fell to ~$36–38/PH/s/day in Q4 2025, further to ~$29/PH/s/day in Q1 2026 (all-time post-halving low)." – CoinShares Q1 2026 Report[1]

What to Watch

• BTC Price Recovery: Needs ~$100k for hashprice >$40/PH/s/day and 1.8 ZH/s end-2026 forecast; sub-$80k risks further flatline/decline.[1]
• AI Cannibalization: $70B+ contracts could shift 10-20% hash rate; track hybrid models (e.g., MARA's 10MW flexible sites) and revenue mix (mining vs. AI/HPC).
• Hardware/Consolidation: Sub-10 J/TH ASICs (Bitmain S23, SEALMINER A3) H1 2026; expect M&A among high-debt firms (IREN $3.7B notes) if capitulation persists.

Source Freshness

Primarily real-time April 7, 2026 data from Hashrate Index, CoinWarz, BitInfoCharts (high-quality on-chain aggregators); CoinShares Q1 report (March 25, 2026, comprehensive but slightly dated); X posts from March-April 2026 (e.g., @CryptoPatel, @TFTC21) for sentiment—treat pre-April as potentially stale amid volatility.[4][9]
