Bticoin Mining the total calculation power securing the network just master a amazing one-day stream, leap from around 660 EH/s to over 1,000 EH/s, a 30%+ increase in under 24 hours. Meanwhile, BTC hovered near $107,000 during the spike.
This recoil marks the strongest single-day hashrate stream in months, indicating a rapid return of mining activity.
What Triggered the Drop & Surge?
Geopolitical Shocks & Miner Curtailment
U.S. Iran tensions prompted safety shutdowns in facilities abroad. Iran, once responsible for ~4% of global hashrate, dropped to near 0.1%, contributing to the sudden dip.
Weather-Related Shutdowns
A hot weather in Texas and lower hydroelectric power generation in Canada and China led to temporary pauses in exercises.
Maintenance & Load Management
Major mining sites went offline briefly for routine maintenance or power testing before swiftly rebooting, triggering the explosive rebound.
Bigger Picture: Hashrate & Profitability Trends
- In May 2025, Bitcoin’s network hashrate alternated between 831 EH/s and 921 EH/s, rising nearly 77% from its April 2024 low of ~519 EH/s.
- As of late June, hashrate lingered around 746–692 EH/s, while its all-time high peaked at 1,124 EH/s on April 13, 2025.
- The current network difficulty stands near 126 T, with miners’ production cost estimated between $90k–$98k per BTC.
Major Public Miners Driving Growth
In May 2025, top publicly traded miners collectively added 17.9 EH/s to their realized hashrate about a 15.5% month-over-month increase :
- MARA (Marathon): Reached 58.1 EH/s, mined 950 BTC, +30% vs April .
- CleanSpark: Produced 694 BTC, with 42.48 EH/s, and projects exceed 50 EH/s in June.
- Riot Platforms: Achieved 32.76 EH/s, +6.6% from April .
- This surge coincided with difficulty hitting new highs, underscoring the industry’s competitive ramp-up .
Efficiency Advances & Energy Trends
- Hardware leapfrogging with ASICs like Bitmain Antminer S21+ (~16.5 J/TH) and MicroBT WhatsMiner M66S+ (~17 J/TH) is boosting output per watt.
- Quirk (daily earnings per TH/s) dropped post-halving from $0.12 to about $0.049, squeezing slim-margin operators.
- As energy costs spike, miners are targeting low-cost zones: Oman ($0.05–0.07/kWh), UAE ($0.035–0.045/kWh), while U.S. miners face >$0.10/kWh.
What This Means for Bitcoin
- Stronger Security: Higher hashrate increases protection against 51% attacks.
- Gain Pressure: Smaller miners face squeeze and likely consolidation unless they improve efficiency.
- Environmental Diversification: Mining is shifting towards low-cost, stable energy regions Africa, Central Asia, the Middle East.
What to Watch Next
- Hashrate Trends: Will the current high 700‑900 EH/s level hold steady, or slide back during summer grid stress?
- Difficulty Adjustments: Anticipate downward tweaks if block times slow restoring breathing room for miners.
- Miner Innovations: Efficiency, co-location with AI/HPC, and renewable energy deals could define winners .
Final Thoughts
The explosive 30% one-day hashrate spike emphasizes Bitcoin mining’s resilience and professional evolution. While network security strengthens, profitability reckons continue driving consolidation and operational upgrades.
