The mining sector continues to navigate challenges two months after Bitcoin's third halving event. Surging network hash rates and renewed market enthusiasm have propelled Bitcoin (BTC) and Ethereum (ETH) prices upward, leaving miners with mixed fortunes.
The Current State of Bitcoin Mining
- Post-Halving Fallout: The halving triggered a market shakeout, eliminating 15%-30% of small-scale miners while top mining pools remained relatively stable.
- Hash Rate Fluctuations: Bitcoin's hash rate dropped 27% from 135 EH/s to 98 EH/s post-halving, with daily declines averaging 6.5%.
- China's Dominance: Chinese mining pools control 65% of Bitcoin's total hash power, though pandemic-related delays in ASIC deliveries impacted efficiency upgrades.

Pandemic Impacts and Industry Adaptations
Equipment Market Dynamics
- Supply Chain Recovery: Major manufacturers like Bitmain and Canaan resumed operations by Q2 2020, with new models entering the market.
- Enterprise-Level Moves: Mining operator Powerry expanded capacity with $20M in new equipment orders, partnering with Genesis Mining for energy management solutions.
Operational Resilience
- Large-scale Chinese farms maintained operations despite temporary closures
- Hash rate stability preserved through rapid capacity redistribution
- Short-term difficulty adjustments improved mining margins
Ethereum's Pivotal Moment: ETH 2.0
The upcoming transition to Proof-of-Stake presents both challenges and opportunities:
- Miner Migration: Some operations are shifting to ETH/altcoin mining despite higher hardware costs
- Investment Horizons: ETH mining equipment offers faster ROI than Bitcoin ASICs
- Long-Term Viability: POS transition unlikely to completely displace miners due to DeFi's growing transaction fee economy

Altcoin Mining Considerations
| Factor | Bitcoin | Ethereum/Altcoins |
|---|---|---|
| Price Stability | High | Volatile |
| Equipment Cost | $1,500-$3,000 | $3,000-$6,000 |
| ROI Period | 18-24 months | 8-12 months |
| Energy Efficiency | 40-60W/TH | 150-300W/GPU |
Industry Outlook and Future Trends
- Fee Economy Evolution: Transaction fees may surpass block rewards as dominant miner income
- Manufacturer Innovation: Next-gen ASICs targeting improved energy efficiency
- Geographic Diversification: Mining operations expanding beyond China to North America and CIS regions
FAQ: Mining Industry Transition
Q: How long before old mining equipment becomes obsolete?
A: Antminer S9s became unprofitable post-halving, with newer models like S19 Pro offering 3x efficiency.
Q: Will ETH 2.0 eliminate mining entirely?
A: No - Phase 0-2 transitions will take 2-3 years, with mining continuing during the hybrid PoW/PoS period.
Q: Which altcoins are miners migrating to?
A: Dash, Zcash, and Grin currently offer the best ROI for GPU miners transitioning from ETH.
Q: How are mining pools adapting?
A: Leading pools like F2Pool now support multi-algorithm switching based on profitability.
Q: What's the break-even electricity cost for Bitcoin mining?
A: Currently $0.05-$0.07/kWh for modern ASICs at BTC prices above $10,000.
