Market Performance & Profitability (June 2025 Update)
Profitability Table (Based on $0.06/kWh Electricity Cost)
| Model | Daily Revenue (BTC) | Monthly Profit (USD) | ROI (Months) | Break-even BTC Price |
|---|---|---|---|---|
| Antminer S21 XP Hyd | 0.00042 BTC ($28.50) | ~$855 | 15-18 | $35,000+ |
| Antminer S19 XP | 0.00028 BTC ($18.50) | ~$555 | 18-20 | $38,000+ |
| 螞蟻礦機 L9 | 0.0035 LTC ($0.35) | ~$105 | 24-30 | $85+ (LTC) |

⚠ Market Considerations:
- Post-Bitcoin Halving (April 2024) impact: Block rewards halved, increasing mining difficulty.
- Electricity costs matter: Mining at $0.10/kWh+ drastically reduces profits.
- Altcoins like KDA and LTC can be more profitable for certain miners.
