2. Choose the Right Mining Pool
| Pool Criteria | Recommendation |
|---|---|
| Fee Structure | ≤2% pool fees |
| Payout Frequency | Daily or hourly |
| Reputation | Low orphan/stale blocks |
Popular pools like F2Pool or Antpool offer reliable payouts. Avoid pools with hidden fees or inconsistent performance.
3. Maintain Hardware for Peak Performance
- Clean dust from fans and vents monthly to prevent overheating.
- Monitor temperatures (ideal: 25–35°C) to avoid thermal throttling.
- Update firmware regularly to leverage performance improvements.
