================================================================================
VERDICT: Excellent for research/prototyping, inadequate for production
================================================================================

KEY TAKEAWAYS:

✅ Strengths:
   • Full historical access (genesis to present)
   • No authentication required
   • Batch request support
   • Complete data (no gaps)
   • Free to use

❌ Limitations:
   • Very strict rate limits
   • No way to increase limits
   • Slow for large backfills (~18 hours per 1M blocks)
   • Not suitable for production

💡 Recommendation for gapless-network-data:
   Use LlamaRPC for testing/prototyping only.
   For production, use Alchemy/Infura with API keys or run local Ethereum node.
