🎯 Key Takeaways

You've learned how cryptocurrency mining works as a competitive race, how difficulty adjustment maintains network stability, and why mining pools dominate the landscape.

🏁

Winner Takes All

Mining is a zero-sum game. First to find valid hash gets 6.25 BTC + fees (~$250K). Everyone else's work is wasted. Race resets every block.

⚖️

Self-Regulating Difficulty

Every 2016 blocks, difficulty adjusts to maintain 10-min block time. More hash rate = higher difficulty = same issuance rate (~900 BTC/day).

400 EH/s Network

Bitcoin network hash rate: 400 quintillion hashes/sec. Requires industrial-scale operations with specialized ASICs and cheap electricity (<$0.05/kWh).

🤝

Mining Pools Dominate

Solo mining takes years to find block. Pools provide daily payouts proportional to contribution. Top 4 pools control ~70% of hash rate.

💰

Profitability Equation

(Hash rate / Network rate) × Blocks/day × Reward × BTC price - Electricity cost. Margins thin at $0.10/kWh, excellent at $0.03/kWh.

⚠️

Centralization Risk

Geographic concentration (cheap energy) and pool dominance create centralization risks. Miners can switch pools, but ecosystem must stay vigilant.
