Bitcoin Mining Profitability Basics
Mining profitability depends on hash rate, energy efficiency, electricity cost, Bitcoin price, and network difficulty. Profitability changes daily as difficulty adjusts every ~2016 blocks (roughly every 2 weeks).
Key Terms
- Hash Rate (TH/s): Your miner's computational power. More = higher chance of finding blocks.
- Power Efficiency: J/TH — lower is better. Modern ASICs: 20–30 J/TH.
- Break-even electricity cost: At ~$0.05/kWh most miners are profitable; at $0.15+ many are not.
