Understanding SHA-256 Mining
SHA-256 (Secure Hash Algorithm 256-bit) is the proof-of-work algorithm that secures the Bitcoin network. Developed by the NSA, it's considered one of the most secure cryptographic functions available.
When choosing a SHA-256 miner, efficiency (measured in J/TH) is the most critical factor. Lower efficiency means lower electricity costs and higher profitability. Modern miners like the Antminer S21 Pro achieve efficiencies below 16 J/TH, a significant improvement over older generations.
Bitcoin mining difficulty adjusts every 2016 blocks (~2 weeks), so investing in the most efficient hardware ensures long-term profitability even as competition increases.
Buyer's Guide: What to Look For
- Efficiency (J/TH) is king - lower is better for long-term profitability
- Consider your electricity costs - at $0.10/kWh, efficiency matters more than raw hashrate
- Hydro-cooled units offer better efficiency but require infrastructure
- Always factor in shipping, import duties, and setup costs
- Check warranty terms - reputable sellers offer 180+ day coverage
