How to Use This Ranking
CoinWarz ranks miners by net daily profit per watt - not raw hashrate or sticker profit - so you can see which ASICs earn the most from a fixed watt budget. Power-limited operations (home miners, small facilities) should prioritize high $/W ASICs. Large farms can also consider raw hashrate per dollar.
Electricity cost is the biggest variable. A 2,780 W miner costs $6.67/day at $0.10/kWh, $3.34/day at $0.05/kWh, and $2.23/day at $0.03/kWh. Use CoinWarz's mining calculator to model your exact rate.
