How we rank
Market price is the median live ask for the model, or its efficiency band median from the Gulf ASIC Price Index times its hashrate when it has no priced ads. Profit assumes 1.5% monthly difficulty growth, 95% uptime, a 2% pool fee, a flat BTC price and the 2028 halving. This is not investment advice.
