For now, math works with miners. A strong hash rate, efficient hydro-cooled rigs and low-cost power supply keep margins intact even as the energy crisis takes hold. But this window depends on hard variables, electricity tariffs, network development and of course the price of Bitcoin. Today's profitability chart can be quickly sorted if anything materially changes. Until then, modern ACC fleets are operating sporadically with balance, efficiency and timing optimized.
