Bitcoin mining profitability in 2025 is highly sensitive to electricity prices. At residential rates above $0.12/kWh, most small-scale miners operate at a loss. Only industrial miners with access to sub-$0.06/kWh energy remain profitable. This trend highlights how rising energy costs have become the single biggest constraint on ROI. Mining is no longer viable as a hobby; it requires business-level planning, power contracts, and efficiency optimization.
