GPU Mining Profitability Analysis Guide for Guernsey
Cryptocurrency mining profitability depends on three primary variables: hardware hash rate, electricity cost, and network mining difficulty. As more miners join a network, the difficulty adjusts upward to maintain constant block times, reducing each miner's share of rewards proportionally. This is the compounding difficulty effect — a 3% monthly difficulty increase means mining revenue halves approximately every 23 months even if coin price stays flat.
In Guernsey, electricity costs are a critical factor. At £0.12/kWh, a 140W GPU costs $0.403/day to run. Any miner earning below that daily rate is operating at a loss. Use the break-even calculator to verify minimum required earnings before investing in hardware.
