Methodology: revenue = hashrate × network reward ÷ difficulty × EUR price, continuously updated (api.minent.eu, CoinGecko, Blockchair). Profit = revenue − electricity (0 €/kWh by default = gross revenue; enter your rate for net). Pool fees (1–2%) not deducted. Past performance does not guarantee future results — this is not financial advice.
