CryptoQuant analyst Axel Adler Jr. stated that in the past 30 days, Bitcoin transaction fee income accounted for 0.64% of miners' total income, and this indicator has remained below 1% since mid August 2025. At present, miners' income mainly comes from newly issued Bitcoin, and their operating conditions depend on Bitcoin prices and mining machine energy efficiency. Despite the price of Bitcoin rebounding from around $59000 to $84000, old mining machines still face profit pressure under current electricity prices. The above costs only include electricity bills and do not include expenses for purchasing mining machines, cooling facilities, and maintenance.
