[Analysis: Bitcoin Miners' Transaction Fee Revenue Share Below 1%, Older Mining Machines Face Profitability Pressure] BlockBeats News, October 12, CryptoQuant analyst Axel Adler Jr. stated that over the past 30 days, Bitcoin transaction fee revenue has averaged only 0.64% of miners' total revenue, slightly down from 0.65% the previous week. This metric has remained below 1% since mid-August 2025. Currently, miners' income still primarily comes from newly issued Bitcoin, with transaction fees contributing minimally to profitability. As a result, miners' operational conditions largely depend on Bitcoin prices and mining machine efficiency. Although Bitcoin's price has rebounded from approximately $59,000 to $84,000, improving miners' operating environment, older mining machines still face significant profitability pressure under current electricity costs. If Bitcoin prices continue to rise, the electricity cost losses for older mining machines are expected to narrow, while the profit margins for high-efficiency mining machines may further expand. Conversely, if Bitcoin prices decline, miners' income will be impacted. Additionally, the transaction fee revenue share being below 1% does not directly indicate that miners are shutting down on a large scale or selling off reserves. If the transaction fee revenue share continues to rise above 1% in the future, it may suggest an improvement in the contribution of transaction fees to miners' income. It is worth noting that the above costs only account for electricity expenses and do not include other expenditures such as mining machine purchases, cooling facilities, and maintenance.
