Bitcoin Fees Supply Just 0.64% of Miner Revenue

Bitcoin (BTC) transaction fees accounted for just 0.64% of miner revenue over the past 30 days, leaving newly issued coins as the primary source of mining income and keeping profitability tied mainly to price and power costs.

The 30-day fee average was 0.65% one week earlier, marking only a small change. The measure has remained below 1% since mid-August 2025.

A sustained rise above 1% would show that fees are contributing more to miner revenue and would point to greater network activity. The current fee share alone does not establish that miners are shutting down equipment or selling reserves, as operating conditions vary by hardware, electricity rates and other expenses.

At an electricity cost of $0.05 per kilowatt-hour, mining one BTC with Bitmain’s Antminer S19 costs about $86,700 in power. The S21 requires about $44,300 in electricity per BTC.

Those estimates exclude equipment purchases, cooling and other expenses, so miners’ total costs are higher. The S19’s electricity cost exceeds Bitcoin’s price, while the S21 leaves more room for equipment, maintenance and other expenses.

Bitcoin was near $83,000 when the data was reported. The asset had gained 8% over 30 days but fallen more than 3% over seven days, remained 25% below its level a year earlier and sat nearly 34% below its all-time high of over $126,000.

The latest figures follow an earlier period in which Bitcoin miner revenue rebounded 78% from its July low as the asset recovered and network hashrate increased.
