Bitcoin Mining Fees Stay Below 1% of Revenue, Putting Financial Pressure on Older Rigs

Bitcoin (BITSTAMP:BTCUSD) transaction fees accounted for an average of just 0.64% of total daily mining revenue over the past 30 days, equivalent to 64 cents out of every $100 earned. The metric has consistently remained below 1% since mid-August 2025. With most mining income derived from newly issued tokens rather than transfer fees, miners rely heavily on token price appreciation and hardware efficiency to stay profitable.

Although Bitcoin recently climbed from $59,000 to around $84,000 before trading near $82,480, rising prices have not fully relieved financial strain on older hardware. Assuming power costs of $0.05 per kilowatt-hour, running older equipment such as Bitmain's Antminer S19 requires roughly $86,700 in electricity to mine one Bitcoin, exceeding current market prices. In contrast, newer models like the Antminer S21 incur electricity costs of about $44,300 per Bitcoin, offering substantially better margins even before accounting for cooling and maintenance expenses.

Low fee revenue alone does not immediately force miners to shut off rigs or sell Bitcoin, as individual profitability varies by power rates and maintenance overhead. Going forward, investors will watch whether higher Bitcoin prices or lower electricity expenses emerge to help operators running legacy hardware remain viable.
