Bitcoin miner transaction fees represent only 0.64% of revenue, with block rewards dominating income as older mining hardware faces margin pressure.

Transaction fees generated only 0.64% of Bitcoin miner revenue over the most recent 30-day period, with block rewards from newly issued coins providing nearly all remaining income. At an electricity rate of $0.05 per kilowatt-hour, operating an Antminer S19 costs approximately $86,700 in power alone per BTC produced—exceeding the asset's current value. The more recent S21 model requires roughly $44,300 in electricity per coin, offering greater economic cushion, though both machine profitability remains sensitive to BTC price movements and individual operator cost structures.
The minimal fee contribution reflects network demand rather than miner distress. The 30-day average of 0.64% had remained below 1% since mid-August 2025, though BTC's recovery from $59,000 to the $83,000–$84,000 range has improved overall mining economics. A sustained return above 1% in fee revenue would signal rising network activity and greater transaction pressure on the blockchain.
Whether older equipment becomes economically unviable depends on further price direction and electricity costs specific to each operation. The analysis excludes hardware procurement and cooling expenses, meaning total per-coin production costs run higher than electricity figures alone. Some publicly traded miners have simultaneously diversified revenue through non-Bitcoin ventures, including significant allocations to artificial intelligence contracts, as traditional mining margins face structural headwinds.
