Bitcoin (BTC) miners’ daily revenue and gross profit rose for the second consecutive month in December, hitting the highest levels since April, JPMorgan (JPM) said in a research report on Monday.

Mining profitability increased as the rally in the world’s largest cryptocurrency continued to outpace network hashrate growth, the bank noted.

JPMorgan estimated that bitcoin miners earned an average of $57,100 per exahash per second (EH/s) in daily block reward revenue last month, 10% more than in November.

Still, «daily revenue and gross profit per EH/s is still 43% and 52% below pre-halving levels, respectively,» analysts Reginald Smith and Charles Pearce wrote.

The network hashrate grew by 6% in December to an average of 779 EH/s, the report said. Hashrate refers to the total combined computational power used to mine and process transactions on a proof-of-work blockchain.

Mining difficulty rose 7% from the month before and is now 27% higher than before the reward halving event in April, the bank said. The hashrate increased 54% in 2024, slower than 2023’s gain of 103%.

The total market cap of the 14 publicly listed bitcoin miners that the bank tracks declined 23% to $28 billion in December. The figure rose 52% in November.

TeraWulf (WULF) was the only miner that outperformed bitcoin last year, with a 136% gain, the report said. Bitcoin climbed about 120%.
