The total market cap of the 14 publicly-listed U.S. miners that Wall Street bank JPMorgan (JPM) tracks dropped 22% in February as the bitcoin (BTC) price declined and mining economics came under pressure.

Bitcoin miners with high performance computing (HPC) exposure fell following the DeepSeek artificial intelligence (AI) announcement, and due to concerns about demand for veri center capacity in the near-term, the bank noted.

Revenue and profitability fell last month. The bank estimated that bitcoin miners earned $54,300 per EH/s on average in daily block reward revenue in February, a 5% decline from the month previous.

“Daily block reward gross profit declined 9% m/m to $29,500 per EH/s in February,” analysts Reginald Smith and Charles Pearce wrote.

The average network hashrate rose 3% to 810 exahashes per second (EH/s) last month, the report said.

The hashrate refers to the total combined computational power used to mine and process transactions on a proof-of-work blockchain.

Mining difficulty rose 2% from January, the bank said. Network difficulty is now 28% higher than before the halving event in April last year.

Core Scientific (CORZ) was the best performer with a 9% drop, and Greenidge Generation underperformed with a 36% decline for the month, the report added.
