Jefferies Investment Bank reports a drop of over 7% in Bitcoin mining profitability in September

Jefferies highlighted that Bitcoin mining profitability declined by more than 7% in September 2025, driven by a 2% decrease in Bitcoin price and a significant 9% rise in network hash rate.

North American mining firms generated 3,401 Bitcoins that month, down from 3,576 in August. Mining revenue fell, with theoretical earnings for a hash rate of 1 EH/s at around 52,000 USD per day.
