Bitcoin ($BTC) mining profitability fell 7.4% in March, investment bank Jefferies said in a research report Friday.
The drop was due to a 11.2% decline in the average bitcoin price and a 9.1% drop in transaction fees, the report said.
U.S.-listed miners mined 3,534 bitcoin in March versus 3,002 in February, Jefferies said, and these companies accounted for 24.8% of the total network last month, compared to 23.6% the month previous.
