U.S.-listed bitcoin (BTC) miners accounted for 25.3% of the global network in December, Jefferies said in a research report on Thursday.
The bank cut its price target for MARA Holdings (MARA) to $20 from $24, while maintaining its hold rating on the stock. The shares rose 0.5% to $18.43 during early trading Friday.
Mining profitability improved in December as the average price of bitcoin gained 15%, outpacing the increase in the network hashrate, which was 6.5% higher, the report said.
