最新报道:JPMorgan has increased its price targets for several Bitcoin mining firms, including CleanSpark (CLSK) to $14 from $12, Riot Platforms (RIOT) to $14 from $13, and MARA Holdings (MARA) to $19 from $18, citing higher Bitcoin prices and improved mining profitability. Analysts Reginald Smith and Charles Pearce noted the adjustments reflect a 24% rise in the bank's spot Bitcoin price assumption and a 9% increase in its network hashrate estimate. The hashrate, indicating computational power in proof-of-work blockchains, serves as a measure of industry competition and mining difficulty. JPMorgan maintains overweight ratings for CleanSpark, IREN (IREN), and Riot, while keeping neutral ratings for Cipher Mining (CIFR) and MARA. The bank highlighted improved Bitcoin mining profitability in May as a key factor in its revised targets.
