最新报道:Bitcoin mining stocks surged in pre-market trading as crypto legislation optimism grows. Marathon Digital (MARA) rose 2.3%, Riot Platforms (RIOT) gained 1.9%, and CleanSpark (CLSK) climbed 2.2% amid renewed investor interest in blockchain infrastructure plays. The rally comes as U.S. lawmakers advance bipartisan crypto regulation frameworks, though analysts caution the sector remains volatile with mixed performance across major tokens. Bitcoin itself held steady around $43,000, while Ethereum saw slight declines. Industry observers note growing institutional interest in mining operations as regulatory clarity improves, particularly for firms with sustainable energy strategies.
