Bitcoin climbed nearly 3% in 24 hours to $81,282 Thursday morning in New York, extending a more than 23% gain over 30 days and lifting cryptocurrency-related stocks. Strategy, the Bitcoin treasury company, rose more than 13% after resuming purchases following a 10-week pause, while Coinbase gained 11%. HIVE Digital advanced 13%, MARA Holdings more than 10%, CleanSpark 9% and IREN 4%. Circle Internet Group shares also rose 13.15% to $100.30 in the earlier report, as stronger crypto markets supported sentiment around stablecoin activity. The broader rally followed U.S. Treasury plans to more than double government debt buybacks and President Donald Trump’s call for lawmakers to advance the crypto Clarity Act. Bitcoin exchange-traded funds attracted more than $2.8 billion, the highest inflow since October, while Bitcoin’s latest price remains nearly 40% below the $126,080 record cited in the report. Circle is also preparing to launch Arc, its proprietary mainnet, on Sept. 16 for institutional asset tokenization and cross-border payments.
