最新报道:A U.S.-based mining operator has ordered 50,000 Avalon A15 Pro rigs from Canaan Inc., marking the manufacturer's largest single hardware sale in over three years, as Bitcoin mining difficulty hits a record 150.84 trillion. Canaan CEO Nangeng Zhang called the deal a vote of confidence in Bitcoin's future, emphasizing efficiency gains amid tightening profitability. With the U.S. accounting for 36% of global hashrate, this move signals intensified competition, likely driving industry consolidation as smaller miners struggle with rising costs and hardware demands.
