最新报道:Bitcoin mining difficulty surged by 3.9% to a new all-time high of 88.1 trillion hashes, marking the sixth consecutive increase this year. The adjustment reflects growing competition among miners as the network's hash rate continues to climb. Analysts attribute the trend to improved mining hardware efficiency and institutional interest in Bitcoin ahead of the halving event. The next difficulty adjustment is expected in approximately two weeks, with further increases likely as miners expand operations. This upward trajectory underscores Bitcoin's robust security model despite rising operational costs for mining firms.
