币界网报道：Bitcoin mining difficulty has surged by 3.9% to reach a new all-time high of 88.1 trillion hashes, according to recent data. This marks the sixth consecutive increase in mining difficulty this year, reflecting heightened competition among miners as more computing power joins the network. The adjustment follows Bitcoin’s fourth halving event in April, which reduced block rewards from 6.25 BTC to 3.125 BTC. Despite the reduced rewards, miners continue to expand operations, with publicly traded mining firms investing heavily in new equipment to maintain profitability. Analysts suggest the rising difficulty underscores Bitcoin’s robust security model, as higher hash rates make the network more resistant to attacks. However, smaller miners may face increasing pressure due to higher operational costs. The next difficulty adjustment is expected in about two weeks.
