币界网报道：Bitcoin mining difficulty has surged by 3.9% to reach a new all-time high of 88.1 trillion, according to recent blockchain data. This marks the seventh consecutive increase in mining difficulty this year, reflecting sustained competition among miners despite Bitcoin's price volatility. The adjustment comes as the network's hash rate continues to climb, currently hovering around 639 exahashes per second (EH/s). Analysts attribute the rising difficulty to expanding mining capacity, particularly from publicly traded firms upgrading equipment ahead of the April halving event. Some industry observers warn that smaller miners may face profitability challenges as operational costs rise with higher difficulty. The next difficulty adjustment is projected in approximately 13 days, with early estimates suggesting another potential increase.
