币界网报道：Bitcoin mining difficulty has surged by 3.9% to reach a new all-time high of 86.39 trillion hashes, according to data from BTC.com. This marks the sixth consecutive increase in mining difficulty this year, reflecting growing competition among miners as they deploy more efficient hardware ahead of the April halving event. The adjustment follows Bitcoin's hash rate climbing to record levels above 700 EH/s in recent weeks. Analysts note the rising difficulty could squeeze profit margins for less efficient miners, potentially accelerating industry consolidation. The next difficulty adjustment is expected around April 24, coinciding with the halving that will reduce block rewards from 6.25 BTC to 3.125 BTC per block.
