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 data. This marks the sixth consecutive increase in mining difficulty this year, reflecting heightened competition among miners as the network's hash rate continues to climb. The adjustment comes ahead of the highly anticipated Bitcoin halving event, expected around April 20, which will reduce block rewards from 6.25 BTC to 3.125 BTC. Analysts suggest the rising difficulty indicates strong miner confidence in Bitcoin's long-term value despite upcoming reward reductions. The current hash rate stands at approximately 639 EH/s, showcasing the network's robust security and growing infrastructure. Mining companies are increasingly deploying more efficient hardware to maintain profitability amid these challenging conditions.
