最新报道:Bitcoin mining difficulty has surged by 3.9%, reaching a new all-time high of 88.1 trillion hashes. This marks the sixth consecutive increase in difficulty this year, reflecting heightened competition among miners as the network adjusts to maintain a 10-minute block time. The rise follows Bitcoin's recent halving event, which reduced block rewards by 50%. Despite the increased difficulty, mining profitability remains stable due to higher transaction fees and Bitcoin's price resilience. Major mining firms continue to invest in more efficient hardware to maintain margins, signaling ongoing confidence in the sector's long-term viability.
