最新报道: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 difficulty this year, reflecting heightened competition among miners as the network's hash rate continues to climb. The adjustment comes ahead of the upcoming Bitcoin halving event, which will reduce block rewards by 50%. Analysts suggest the rising difficulty indicates strong miner confidence in Bitcoin's long-term value proposition despite potential short-term profitability pressures post-halving. The network's security level now stands at unprecedented levels due to the increased computational power dedicated to mining operations.
