最新报道:Bitcoin mining difficulty has dropped by 5.7% to 83.1T, marking the largest decrease since the aftermath of FTX's collapse in December 2022. The adjustment follows a period of reduced network hash rate, likely influenced by miners scaling back operations ahead of the Bitcoin halving event. This difficulty retarget represents the most significant downward adjustment in nearly 18 months, potentially offering temporary relief to miners facing compressed profit margins. The change comes as the Bitcoin network prepares for its quadrennial halving, which will further reduce block rewards from 6.25 BTC to 3.125 BTC per block.
