Bitcoin mining difficulty falls 11.16% to 125.86 trillion, largest drop since China's 2021 crackdown

Bitcoin's mining difficulty was reduced by 11.16% to 125.86 trillion at block height 935,424, marking the biggest negative adjustment since China's 2021 mining ban and reportedly the tenth largest in the network's history. Over the past month the hashrate has fallen about 20% amid a sharp bitcoin price decline and Winter Storm Fern‑related shutdowns, pushing hashprice to fresh all-time lows and leaving many older mining rigs close to or below breakeven.
