Bitcoin mining difficulty has fallen about 18.5% from the peak recorded on July 16, marking the network's largest drawdown since the 2021 China ban. The metric reflects how hard it is for miners to add new blocks and typically adjusts with changes in hashpower, or the computing power securing the network. The latest decline is smaller than the 32% drop from peak levels during the 2018 bear market and the 45% fall seen in 2021, but historically sharp difficulty declines have often coincided with cycle bottom areas. At the same time, prolonged bearish conditions could deepen pressure on miners and trigger capitulation selling, while a rebound after that phase could help set up a bullish reversal.
