Bitcoin's mining difficulty has fallen 18.5% from its peak, marking the biggest drop since the 2021 China crackdown on mining. This decline reflects miners shutting down operations due to Bitcoin's price dropping over 50% from its October 2025 high, making mining less profitable especially for those with older equipment and high energy costs. Some miners are shifting resources to AI tasks where contracts are more stable. The difficulty adjustment helps maintain a 10-minute block time despite changes in mining power, so this drop indicates fewer active miners securing the network. Market sentiment is pressured by falling AI stocks, but technical indicators suggest Bitcoin may be oversold heading into the weekend.
