Bitcoin’s mining difficulty fell to 126.23 trillion, marking a 19.1% decline from its November 2025 record high.
Bitcoin mining difficulty declined to 126.23 trillion, a 14% drop from its January peak and 1.1% below year-earlier levels. The adjustment reflects reduced network competition as miners scale back operations due to plunging revenues and shifting capital toward AI infrastructure.
The metric, which resets every 2,016 blocks to maintain 10-minute block times, last reached a record 155.97 trillion in November 2025. The 19.1% decline from that high underscores weak mining economics, with forward markets signaling no near-term recovery. Only once before has difficulty fallen below its year-ago level.
Falling difficulty suggests fewer miners are competing for block rewards, easing pressure on those remaining. The trend coincides with broader industry consolidation and capacity reductions in key mining regions.
