The post Bitcoin Network Mining Difficulty Sees Largest Percentage Increase Since 2021, Even As Crypto Market Weakness Persists ⋆ ZyCrypto appeared on BitcoinEthereumNews.com.

&nbsp Bitcoin mining difficulty, a measure of how computationally hard it is for miners to find a new block on the leading blockchain, has risen 14.7% to 144.4 trillion in the latest adjustment. This represents the largest absolute increase since 2021, when the China mining prohibition caused major disruption, following a 22% rise as the network recovered. ▲ 14.73% to 144.4T Bitcoin mining just got ~15% harder, with the largest ever increase in absolute difficulty, completely erasing last epoch’s huge downwards adjustment. pic.twitter.com/qRHDELO4n5 — mononaut (@mononautical) February 20, 2026 Bitcoin Difficulty Surges The adjustment occurred at block height 937,440, according to Bitcoin network explorer Mempool, reversing the previous epoch’s steep 11% drop. Mining difficulty adjusts every 2,016 blocks — roughly every two weeks — to keep block production around one every 10 minutes, regardless of fluctuations in the network’s hashrate. Data from Clark Moody’s dashboard shows that blocks were mined at an average of 8 minutes and 47 seconds during the most recent epoch — well below the 10-minute target — triggering the upward difficulty adjustment. Over the same period, the network’s hashrate climbed from roughly 884 EH/s to 1,030 EH/s, according to Mempool, indicating a significant boost in active mining capacity. Hash rate is the total computational power of all miners that secures the Bitcoin blockchain. Advertisement

&nbsp How Difficulty Adjustment Works In October, as Bitcoin hit a record high of $126,080, the network’s hashrate peaked at 1.1 zettahashes per second (ZH/s). By February, with prices threatening a $60,000 breakdown, the hashrate fell to 826 exahashes per second (EH/s). Since then, the hashrate has bounced back to 1 ZH/s, while Bitcoin’s price has recovered to roughly $66,893. However, the apex crypto remains 46.8% down from the October peak. Mining activity took its biggest hit since…
