Bitcoin's mining difficulty dropped by 7.7% on March 20 to 133.79 trillion. The adjustment follows slower block production, with block times averaging 12 minutes 36 seconds, above Bitcoin’s 10-minute target. This change affects mining operations and may influence profitability. The next adjustment is estimated for April 3. Meanwhile, several miners are transitioning into AI and high-performance computing to seek steadier returns on power and data-center capacities.
Miners like Core Scientific, MARA Holdings, Hut 8, and Cipher Mining are shifting focus towards AI workloads, reducing hashrate, or shutting down inefficient rigs due to tightening profitability margins.
