Gate News reports that on March 22, Bitcoin mining difficulty at block height 941,472 (March 21) was adjusted downward by 7.76% to 133.79 T, marking the second-largest decrease this year, only behind the 11.16% drop on February 7. Currently, the network’s average hash rate over the past seven days is 937.76 EH/s. JPMorgan analysts estimated in February that, as high-cost operators exit, Bitcoin mining costs have fallen from $90,000 to $77,000, but remain above spot prices. An increasing number of publicly listed mining companies are shifting infrastructure from Bitcoin mining to AI computing businesses. Core Scientific stated that it plans to sell most of its Bitcoin holdings by 2026 to fund AI and high-performance computing expansion; Bitdeer fully liquidated its Bitcoin reserves to zero in February, and as of the week ending March 21, Bitdeer’s Bitcoin holdings remain at zero. Companies like Cango, Riot Platforms, TeraWulf, IREN, CleanSpark, and Bitfarms have also adopted similar diversification strategies in recent quarters.
