Bitdeer Technologies Group has launched its SEALMINER A4 series, featuring the SEAL04 chip, achieving an energy efficiency of 9.45 J/TH. This marks a significant advancement in mining technology, introducing the industry to the "single-digit energy consumption era." Meanwhile, MARA Holdings is transitioning its mining operations to AI high-performance computing centers, partnering with Starwood Digital Ventures and acquiring a stake in Exaion. The global Bitcoin hashrate saw a 4% decline in Q1 2026, the first such drop in six years, as mining firms like Riot Platforms and Cango Inc. sell off Bitcoin holdings. Riot sold 3,778 BTC, exceeding its mining output, to cover capital expenditures, while Cango has liquidated over half its Bitcoin treasury. Additionally, Foundry Digital is launching a Zcash mining pool with KYC/AML compliance, expanding beyond Bitcoin.
