MicroBT releases new M70 series Bitcoin miners with an energy efficiency ratio of 12.5 J/TH

On Monday, MicroBT officially launched its new generation of WhatsMiner mining machines—the M70 series—in Abu Dhabi, introducing a more energy-efficient product line despite current Bitcoin mining profits being at multi-year lows. The M70 series covers three efficiency levels: 12.5 J/TH, 13.5 J/TH, and 14.5 J/TH, offering both air-cooled and water-cooled models. Individual machine hashrates range from the entry-level M70 at about 214 TH/s to the rack-mounted M79S at over 1 PH/s, targeting ultra-large-scale mining farms and advanced energy solutions.

This launch comes at a time when mining economics are extremely tight. According to market data, Bitcoin hash price has dropped to around $35 per PH/s/day, nearing historic lows; meanwhile, network hashrate remains above 1 ZH/s, further pressuring miners’ revenues. Record-high mining difficulty and price corrections have significantly slowed mining machine demand, with ASIC manufacturers generally facing challenges such as extended inventory and order cycles.

During this industry downturn, MicroBT has chosen to focus on long-term energy and system optimization rather than short-term market fluctuations. Company founder and CEO Yang Zuoxing pointed out that the future growth of Bitcoin mining will depend on continuous improvements in energy efficiency, including off-grid solar adoption, hybrid energy solutions, and modular deployment models, rather than betting on price cycles.

At the launch event, MicroBT also showcased progress in expanding its ecosystem toward a “joint mining” model, announcing a partnership with HashSmith. As the spot mining machine market shifts to a buyer’s market, manufacturers are increasingly pursuing strategies involving self-operated or jointly deployed hashrate. Previously, Bitmain and Canaan have ramped up their own mining operations, with Canaan’s A16 series released last year featuring 12.8 J/TH efficiency, indicating the industry’s move toward high-efficiency competition.

Despite the cyclical market downturn, MicroBT is using the M70 series to demonstrate its technical pathway for energy efficiency, system integration, and large-scale mining farm solutions, aiming to strengthen its competitive advantage in the next mining cycle.
