New high–energy-efficiency ASICs enter the market as bitcoin hashprice hits historic lows.

On December 8, during the Bitcoin MENA 2025 conference, bitcoin mining hardware manufacturer MicroBT unveiled its latest generation of WhatsMiner devices in Abu Dhabi.

The new product lineup is structured across three energy-efficiency tiers: 12.5 J/TH, 13.5 J/TH, and 14.5 J/TH. Each tier includes multiple configurations, with both air-cooled and liquid-cooled options.

According to the technical documentation released by the company, performance ranges from roughly 214 TH/s for entry-level, air-cooled M70 models to more than 1 PH/s for high-capacity, rack-mounted M79S units.

The launch comes at a particularly challenging moment for the mining industry. Bitcoin hashprice—the metric measuring miners’ revenue per unit of hashrate—has fallen to around $35 per PH/s per day, nearing some of the lowest levels ever recorded. This environment is driven by a network hashrate that remains consistently above 1 ZH/s, combined with the recent correction in bitcoin’s price.

Despite these headwinds, MicroBT emphasized long-term structural improvements, including integration with off-grid solar systems and hybrid power supply models. Founder and CEO Yang Zuoxing stated that the sector’s growth will depend on continued gains in energy efficiency rather than reliance on market cycles.

The company also highlighted a strategic shift toward broader ecosystem partnerships, including direct participation in joint mining operations. MicroBT announced HashSmith as a new partner for co-mining—an important development as major manufacturers increasingly distribute or co-distribute their machines directly.

Bitmain and Canaan have already adopted proprietary mining operations or hosted hashrate structures since the previous bear market. Last October, Canaan announced its A16 series with an efficiency of 12.8 J/TH, placing it in direct competition with MicroBT’s latest offering.
