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.
