<p>The M70 series includes three efficiency tiers: 12.5 J/TH, 13.5 J/TH, and 14.5 J/TH.<br> MicroBT is offering both air-cooled and liquid-cooled versions. The entry-level M70 delivers about 214 TH/s, while the rack-mounted M79S exceeds 1 PH/s, targeting industrial-scale operators.</p>
<p>However, the launch arrives at a difficult moment. Bitcoin's hashprice has dropped to $35 per PH/s/day, near historical lows. The network hashrate remains above 1 ZH/s, and these conditions compress miner margins and slow hardware demand.</p>
<p>As a result, ASIC manufacturers face higher inventories and longer purchase cycles. Mining companies are more cautious, and many review long-term infrastructure decisions.</p>
<h3 class="wp-block-heading" id="main-drivers-of-the-weak-hardware-market">Main drivers of the weak hardware market:</h3>
<ul>
 <li>falling hashprice;</li>
 <li>rising operational costs;</li>
 <li>extended ASIC payback periods;</li>
 <li>a shift toward selective capital spending.</li>
</ul>

<p>During the presentation in Abu Dhabi, MicroBT highlighted sustainability. The company showed solar-ready systems and hybrid power models. According to founder Yang Zuoxing, the sector must prioritize energy efficiency instead of relying on bullish market cycles.</p>
<p>MicroBT also emphasized broader ecosystem partnerships. HashSmith was introduced as a new joint-mining collaborator. This aligns with a wider trend: Bitmain and Canaan increasingly operate their own mining capacity. Canaan, for example, recently launched the A16 series with 12.8 J/TH efficiency.</p>
<p>The new M70 lineup therefore marks a strategic shift toward long-term infrastructure and operational improvements.</p>
