Bitdeer Launches SEALMINER DL1 Air ASIC Miner for Litecoin and Dogecoin
Bitdeer has unveiled the SEALMINER DL1 Air, a Scrypt-algorithm ASIC miner delivering 25 GH/s hashrate with air cooling, designed for industrial-scale LTC and DOGE mining.
Bitdeer returns to Scrypt mining with a new industrial-grade rig
Mining company Bitdeer has launched the SEALMINER DL1 Air, a new ASIC miner built for cryptocurrencies running the Scrypt hashing algorithm. The device supports mining of Litecoin, Dogecoin, and several smaller projects including Bellscoin, Junkcoin, Luckycoin, and Pepecoin.
«📢 Scrypt miners, this one's for you! SealMiner DL1 Air has arrived. Our return to Scrypt mining — engineered for industrial-scale performance. 25 GH/s hashrate, 149 J/GH power efficiency, Proven SEALMINER air-cooling design. Built for LTC & DOGE mining» — Bitdeer (@BitdeerOfficial), original post
The SEALMINER DL1 Air delivers up to 25 GH/s hashrate while consuming 3.7 kW of power, achieving an energy efficiency rating of 149 J/GH. The unit uses Bitdeer's proven air-cooling architecture and offers three performance modes, allowing operators to optimize for their specific conditions. According to the company, the device is engineered for industrial deployment and meets the reliability standards required by professional miners.
Why this matters
Bitdeer, founded by former Bitmain co-founder Jihan Wu, has rapidly scaled its Bitcoin mining operations over the past year. In January 2026, the company overtook MARA Holdings — the long-standing leader among public miners — in deployed Bitcoin hashrate. Bitdeer's capacity surged by more than 650% year-over-year, driven by mass deployment of its proprietary mining hardware.
The move into Scrypt hardware signals a product diversification push. Bitdeer first entered the Bitcoin mining equipment market in 2024 with the SEALMINER A1. Its third-generation SEALMINER A3 units now rival the flagship Antminer S21 and S23 lines in profitability, according to Bitmain-affiliated pool Antpool.
Jihan Wu received Bitdeer as part of a settlement package in early 2021, which also included the BTC.com mining pool, overseas data centers, and $600 million. The deal ended a prolonged conflict with his former Bitmain partner Micree Zhan.
Bitdeer sells all mined Bitcoin to fund expansion
Alongside its hardware expansion, Bitdeer has adopted a strategy of selling all mined Bitcoin. In February 2026, the company liquidated its entire crypto reserve — approximately 943.1 BTC — to fund new facility acquisitions, hashrate growth, and AI initiatives.
«Bitdeer BTC Weekly Update — BTC Holdings: 0 (pure holdings, excluding customer deposits), BTC Output: 158.8 BTC, BTC Sold: 158.8 BTC, Net BTC Added: 0 BTC. Data as of March 13, 2026.» — Bitdeer (@BitdeerOfficial), original post
The most recent weekly report confirms the same approach: 158.8 BTC mined and fully sold, with zero holdings on the balance sheet.
Bitcoin miners increasingly pivot toward AI
The broader trend of Bitcoin miners shifting toward AI computing services continues to accelerate. Trader Ran Neuner has raised concerns about potential threats to the Bitcoin network as mining capacity migrates elsewhere.
HIVE Digital Technologies, which operates 25.5 EH/s of Bitcoin hashrate, announced a gradual wind-down of crypto mining at its facility in Boden, Sweden, redirecting resources toward high-performance computing.
«Bitcoin mining generates cash flow. AI compute delivers high-margin recurring revenue. That's the dual-engine model at work. Nine time zones, three continents, renewable energy, and a contracts-first approach to growth.» — HIVE Digital Technologies (@HIVEDigitalTech), original post
Simultaneously, HIVE announced a fourfold expansion of its liquid-cooled AI data center capacity in Canada, increasing critical load from 4 MW to 16.6 MW. The company plans to deploy over 4,000 GPUs across owned and hosted facilities in Manitoba and British Columbia.
Analysts at Wintermute have previously stated that the traditional Bitcoin mining business model is losing relevance amid declining profitability. Bitdeer's launch of Scrypt mining hardware fits a broader pattern: mining firms are actively seeking new revenue streams, whether through alternative algorithms, AI compute services, or infrastructure expansion.
