The machine mines Litecoin and Dogecoin, as well as lesser-known altcoins Bellscoin, Junkcoin, Luckycoin and Pepecoin.
The SEALMINER DL1 Air uses air cooling, delivers up to 25 GH/s at 3.7 kW and achieves energy efficiency of 149 J/GH. The miner offers three performance modes to suit operating conditions.
“Designed for industrial deployment, the DL1 Air combines the engineering specifications and reliability required by professional miners,” the model description says.
In early 2021 Bitmain co-founder Jihan Wu received Bitdeer as part of a severance package that also included the BTC.com pool, crypto-mining data centres outside China and $600 million. His exit from Bitmain drew a line under a long-running conflict with former partner Micree Zhan.
It began with bitcoin
In 2024 Bitdeer entered the market for bitcoin-mining rigs with the SEALMINER A1.
According to the Bitmain-affiliated pool Antpool, third-generation SEALMINER A3 ASICs are currently the only machines that rival the flagship Antminer S21 and S23 lines on profitability.
In January 2026 Bitdeer overtook MARA Holdings—the long-time leader among listed firms—by deployed bitcoin hashrate. Over the year, the company’s capacity grew by more than 650%, driven by large-scale deployment of its own miners.
In February the firm reported in a weekly update that it had sold all mined and held coins—about 943.1 BTC. Bitdeer explained the liquidation of its crypto reserve by its intention to buy new sites to further increase hashrate and expand its artificial-intelligence initiatives.
According to the latest update, the company is sticking to a strategy of selling all bitcoins it mines—158.8 BTC for the week.

Miners’ AI pivot gathers pace
Bitcoin miners’ shift into higher-margin AI services is already causing unease in the community. Trader Ran Neuner warned of a threat to the network of the first cryptocurrency as capacity migrates.
HIVE Digital Technologies, with 25.5 EH/s of hashrate, said it is gradually winding down crypto mining at its site in Boden, Sweden. The firm will redirect resources to its high-performance computing strategy.
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.

At the same time, the company announced a fourfold expansion of liquid-cooled data-centre capacity for AI services in Canada. The facilities’ critical load will rise from 4 MW to 16.6 MW.
In total, HIVE expects to deploy more than 4,000 graphics processors at its own and hosted sites in the provinces of Manitoba and British Columbia.
Earlier, Wintermute specialists said the traditional business model of bitcoin miners had become outdated due to falling profitability.
