Bitdeer mined 636 BTC in December 2025, implying a realized hashrate of 51.2 EH/s and marking a 20% increase from November. The company attributes the rise to the continued energization of its proprietary SEALMINER fleet, which pushed more capacity into operation. On a production basis, that performance placed Bitdeer close behind MARA for the month.
Bitdeer's December 2025 Bitcoin Production
December’s output of 636 BTC implies a realized hashrate of 51.2 EH/s for Bitdeer, reflecting a month-over-month jump of 20%. The company said the improvement was driven by bringing more SEALMINER units online, boosting uptime and throughput as deployment continued. For context on the company's recent month-to-month progress, see the November 2025 report that details prior production and plans.
Comparison with MARA
MARA Pool mined 675 BTC in December, which implies a realized hashrate of roughly 52 EH/s. When MARA’s share of joint-venture operations is factored in, the company remains the largest public miner by realized hashrate based on available data, though Bitdeer’s December results narrowed the gap. Bitdeer’s progress suggests the two firms are now in closer competition for the top spot among public miners.
Bitdeer's Hashrate and Deployment
Bitdeer reported its deployed proprietary hashrate reached 55.2 EH/s by month-end, with an additional 1.7 EH/s delivered but not yet energized. Beyond its own rigs, the company said total hashrate under management reached 71 EH/s in December, reflecting rapid SEALMINER deployment and a shift away from older third-party machines. The firm has been accelerating deployment of its hardware, including new sites such as the SEALMINER site in Nevada, which contributes to growing managed capacity.
Competition with Other Miners
Bitdeer’s December performance placed it ahead of several peers on a realized-production basis. CleanSpark previously reported mining 622 BTC in December, implying a realized hashrate of about 47.1 EH/s, which leaves it behind Bitdeer based on month-end production data. The same comparison indicates Bitdeer has overtaken IREN to become the second-largest public miner by realized hashrate for the time being.
Market Conditions and Future Outlook
Bitcoin mining economics remained under pressure as network difficulty stayed elevated and hashprice remained compressed, which the report notes is still below the $40/PH/s threshold. If Bitdeer sustains higher uptime while additional SEALMINER units are energized, that could intensify competition with MARA in coming months. The company’s shift toward proprietary hardware and retirement of older third-party rigs underpins its recent gains.
Why this matters
For individual miners in Russia with anywhere from a single rig to a modest farm, shifts at the top public miners change the competitive landscape but do not directly alter household operations. Higher deployment of efficient proprietary rigs by large players can gradually influence network difficulty and hashprice, which affects rewards per hash regardless of the operator. At the same time, a rise in managed hashrate means more capacity is controlled by operators who can optimize uptime and costs at scale, potentially widening the efficiency gap between large and small miners.
What to do?
- Track realized hashprice and difficulty regularly to see how changes in large operators’ capacity affect your income; adjust operating hours or farm size if rewards per PH/s decline.
- Prioritize uptime and maintenance on your own equipment—consistent operation can offset some pressure from compressed hashprice, especially for small fleets.
- Consider hardware efficiency when upgrading: redeploying older third-party rigs may be less competitive compared with newer proprietary models entering the network.
- Keep liquidity for power and repairs; if network rewards compress further, short-term cash buffers help you avoid forced sales or downtime.
