Buy Sealminer A2 224T — Is the Investment Worth It?
The Sealminer A2 224T is the flagship of Bitdeer's in-house miner production and marks one of the world's largest mining companies entering the hardware market. Bitdeer, originally launched as a cloud-mining platform, brings its own chips and a thoughtful device design with the Sealminer A2. At 224 TH/s on just 3,300 W, the A2 224T reaches a remarkable 14.7 J/TH efficiency — better than all Whatsminer models and close to the Bitmain S21+. As a new market entrant, Bitdeer brings fresh competition to the ASIC market.
Profitability with hosting power rates
The Sealminer A2 224T draws only 3,300 W and runs in hosting at €0.062/kWh for daily power costs of about €4.91. By comparison: at European home power (€0.30/kWh), it would be €23.76 per day. The low running costs combined with high 14.7 J/TH efficiency make the A2 224T one of the most economical miners in the current lineup.
The Sealminer A2 224T undercuts the Whatsminer M61S+ by 440 W with 4 TH/s more hashrate — a clear efficiency edge of 14.7 vs. 17.0 J/TH. Bitdeer thus closes directly to the Bitmain S21+ and positions itself as a serious third force in the ASIC market.

FAQ
Frequently asked questions about the Sealminer A2 224T
Bitdeer is one of the largest bitcoin mining companies worldwide, founded by Jihan Wu (co-founder of Bitmain). The company has expanded from pure cloud mining to its own chip and hardware development. The Sealminer A2 is based on Bitdeer's own SEAL02 chip and is the result of years of investment in semiconductor research.
Bitdeer itself operates thousands of miners in its own data centers and has tested the A2 internally before market launch. Initial reports from professional use are positive. Plus, our data center technicians handle maintenance, so you get fast support if any issues arise.
Bitdeer's SEAL02 chip is built on an advanced manufacturing process that enables high hashrate at low energy demand. At 14.7 J/TH the A2 224T reaches efficiency that competes with Bitmain's best models — a remarkable result for a first effort in the ASIC field.
The A2 224T as the top model of the series is currently available on request. Demand for the flagship is high. Contact us for current lead times and availability — we can often secure units from the next production run on short notice.
Yes, our hosting infrastructure is manufacturer-agnostic. You can run Sealminer, Antminer, and Whatsminer in parallel in the same data center. Many clients deliberately use multiple manufacturers to diversify their mining portfolio.
Yes, the power supply (PSU) is integrated. No separate PSU needed — the miner connects directly to the data center power supply.
About 75 dB — comparable to a vacuum cleaner running. Not suitable for home use, which is why we offer professional hosting: your miner runs in the data center and you have no noise at home.
The miner uses the SHA-256 algorithm and can mine Bitcoin (BTC), Bitcoin Cash (BCH), and Bitcoin SV (BSV). Most professional miners choose Bitcoin as the most profitable option.
Yes, as a self-employed individual or business you can depreciate ASIC hardware over 3 years. Consult your tax advisor for your specific situation. For US-based businesses, Section 179 deductions and bonus depreciation may apply to qualifying mining equipment.
