Buy Sealminer A2 220T — Is the Investment Worth It?
The Sealminer A2 220T is the most affordable entry point to Bitdeer's A2 series and makes the advanced SEAL02 chip technology accessible to a wider audience. At 220 TH/s and 15.0 J/TH efficiency it delivers surprisingly strong performance for an entry model. The lower price comes purely from chip selection — the hardware platform is identical to the 224T. For buyers who want to test Bitdeer as a manufacturer or look for a cost-effective fleet addition, the A2 220T is the right entry point.
Profitability with hosting power rates
Like all models in the A2 series, the 220T draws exactly 3,300 W, which at hosting costs of €0.062/kWh translates to €4.91 daily. At European home power (€0.30/kWh) it would be €23.76. The A2 220T shares the lowest power costs in the lineup with the Whatsminer M60S+ and the other A2 variants — a clear advantage for long-term operation.
The A2 220T is the cheapest Sealminer and offers the same hashrate as the Antminer S21 Pro 220T at 210 W less power draw (3,300 vs. 3,510 W). Per euro of daily power cost, it delivers more hashrate than any Whatsminer — a strong argument for Bitdeer's entry model.

FAQ
Frequently asked questions about the Sealminer A2 220T
Only 4 TH/s of hashrate. The hardware is identical: same chip, same power draw, same dimensions, same connectors. The difference comes from natural variation in chip manufacturing. In daily revenue the difference is just a few cents.
Yes, the A2 220T is an excellent entry-level miner. The favorable price reduces financial risk, while low power costs of €4.91 per day in hosting provide a solid foundation. Combined with Minenity hosting, all technical hurdles disappear completely.
No, a later hashrate upgrade isn't possible since the difference lies in chip performance. But you can switch to an A2 222T or 224T model at any time — we'll take your existing miner in trade.
Bitdeer has tested the A2 in its own data centers under continuous load. Reports from professional use show stable performance over months. The identical hardware platform across all A2 variants means long-term experience from the 224T transfers directly to the 220T.
The A2 220T delivers 14 TH/s more hashrate than the M60S+ (220 vs. 206 TH/s) at identical 3,300 W power draw. The better 15.0 vs. 16.0 J/TH efficiency means more bitcoin per euro of power spent. The price premium is recouped through higher daily revenue.
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.
