Buy Antminer S21 Pro 220T — Is the Investment Worth It?
The Antminer S21 Pro 220T is the entry point to Bitmain's Pro series and offers all the benefits of the professional line at the lowest price within the range. At 220 TH/s and 16.0 J/TH efficiency it provides a solid foundation for profitable bitcoin mining in professional hosting. Unlike the standard series, even the entry model benefits from the optimized Pro firmware and improved cooling. For buyers who want to specifically enter the Pro series without needing the highest configurations, the Pro 220T is an economically smart choice.
Profitability with hosting power rates
At hosting power costs of €0.062/kWh, daily operating costs run about €5.22. On European home power at €0.30/kWh it would be €25.27 per day. At 3,510 W the Pro 220T is among the more efficient models in the Pro series, keeping running costs at a level that leaves room for profitability even in conservative BTC price scenarios.
The Pro 220T reaches the same hashrate as the Whatsminer M61S+ (220 TH/s) but draws 230 W less power. The 16.0 J/TH vs. 17.0 J/TH efficiency saves about €0.34 per day in hosting — over €120 per year less in power costs.

FAQ
Frequently asked questions about the Antminer S21 Pro 220T
The Pro series includes optimized firmware for stable 24/7 operation, improved thermal management with finer fan control, and stricter chip selection. Even the entry-level Pro 220T benefits from these improvements — failure rates in continuous operation are measurably lower than on the standard line.
At equal hashrate, the Pro variant offers higher operational stability and better thermal management. Power draw is comparable, but the Pro firmware ensures more constant hashrate over longer periods. For hosting operations, where uptime is decisive, the Pro premium pays off.
Payback time depends on current BTC price and network difficulty. Use our bitcoin mining calculator for a current calculation with live data. As a rule of thumb: at hosting power costs and stable BTC price, typical payback is between 12 and 18 months.
Yes, we offer upgrade options within the Pro series. If you later want to move to the Pro 225T or Pro 234T, we can take your existing miner in trade. So you start flexibly and scale when needed.
The miner connects to a standard C19 220 V power outlet and needs an Ethernet connection. In Minenity hosting the full infrastructure — power, network, cooling, rack space — is included in the hosting package. You handle nothing.
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.
