Antminer S21 Hyd 335Th Profitability: Is It Worth Mining Bitcoin in 2025?
What Is the Antminer S21 Hyd 335Th Profitability in 2025?
If you're researching the Antminer S21 Hyd 335Th profitability, you're looking at one of Bitmain's most powerful hydro-cooled Bitcoin ASIC miners on the market. With a hashrate of 335 TH/s at 5360W power consumption, this miner is engineered for serious data center operations and professional Bitcoin mining setups.
Antminer S21 Hyd 335Th Specs Overview
Before diving into profitability numbers, here are the key specifications of the Antminer S21 Hyd 335Th:
- Hashrate: 335 TH/s (SHA-256)
- Power Consumption: 5360W
- Efficiency: ~16 J/TH
- Cooling: Hydro (water-cooled)
- Algorithm: SHA-256 (Bitcoin, Bitcoin Cash, BSV)
- Noise Level: Extremely low thanks to liquid cooling
Is the Antminer S21 Hyd 335Th Profitable?
Profitability depends on several variables: your electricity cost, Bitcoin price, and network difficulty. At $0.05/kWh (common in Canada with hosting), the S21 Hyd 335Th can generate strong daily returns. At $0.10/kWh, margins tighten but the miner remains competitive due to its high efficiency ratio. The hydro-cooling system also eliminates costly HVAC infrastructure, reducing total operational costs significantly compared to air-cooled miners.
Why Choose the S21 Hyd Over Air-Cooled Miners?
The S21 Hydro series uses liquid cooling to maintain optimal chip temperatures, allowing Bitmain to push hashrates higher while keeping power efficiency excellent. This means better Antminer S21 Hyd 335Th profitability over time — especially during Bitcoin bull markets when every TH/s counts. Compared to the standard S21, the hydro version operates silently and with greater thermal stability, making it ideal for co-location and hosted mining in Canada.
