Solo mining odds
The Bitmain Antminer S21E Hyd is built for pooled mining, not solo — at this hashrate solo mining is a curiosity, not a realistic strategy. The odds below are shown for context, computed exactly, not as a suggestion.
A win pays the full block subsidy plus fees. Pooled mining pays the same expected value in steady sats instead of one lump sum.

Questions
Is the Bitmain Antminer S21E Hyd profitable?
At $0.12/kWh, the 310 TH/s bin currently loses $5.54/day, before hardware cost. It's profitable below $0.0762/kWh — check the 3-tier table above against your real electricity rate for the exact answer at your cost.
What are the solo mining odds for the Bitmain Antminer S21E Hyd?
At 310 TH/s against the current network hashrate, the 310 TH/s bin has odds of 1 in 20,675 per day of finding a block on its own — expected once every 57 years. At this hashrate that's a curiosity, not a realistic plan — this device is built for pooled mining.
How does the Bitmain Antminer S21E Hyd compare on efficiency?
Efficiency (J/TH — energy per unit of hashing power) is shown per bin in the variant table above, derived directly from each SKU's power draw and hashrate. Lower is better: it means more BTC mined per watt of electricity, which is what actually drives the break-even price above.
How is profitability calculated?
Daily BTC = your hashrate ÷ network hashrate × 144 blocks/day × (subsidy + average tx fees). Revenue is that figure at the current BTC price. Electricity is watts × 24 ÷ 1,000 × your rate. No pool fee is assumed. Every input is editable in the full calculator.
How current are these numbers?
Price and network difficulty refresh hourly, and the timestamp at the bottom of this page shows the exact snapshot used. If a feed goes stale, the page marks itself stale rather than quietly serving an old figure as current.
