Solo mining odds

The MicroBT Whatsminer M61s+ 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.

Per year1 in 751.3%
Over 10 years1 in 812%
Expected time to one blockonce every 75 years

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 MicroBT Whatsminer M61s+ profitable?

At $0.12/kWh, the 234 TH/s bin currently loses $4.18/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 MicroBT Whatsminer M61s+?

At 234 TH/s against the current network hashrate, the 234 TH/s bin has odds of 1 in 27,389 per day of finding a block on its own — expected once every 75 years. At this hashrate that's a curiosity, not a realistic plan — this device is built for pooled mining.

How does the MicroBT Whatsminer M61s+ 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.
