Solo mining odds

The MicroBT Whatsminer M73 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.

WindowOdds of a blockProbability
Per block1 in 1,944,8160.000051%
Per day1 in 13,5060.0074%
Per month1 in 4440.23%
Per year1 in 372.7%
Over 10 years1 in 424%
Expected time to one blockonce every 37 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

What electricity price does the MicroBT Whatsminer M73 need to break even?

$0.1157/kWh — below that rate, the 505 TH/s bin is profitable; above it, it loses money mining. At the site's $0.12/kWh reference rate it currently loses $0.722/day; enter your own electricity rate on this page for the exact number at your cost.

What are the solo mining odds for the MicroBT Whatsminer M73?

At 505 TH/s against the current network hashrate, the 505 TH/s bin has odds of 1 in 13,506 per day of finding a block on its own — expected once every 37 years. At this hashrate that's a curiosity, not a realistic plan — this device is built for pooled mining.

How does the MicroBT Whatsminer M73 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.
