The MicroBT Whatsminer M63S 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

How likely is a MicroBT Whatsminer M63S to find a Bitcoin block?

At 372 TH/s against 1023.96 EH/s of current network hashrate, the 372 TH/s bin has odds of 1 in 19,116 per day — expected once every 52 years. It's a real, nonzero chance, not a rounding error, but most solo miners never find a block.

What does winning actually pay?

The full block subsidy plus average transaction fees — currently 3.1413 BTC, worth about $260,763. It's paid in one lump sum on the block you find, not spread out.

Is solo mining ever worth it?

Not as an income strategy — the expected value is real but arrives, if ever, as one lump sum after a long unpredictable wait, not steady earnings. People solo mine for the lottery-ticket upside, to support network decentralization, or to run their own node/pool infrastructure. Pooled mining pays the same expected value in steady sats instead.

Do more devices improve the odds?

Yes, linearly — running 4 identical Whatsminer M63S units at once gives 4× the combined hashrate and therefore 4× the daily odds of 1 unit, all else equal. Use the device-count field in the solo calculator to model a real multi-device setup.
