Can you solo mine Bitcoin with a MicroBT Whatsminer M73S?
Yes — a MicroBT Whatsminer M73S (500.85 TH/s) can solo mine Bitcoin (BTC) via a solo pool. At Bitcoin's 973.63 EH/s SHA-256 network that is about a 1-in-37 chance per year — expected one block roughly every 36.82 yr, for the full 3.1400 BTC (≈ 263,810 USD) block. BackPoW computes this from live network difficulty using a Poisson block-discovery model. Realistically this is a hobby/lottery play rather than an income strategy.
Hardware Tier & Ecosystem Ranking on Bitcoin
The MicroBT Whatsminer M73S is categorized in the Commercial / High-Yield Tier (Top quartile hashrate on this network, highly competitive for regular pool revenue or realistic solo mining.). Among all 22 tracked models on Bitcoin, it ranks #11 in electrical efficiency (69,562,500,000.00 H/W) and #2 in raw hashrate (500.85 TH/s).
Electricity Operating Costs & Breakeven
Running a MicroBT Whatsminer M73S (7,200 W) pulls about 172.80 kWh per day (5259.6 kWh per month). At the standard rate of 0.069 USD/kWh, electricity costs roughly 11.92 USD per day (362.91 USD/month or 4,355 USD/year). Statistically that year returns 0.03 blocks, worth about $7,165 — expected revenue covers the power bill about 1.6x over.
The operational breakeven threshold is 0.114 USD/kWh. Expected net operating margin at benchmark tariffs:
- At 0.040 USD/kWh (Hydro / Renewable): +12.71 USD / day
- At 0.069 USD/kWh (Standard Industrial): +7.69 USD / day
- At 0.120 USD/kWh (Residential Grid): -1.12 USD / day
Break-even Coin Price Target: For this hardware to break even on electricity, Bitcoin must trade at or above 51,064.83 USD at standard industrial power (0.069 USD/kWh), or 88,808.41 USD at residential power (0.120 USD/kWh).
Bankroll & Variance Risk Simulator
Solo mining block discovery follows a memoryless Poisson distribution. While the average wait is 36.82 yr, real-world dispersion ranges across 5% and 50% quantiles:
- Lucky streak (5% Odds): Block within ~1.89 yr (1-in-20 fastest discovery, power cost: ~8,225 USD)
- Median expectation (50% Odds): Block within ~25.52 yr (Nominal median, power cost: ~111,142 USD)
- Bad luck streak (5% Odds): Can stretch up to ~110 yr (1-in-20 extended dry spell, power cost: ~480,346 USD)
High Variance Alert: In a 1-in-20 severe drought (~110 yr), cumulative electricity burned (~480,346 USD) will exceed the block reward value (263,810 USD). Pool mining is recommended for risk-averse operators.
MicroBT Whatsminer M73S Price & Estimated ROI
Current market price: $6,866–$7,077 across 4 vendors (median $6,972). Mined against its most profitable coin instead of solo, it would pay itself back in about 673 days.

How the odds have moved
Bitcoin's network hashrate climbed 9% since 2026-09-08, from 893.10 EH/s to 973.63 EH/s — so the same rig is now 9% less likely to find a block.
Where to point a MicroBT Whatsminer M73S at Bitcoin
Solo mining still runs through a solo pool: it handles the block template and pays the full reward to whoever finds the block. BackPoW tracks 82 solo pools for Bitcoin with their stratum endpoints, fees, and pool hashrates — see Bitcoin solo mining pools:
- web.public-pool.io (Fee: 0% · Hashrate: 50.42 PH/s)
- pool.solomining.de (Fee: 0% · Hashrate: 7.91 PH/s)
- nexuspool.io (Fee: 0% · Hashrate: 5.80 PH/s)
How the odds are calculated
Because each hash succeeds independently, finding a block is a Poisson process — there is no 'due' block, only an average rate. The mean time between blocks is T = network_hashrate ÷ your_hashrate × block_time, and the realistic chance of at least one block over a period t is P = 1 − e^(−t/T). That is why a longer run raises your odds but never guarantees a block. For this pair: daily chance 0.0074%, yearly chance 2.68%.
