Can you solo mine Kerrigan-X11 with a Bitmain Antminer D7?
Yes — a Bitmain Antminer D7 (1.29 TH/s) can solo mine Kerrigan-X11 (KRG) via a solo pool. At Kerrigan-X11's 2.56 TH/s X11 network that is about 33,027 blocks per year — expected one block roughly every 15.9 min, for the full 5.0000 KRG block. BackPoW computes this from live network difficulty using a Poisson block-discovery model. Realistically this is genuinely worth a patient solo run.
Hardware Tier & Ecosystem Ranking on Kerrigan-X11
The Bitmain Antminer D7 is categorized in the Mid-Range Workhorse Tier (Middle quartile hashrate offering solid pool mining throughput with moderate solo variance.). Among all 2 tracked models on Kerrigan-X11, it ranks #2 in electrical efficiency (408,554,193.14 H/W) and #2 in raw hashrate (1.29 TH/s).
Electricity Operating Costs & Breakeven
Running a Bitmain Antminer D7 (3,148 W) pulls about 75.55 kWh per day (2299.6 kWh per month). At the standard rate of 0.069 USD/kWh, electricity costs roughly 5.21 USD per day (158.67 USD/month or 1,904 USD/year). Statistically that year returns 33,027.08 blocks, worth about $1,495 — you would burn roughly 1x more in electricity than that reward is worth.
The operational breakeven threshold is 0.054 USD/kWh. Expected net operating margin at benchmark tariffs:
- At 0.040 USD/kWh (Hydro / Renewable): +1.07 USD / day
- At 0.069 USD/kWh (Standard Industrial): -1.12 USD / day
- At 0.120 USD/kWh (Residential Grid): -4.97 USD / day
Break-even Coin Price Target: For this hardware to break even on electricity, Kerrigan-X11 must trade at or above 0.0115 USD at standard industrial power (0.069 USD/kWh), or 0.0201 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 15.9 min, real-world dispersion ranges across 5% and 50% quantiles:
- Lucky streak (5% Odds): Block within ~49 s (1-in-20 fastest discovery, power cost: ~0 USD)
- Median expectation (50% Odds): Block within ~11.0 min (Nominal median, power cost: ~0 USD)
- Bad luck streak (5% Odds): Can stretch up to ~47.7 min (1-in-20 extended dry spell, power cost: ~0 USD)
High Variance Alert: In a 1-in-20 severe drought (~47.7 min), cumulative electricity burned (~0 USD) will exceed the block reward value (0 USD). Pool mining is recommended for risk-averse operators.

How other hardware compares on Kerrigan-X11
Devices in the same hashrate class, solo mining Kerrigan-X11 at today's difficulty:
| Hardware | Hashrate | Expected block | Chance in 1 year |
|---|---|---|---|
| Bitmain Antminer D9 | 1.77 TH/s | 11.6 min | 100.00% |
How the odds have moved
Kerrigan-X11's network hashrate climbed 38% since 2026-09-08, from 1.85 TH/s to 2.56 TH/s — so the same rig is now 38% less likely to find a block.
How the odds are calculated
Solo mining is memoryless: every hash is an independent lottery ticket, so the wait for a block follows an exponential distribution rather than a fixed schedule. On average a block takes T = network_hashrate ÷ your_hashrate × block_time, and the probability of finding at least one within a window t is P = 1 − e^(−t/T). BackPoW uses this Poisson relation instead of a naive linear estimate. For this pair: daily chance 100.00%, yearly chance 100.00%.
Frequently Asked Questions: Bitmain Antminer D7 on Kerrigan-X11
Can you solo mine Kerrigan-X11 with a Bitmain Antminer D7?
