Can you solo mine Verus with a Samsung Galaxy S21?
Yes — a Samsung Galaxy S21 (5.80 MH/s) can solo mine Verus (VRSC) via a solo pool. At Verus's 446.46 GH/s VerusHash network that is about 3 blocks per year — expected one block roughly every 107 days, for the full 3.0000 VRSC 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 Verus
The Samsung Galaxy S21 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 Verus, it ranks #1 in electrical efficiency (483,285.00 H/W) and #2 in raw hashrate (5.80 MH/s).
Electricity Operating Costs & Breakeven
Running a Samsung Galaxy S21 (12 W) pulls about 0.29 kWh per day (8.8 kWh per month). At the standard rate of 0.069 USD/kWh, electricity costs roughly 0.02 USD per day (0.60 USD/month or 7 USD/year). Statistically that year returns 3.42 blocks, worth about $1.92 — you would burn roughly 4x more in electricity than that reward is worth.
The operational breakeven threshold is 0.018 USD/kWh. Expected net operating margin at benchmark tariffs:
- At 0.040 USD/kWh (Hydro / Renewable): -0.01 USD / day
- At 0.069 USD/kWh (Standard Industrial): -0.01 USD / day
- At 0.120 USD/kWh (Residential Grid): -0.03 USD / day
Break-even Coin Price Target: For this hardware to break even on electricity, Verus must trade at or above 0.7083 USD at standard industrial power (0.069 USD/kWh), or 1.23 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 107 days, real-world dispersion ranges across 5% and 50% quantiles:
- Lucky streak (5% Odds): Block within ~5 days (1-in-20 fastest discovery, power cost: ~0 USD)
- Median expectation (50% Odds): Block within ~74 days (Nominal median, power cost: ~1 USD)
- Bad luck streak (5% Odds): Can stretch up to ~320 days (1-in-20 extended dry spell, power cost: ~6 USD)
High Variance Alert: In a 1-in-20 severe drought (~320 days), cumulative electricity burned (~6 USD) will exceed the block reward value (1 USD). Pool mining is recommended for risk-averse operators.

Current market price: $120–$210 (estimated market price, median $160) (Hardware price estimated).
How other hardware compares on Verus
Devices in the same hashrate class, solo mining Verus at today's difficulty:
| Hardware | Hashrate | Expected block | Chance in 1 year |
|---|---|---|---|
| AMD Ryzen 9 3900X | 25.21 MH/s | 25 days | 100.00% |
How the odds have moved
Verus's network hashrate fell 46% since 2026-09-08, from 833.43 GH/s to 446.46 GH/s — so the same rig is now 46% more likely to find a block.
Where to point a Samsung Galaxy S21 at Verus
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 7 solo pools for Verus with their stratum endpoints, fees, and pool hashrates — see Verus solo mining pools:
- vipor.net (Fee: 2% · Hashrate: 42.14 GH/s)
- fastpool.xyz (Fee: 0.1%)
- skaffapool.nl (Fee: 0.3% · Hashrate: 6.21 KH/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 0.9309%, yearly chance 96.72%.
Frequently Asked Questions: Samsung Galaxy S21 on Verus
Can you solo mine Verus with a Samsung Galaxy S21?
Yes — a Samsung Galaxy S21 (5.80 MH/s) can solo mine Verus (VRSC) via a solo pool. At Verus's 446.46 GH/s VerusHash network that is about 3 blocks per year — expected one block roughly every 107 days, for the full 3.0000 VRSC block. BackPoW computes this from live network difficulty using a Poisson block-discovery model.
Is VerusHash ASIC-resistant, and where does the Samsung Galaxy S21 stand?
VerusHash is an ASIC-resistant GPU algorithm relying on memory bandwidth. The Samsung Galaxy S21 ranks #2 of 2 GPUs on Verus. It operates in the Mid-Range Tier (middle quartile), offering solid pool mining throughput with moderate solo variance.
What is the operating power cost and breakeven electricity rate for a Samsung Galaxy S21 on Verus?
At 12 W, operating a Samsung Galaxy S21 consumes 0.29 kWh/day (8.8 kWh/month). At standard electricity (0.069 USD/kWh), the power bill is 0.02 USD/day (0.60 USD/month). The operational breakeven threshold is 0.018 USD/kWh.
What happens if my Samsung Galaxy S21 encounters a severe dry spell on Verus?
Block discovery is an independent Poisson process with no memory. In a 1-in-20 bad luck drought (5% worst luck), finding a block can stretch up to 320 days, accumulating roughly 6 USD in power costs.
