97.80 MH/s · Etchash · network 172.01 TH/s. A GeForce RTX 3080 solo mining EthereumClassic (ETC) has about a 1-in-1 chance per year, i.e. an expected block roughly every 276 days for the full 1.5900 ETC (≈ 13 USD) reward.

GeForce RTX 3080 on EthereumClassic — Mining Truth Benchmark & Specifications

Consolidated PoW oracle metrics for operating a GeForce RTX 3080 on EthereumClassic (ETC) at live network difficulty and benchmark industrial electricity (0.069 USD/kWh):

Can you solo mine EthereumClassic with a GeForce RTX 3080?

Yes — a GeForce RTX 3080 (97.80 MH/s) can solo mine EthereumClassic (ETC) via a solo pool. At EthereumClassic's 172.01 TH/s Etchash network that is about a 1-in-1 chance per year — expected one block roughly every 276 days, for the full 1.5900 ETC (≈ 13 USD) 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 EthereumClassic

The GeForce RTX 3080 is categorized in the Mid-Range Workhorse Tier (Middle quartile hashrate offering solid pool mining throughput with moderate solo variance.). Among all 14 tracked models on EthereumClassic, it ranks #7 in electrical efficiency (407,516.67 H/W) and #10 in raw hashrate (97.80 MH/s).

Electricity Operating Costs & Breakeven

Running a GeForce RTX 3080 (240 W) pulls about 5.76 kWh per day (175.3 kWh per month). At the standard rate of 0.069 USD/kWh, electricity costs roughly 0.40 USD per day (12.10 USD/month or 145 USD/year). Statistically that year returns 1.32 blocks, worth about $16.69 — you would burn roughly 9x more in electricity than that reward is worth.

The operational breakeven threshold is 0.008 USD/kWh. Expected net operating margin at benchmark tariffs:

• At 0.040 USD/kWh (Hydro / Renewable): -0.18 USD / day
• At 0.069 USD/kWh (Standard Industrial): -0.35 USD / day
• At 0.120 USD/kWh (Residential Grid): -0.65 USD / day

Break-even Coin Price Target: For this hardware to break even on electricity, EthereumClassic must trade at or above 68.96 USD at standard industrial power (0.069 USD/kWh), or 119.93 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 276 days, real-world dispersion ranges across 5% and 50% quantiles:

• Lucky streak (5% Odds): Block within ~14 days (1-in-20 fastest discovery, power cost: ~6 USD)
• Median expectation (50% Odds): Block within ~191 days (Nominal median, power cost: ~76 USD)
• Bad luck streak (5% Odds): Can stretch up to ~2.26 yr (1-in-20 extended dry spell, power cost: ~328 USD)

High Variance Alert: In a 1-in-20 severe drought (~2.26 yr), cumulative electricity burned (~328 USD) will exceed the block reward value (13 USD). Pool mining is recommended for risk-averse operators.

GeForce RTX 3080 Price & Estimated ROI

Current market price: $330–$410 (estimated market price, median $370) (Hardware price estimated). Mined against its most profitable coin instead of solo, it would pay itself back in about 123 days.

How other hardware compares on EthereumClassic

How the odds have moved

EthereumClassic's network hashrate climbed 18% since 2026-09-22, from 145.48 TH/s to 172.01 TH/s — so the same rig is now 18% less likely to find a block.

Where to point a GeForce RTX 3080 at EthereumClassic

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 13 solo pools for EthereumClassic with their stratum endpoints, fees, and pool hashrates — see EthereumClassic solo mining pools:

• herominers.com (Fee: 0.9% · Hashrate: 223.07 GH/s)
• woolypooly.com (Fee: 0.9% · Hashrate: 24.27 GH/s)
• k1pool.com (Fee: 1% · Hashrate: 303.31 GH/s)

How the odds are calculated

Each hash is an independent attempt, so block discovery is memoryless and follows an exponential distribution. The average time to a block is T = network_hashrate ÷ your_hashrate × block_time. The chance of hitting at least one block within a period t is then given by the Poisson relation P = 1 − e^(−t/T) — the realistic probability, not a misleading linear one. For this pair: daily chance 0.3618%, yearly chance 73.39%.

Frequently Asked Questions: GeForce RTX 3080 on EthereumClassic

Can you solo mine EthereumClassic with a GeForce RTX 3080?

Yes — a GeForce RTX 3080 (97.80 MH/s) can solo mine EthereumClassic (ETC) via a solo pool. At EthereumClassic's 172.01 TH/s Etchash network that is about a 1-in-1 chance per year — expected one block roughly every 276 days, for the full 1.5900 ETC (≈ 13 USD) block. BackPoW computes this from live network difficulty using a Poisson block-discovery model.

Is Etchash ASIC-resistant, and where does the GeForce RTX 3080 stand?

Etchash is an ASIC-resistant GPU algorithm relying on memory bandwidth. The GeForce RTX 3080 ranks #10 of 14 GPUs on EthereumClassic. 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 GeForce RTX 3080 on EthereumClassic?

At 240 W, operating a GeForce RTX 3080 consumes 5.76 kWh/day (175.3 kWh/month). At standard electricity (0.069 USD/kWh), the power bill is 0.40 USD/day (12.10 USD/month). The operational breakeven threshold is 0.008 USD/kWh.

What happens if my GeForce RTX 3080 encounters a severe dry spell on EthereumClassic?

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 2.26 yr, accumulating roughly 328 USD in power costs.
