Solo mining odds — GeForce RTX 4090 on BitcoinZ

185.00 H/s · Zhash · network 10.34 KH/s. A GeForce RTX 4090 solo mining BitcoinZ (BTCZ) has about 3,596 blocks per year, i.e. an expected block roughly every 2.4 hours for the full 3,125.0000 BTCZ reward.

Can you solo mine BitcoinZ with a GeForce RTX 4090?

Yes — a GeForce RTX 4090 (185.00 H/s) can solo mine BitcoinZ (BTCZ) via a solo pool. At BitcoinZ's 10.34 KH/s Zhash network that is about 3,596 blocks per year — expected one block roughly every 2.4 hours, for the full 3,125.0000 BTCZ 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 BitcoinZ

The GeForce RTX 4090 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 5 tracked models on BitcoinZ, it ranks #1 in electrical efficiency (0.74 H/W) and #1 in raw hashrate (185.00 H/s).

Electricity Operating Costs & Breakeven

Running a GeForce RTX 4090 (250 W) pulls about 6.00 kWh per day (182.6 kWh per month). At the standard rate of 0.069 USD/kWh, electricity costs roughly 0.41 USD per day (12.60 USD/month or 151 USD/year). Statistically that year returns 3,595.65 blocks, worth about $247 — expected revenue covers the power bill about 1.6x over.

The operational breakeven threshold is 0.113 USD/kWh. Expected net operating margin at benchmark tariffs:

• At 0.040 USD/kWh (Hydro / Renewable): +0.44 USD / day
• At 0.069 USD/kWh (Standard Industrial): +0.26 USD / day
• At 0.120 USD/kWh (Residential Grid): -0.04 USD / day

Break-even Coin Price Target: For this hardware to break even on electricity, BitcoinZ must trade at or above 0.0000 USD at standard industrial power (0.069 USD/kWh), or 0.0000 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 2.4 hours, real-world dispersion ranges across 5% and 50% quantiles:

• Lucky streak (5% Odds): Block within ~7.5 min (1-in-20 fastest discovery, power cost: ~0 USD)
• Median expectation (50% Odds): Block within ~1.7 hours (Nominal median, power cost: ~0 USD)
• Bad luck streak (5% Odds): Can stretch up to ~7.3 hours (1-in-20 extended dry spell, power cost: ~0 USD)

High Variance Alert: In a 1-in-20 severe drought (~7.3 hours), cumulative electricity burned (~0 USD) will exceed the block reward value (0 USD). Pool mining is recommended for risk-averse operators.

GeForce RTX 4090 Price & Estimated ROI

Current market price: $1,450–$1,750 (estimated market price, median $1,600) (Hardware price estimated). Mined against its most profitable coin instead of solo, it would pay itself back in about 685 days.

How the odds have moved

BitcoinZ's network hashrate fell 10% since 2026-08-09, from 11.55 KH/s to 10.34 KH/s — so the same rig is now 10% more likely to find a block.

Where to point a GeForce RTX 4090 at BitcoinZ

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

• darkfibermines.com (Fee: 1% · Hashrate: 404.51 H/s)
• himpool.com (Fee: 2% · Hashrate: 160.76 H/s)
• aikapool.com (Fee: 0.5%)

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 99.99%, yearly chance 100.00%.

Frequently Asked Questions: GeForce RTX 4090 on BitcoinZ

Can you solo mine BitcoinZ with a GeForce RTX 4090?

Yes — a GeForce RTX 4090 (185.00 H/s) can solo mine BitcoinZ (BTCZ) via a solo pool. At BitcoinZ's 10.34 KH/s Zhash network that is about 3,596 blocks per year — expected one block roughly every 2.4 hours, for the full 3,125.0000 BTCZ block. BackPoW computes this from live network difficulty using a Poisson block-discovery model.

Is Zhash ASIC-resistant, and where does the GeForce RTX 4090 stand?

Zhash is an ASIC-resistant GPU algorithm relying on memory bandwidth. The GeForce RTX 4090 ranks #1 of 5 GPUs on BitcoinZ. It sits in the Commercial / High-Yield Tier (top quartile), making it highly competitive for steady pool income and realistic solo mining.

What is the operating power cost and breakeven electricity rate for a GeForce RTX 4090 on BitcoinZ?

At 250 W, operating a GeForce RTX 4090 consumes 6.00 kWh/day (182.6 kWh/month). At standard electricity (0.069 USD/kWh), the power bill is 0.41 USD/day (12.60 USD/month). The operational breakeven threshold is 0.113 USD/kWh.

What happens if my GeForce RTX 4090 encounters a severe dry spell on BitcoinZ?

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 7.3 hours, accumulating roughly 0 USD in power costs.
