DEALS

Fast, no‑nonsense tools for home miners. We focus on clarity: copy‑paste inputs, human‑readable outputs, and presets for quiet devices. Start with the Solo Odds Calculator to understand lottery chances, then use the Profitability Calculator to plan costs. The Pool Latency & Fees table helps you pick a low‑latency, fair‑fee endpoint.

/tools/solo-chance-calculator/ — Solo Mining Odds Calculator

What this does: Given your hashrate, the network hashrate, and a time window, this calculator returns the probability of finding ≥1 block (your lottery odds). Works for BTC and any PoW chain if you enter the correct block interval (defaults to 600s for BTC‑like networks).

Inputs

  • Your hashrate (h) — e.g., 6 TH/s (accepts H/s, kH/s, MH/s, GH/s, TH/s, PH/s).
  • Network hashrate (H) — e.g., 936 EH/s.
  • Block interval (seconds) — default 600 for BTC/BCH/BSV/XEC; change for other chains.
  • Time window — choose hours/days/months/years (supports decimals).
  • (Optional) Number of devices — multiply hashrate to test combined rigs.

Outputs

  • P(≥1 block) over your time window (as %),
  • Expected time to 1 block (human‑readable),
  • “Feel‑for‑scale” comparison sentences.

Formula (transparent)

  • Expected blocks in time T:
    λ = (h / H) × (T / block_interval)
  • Probability of ≥1 block:
    P = 1 − exp(−λ)
  • Expected time to 1 block:
    E_time = block_interval × (H / h)

Device presets (editable)

  • Avalon Nano 3S → 6 TH/s, ~140 W (power used in Profitability tool).
  • NerdQaxe++ Rev6 → 6 TH/s, ~110 W.
  • NerdQaxe++ v4.8 → 4.8 TH/s, ~72 W.
  • Bitaxe Gamma → 1.2 TH/s, ~20 W (edit to your unit).
  • BMM101 → 1 TH/s, ~20–30 W (edit to your unit).
  • Jasminer X16‑Q (ETC) → 1,950 MH/s, ~620 W, block interval ~13.1s.
  • iPollo V1 Mini Classic (ETC) → 130 MH/s, ~104 W, block interval ~13.1s.
  • Goldshell Mini‑DOGE II (Scrypt) → enter your chosen LTC pool; Scrypt block interval (LTC) 150s.

Presets are starting points. Always measure your own unit and update values.

Examples

  • 6 TH/s on BTC (H = 936 EH/s), 365 days:
    λ ≈ (6e12 / 9.36e20) × (31,536,000 / 600) ≈ 0.000337 → P ≈ 0.0337%, expected time ≈ 2,968 years.
  • 6 TH/s on BSV (H = 0.332 EH/s), 1 year:
    λ ≈ (6e12 / 3.32e17) × (31,536,000 / 600) ≈ 0.953 → P ≈ 61.3%, expected time ≈ 1.05 years.

FAQ

  • Does adding more payout addresses help? No—only hashrate and time matter.
  • Why is my chance different from a friend’s? Network hashrate and time windows differ; odds scale linearly with both.

/tools/profitability-calculator/ — Mining Profitability Calculator (Home‑Friendly)

What this does: Estimates daily/monthly/yearly revenue and net profit for your device, with presets for quiet, home‑friendly miners. You can model pool fees, power cost, uptime, and coin price. For merged mining (e.g., LTC+DOGE), it supports multiple revenue streams.

Inputs

Device & power

  • Device name (free text or preset)
  • Hashrate (H/s, MH/s, GH/s, TH/s, etc.)
  • Power draw (W)
  • Uptime (%)
  • Electricity price (per kWh)

Network & price

  • Network hashrate (same units as device + suffix)
  • Block reward (subsidy + avg fees, in COIN)
  • Blocks per day (e.g., BTC ≈ 144, LTC ≈ 576, ETC ≈ 6,600/13.1s)
  • Pool fee (%)
  • Coin price (quote currency of your choice)
  • (Optional) Second revenue stream for merged mining (e.g., DOGE with LTC)

Outputs

  • Gross coins/day = (h / H) × blocks_per_day × reward
  • Gross revenue/day = gross_coins × price
  • Pool fee = gross_revenue × fee%
  • Power cost/day = (W × 24 / 1000) × price_per_kWh × uptime%
  • Net revenue/day = gross_revenue × (1 − fee%)
  • Net profit/day = net_revenue − power_cost
  • Autoscaled to per month and per year; includes break‑even kWh price.

Formulas (copy‑paste friendly)

  • Coins/day: = (h / H) * blocks_per_day * reward
  • Revenue/day: = coins_per_day * coin_price
  • Power/day ($): = (watts * 24 / 1000) * kWh_price * uptime
  • Net/day: = revenue_day * (1 - pool_fee) - power_day
  • Break‑even kWh price: = (revenue_day * (1 - pool_fee)) / (watts * 24 / 1000)

Presets (editable)

Prices, rewards, and fees change. Treat presets as templates and update inputs.

Examples

  • Avalon Nano 3S (6 TH/s, 140 W), BTC pool 2% fee, $0.20/kWh
    Let H = 936 EH/s, reward = 3.125 BTC + avg fees, price = $60k (example):
    coins/day ≈ (6e12/9.36e20) * 144 * 3.125 ≈ 2.88e-6 BTC
    revenue/day ≈ 2.88e-6 * 60000 ≈ $0.17
    power/day ≈ (140*24/1000)*0.20 ≈ $0.67
    net/day ≈ $0.17*(1-0.02) - $0.67 ≈ -$0.50 (illustrative; check live data)
  • Jasminer X16‑Q (1,950 MH/s, 620 W), $0.20/kWh — enter ETC metrics; outcome will vary widely with price/difficulty.

FAQ

  • Why do my results differ from a friend’s? Different power prices, fees, and live network data.
  • Can I model solar? Set kWh_price to your marginal cost during solar hours and run a split‑day scenario.

For editors (schema/SEO)

  • Schema: SoftwareApplication + HowTo + FAQ + BreadcrumbList.
  • Add a disclaimer block: prices/difficulty/fees change constantly.

/tools/pool-latency-fee-sheet/ — Pool Latency & Fees (Updated)

What this does: Provides a structured table to record fees, payout schemes, minimum payouts, and regional latency tests for popular pools across BTC, Scrypt, and ETC.

Why it matters

  • Higher latency/packet loss → more stale shares → lower effective revenue.
  • Transparent fees and payout schemes help you compare real returns, not just marketing.

Table schema

PoolAlgorithmRegions (URLs)FeePayout schemeMin payoutSSL?Notes
ExamplePoolBTCeu.pool:3333, us.pool:33332.0%FPPS0.001 BTCYesGood EU ping
ExampleScryptLTC/DOGEeu.scrypt:33332.5%PPLNS0.1 LTCYesMerged DOGE
ExampleETCETCeu.etc:55551.0%PPS+0.1 ETCYesStable

How to measure latency

  • Ping each hostname for 60–120s and note avg/95th percentile.
  • Run an MTR to spot jittery hops.
  • Prefer endpoints with <150 ms average ping from your location; ideally <80 ms.
  • Track stale share % in your miner dashboard (<1% is a good target).

Interpreting fees & payouts

  • PPS/FPPS = predictable payouts; PPLNS/PPBS = more variance but potentially slightly better returns.
  • Min payout too high? You’ll receive coins less often; adjust for your comfort.
