At about 95 TH/s and the current network difficulty of 133.87T, the statistical mean time for a single Antminer S19 (used) to solve a block solo is:
“Avg” is the statistical mean — real luck swings wildly either way, which is the whole point of solo. The numbers move with the network; run your own on the odds calculator.
A Bitaxe is a lovely desk toy at ~1 TH/s. A secondhand Antminer S19 or S19j Pro does roughly 95-110 TH/s — call it a hundredfold more lottery tickets per second for a machine that, post-halving, can be found cheap on the secondhand market because it is no longer profitable for industrial farms. That gap is exactly why the used S19 is the sweet spot for hobbyist solo mining: it is the cheapest way to buy a genuinely meaningful amount of hashrate.
Be clear about what "meaningful" means, though. It moves you from astronomically unlikely to merely astronomically unlikely. More on that below — we would rather you buy one with open eyes than a fantasy.
A pool does not change your odds of solving a block — nobody's pool does. With true solo mining your chance of finding a block is set entirely by your hashrate versus the whole network. SoloLuck only changes the fee, the payout style (the whole block lands on your address), and the latency. That is it. Anyone promising "better luck" is selling you something.
At ~95 TH/s against a network in the hundreds of EH/s, a block is a statistically once-in-many-decades-to-centuries event for a single machine. A bigger ASIC shortens that, but not into anything you should plan your life around. Run the real numbers for your exact hashrate before you spend a rupiah on hardware:
Solo mining an S19 is a bet you make because you find the lottery itself fun and you can comfortably afford the power bill — not because it is an investment.
An S19 is a data-centre appliance. Running one in a house is entirely doable, but it is loud, hot, and thirsty, and the electricity bill — not the secondhand price — is the real cost.
| Reality | What to expect |
|---|---|
| Noise | ~75 dB at stock — vacuum-cleaner loud, continuously. Not a bedroom or living-room device. |
| Heat | ~3250 W is ~3250 W of heat dumped into the room. Wonderful in a cold climate, brutal in tropical SEA. |
| Power | ~3000-3500 W draw. Many units want a 240 V circuit and a beefy dedicated APW12-class PSU — check what the seller includes. |
| Bill | The dominant cost. ~3.25 kW × 24 h ≈ 78 kWh/day. Multiply by your tariff before buying. |
Common fixes: a shed, garage, or ventilated utility space; immersion or hydro kits for serious noise/heat control; or underclocking the firmware to trade some hashrate for far less noise and power. Underclocking also gently lengthens your odds — a fair trade if it keeps the peace at home.
SoloLuck splits its stratum by hardware class so each miner gets a sensible share difficulty. An S19 is high-hashrate iron and belongs on the Pro tier, port :4334 — the same tier used for Whatsminers and other large ASICs. Putting a 100 TH/s machine on a Nano or Lite port would flood the pool with low-difficulty shares for no benefit.
| Port | Tier | For |
|---|---|---|
| :3335 | Nano (diff 1) | NerdMiner / ESP32 |
| :3333 | Lite | Bitaxe |
| :8081 | Standard | Mid-range ASICs |
| :4334 | Pro | S19 / Whatsminer / high-hashrate |
| :3334 | TLS | Encrypted stratum |
SoloLuck is non-custodial: your Bitcoin address is your username, and if your machine solves a block the reward pays straight to that address on-chain from the coinbase. There are no accounts, no withdrawals, no balance for us to hold. Use a bc1 (bech32) address you control — ideally from a hardware wallet.
In the S19's web UI, open Miner Configuration → Pools and set Pool 1:
stratum+tcp://stratum.sololuck.io:4334 (or by IP, 148.230.98.87)bc1qyouraddress.s19 — your address, a dot, then any worker labelxAdd a second pool as backup if you like. That's the whole setup — there is nothing to register. Step-by-step screenshots live on the setup page.
On fees: SoloLuck takes 2% as a single coinbase output only on a block you actually find. If you never find one, you never pay anything — 0%. There are no ongoing or per-share fees.
SoloLuck's node is in Jakarta, roughly ~6 ms from much of Indonesia and SEA, versus ~250 ms to a typical US solo pool. Low latency won't manufacture luck, but it does mean your shares and any found block reach the pool and the network faster — fewer stale shares and a marginally better shot at your block not being orphaned. For a miner physically in Asia, that is a real, if modest, advantage. The site is available in 10 languages.
Now the honesty we promised: no block has been found on SoloLuck yet, and most of the hashrate you currently see on the pool is the operator's own rigs. We tell you this so you can judge the pool on its mechanics — true per-miner solo on ckpool -B, non-custodial payout, the Jakarta latency — and not on a track record that does not yet exist. Questions welcome on Telegram @SoloLuckPool.
Paste your address and copy the config from /setup, watch the pool on /status, and check every claim on /verify. Mine to your own address — that is what makes it truly solo.
