Solo Mine a (Used) Antminer S19 — or an S21 — on SoloLuck
Your live odds — Antminer S19 (used)
At about 95 TH/s and the current network difficulty of 127.48T, 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.
Why a used S19 is the 'serious' lottery ticket
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.
- S19 / S19 Pro: ~95-110 TH/s, ~3250 W (BM1398-class chips)
- S19j Pro: ~100-104 TH/s, similar power envelope
- All are far better solo tickets than any USB or ESP32 miner, and all belong on the Pro tier at SoloLuck
The honest odds (read this before you buy)
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.
The home realities nobody puts in the listing
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.
Which tier and port — use Pro (:4334)
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 (min diff 1) | NerdMiner / ESP32 |
| :3333 | Lite | Bitaxe |
| :8081 | Standard | Mid-range ASICs |
| :4334 | Pro | S19 / Whatsminer / high-hashrate |
| :3334 | TLS | Encrypted stratum |
Pointing the S19 at SoloLuck
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:
- URL:
stratum+tcp://stratum.sololuck.io:4334(or by IP,148.230.98.87) - Worker:
bc1qyouraddress.s19— your address, a dot, then any worker label - Password:
x
Add 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 nothing — a true 0%, finders keepers. A block you find pays its entire reward to your address in a single coinbase output, with no fee output skimmed, and there are no ongoing or per-share fees. How is it free? The operator mines here too and would rather grow the network than take a cut.
Bigger brother: solo an Antminer S21 too
The same setup works for an Antminer S21 — it just plays in a higher weight class. The S21 is Bitmain’s air-cooled workhorse: about 200 TH/s for roughly 3,500 W (≈3,550 W at the wall, ~17.5 J/TH), built on BM1368 chips rather than the S19’s older silicon — a bit over 2× the hashrate of a used S19, so a bit over 2× the lottery tickets in the exact same draw.
Point it the same way, on the Pro tier so it isn’t spammed with tiny shares: Stratum URL stratum+tcp://stratum.sololuck.io:4334, worker bc1youraddress.s21, password anything. Prefer encryption? stratum.sololuck.io:3334 is TLS at the Lite tier's starting difficulty — fine for a big machine, because vardiff quickly raises its difficulty automatically.
The home realities scale up too. ~3.5 kW continuous needs a dedicated 200–240 V circuit and a proper PSU/PDU — not a household power strip. Nearly all of it comes back as heat that will overwhelm a small room, and it runs at ~75 dB — a loud vacuum that never stops, so garage, shed or a sound-boxed space, not a bedroom. If noise is the deal-breaker, the water-cooled S21 Hydro (~335 TH/s) is quieter but needs a coolant loop and a dry cooler.
The odds, honestly: even at 200 TH/s a single S21 is a few ten-millionths of global hash, so on average it waits decades — often longer — between blocks. It could land tomorrow or never; that is what a lottery is. The live card above works the S19’s number; for the S21’s 200 TH/s the odds calculator runs the exact expected-time figure against today’s difficulty. Everything else on this page — the true 0% fee, a non-custodial payout straight to your address, and the SEA latency edge — applies identically.
The SEA latency edge — and full disclosure
SoloLuck's node is in Jakarta, roughly ~6 ms from much of Indonesia (measured 2026-07-03 from one Indonesian home-fibre line, median of spaced TCP connects — test yours at /ping), 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 Southeast Asia, that is a real, if modest, advantage.
Now the honesty we promised: no block has been found on SoloLuck yet, and it is still a small pool — though most of the hashrate you currently see now comes from community miners, not the operator. 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.

FAQ
Is a used S19 better than a Bitaxe for solo mining?
Yes, by roughly a hundredfold in raw hashrate — a used S19 is the one of the cheapest ways to buy a genuinely meaningful amount of hashrate secondhand (prices move — check current listings). But a block is still a once-in-many-decades-to-centuries event for one machine, so it is a better ticket, not a likely one. Run your exact numbers on the /guide/solo-mining-odds-calculator first.
Which port and tier should an S19 use on SoloLuck?
The Pro tier, port :4334 (stratum.sololuck.io, or 148.230.98.87). That tier is sized for high-hashrate ASICs like the S19, S19j Pro and Whatsminer. Don't use the Nano or Lite ports — they're for ESP32 and Bitaxe-class miners.
What does it actually cost to run an S19 at home?
The hardware is cheap secondhand; the electricity is the real cost. At ~3250 W that's roughly 78 kWh per day — multiply by your local tariff. Add ~75 dB of continuous noise, a lot of waste heat, and often a need for a 240 V circuit and a heavy APW12-class PSU. A shed, garage, or immersion/cooling setup is common.
How much does SoloLuck take, and where does the reward go?
A true 0% — finders keepers, with nothing taken from a block you find or any other day, and no per-share or ongoing fees. SoloLuck is non-custodial: your bc1 address is your username, and any block reward pays straight to that address on-chain. Use an address from a wallet you control.
Has SoloLuck found a block yet?
No, not yet — and we disclose that openly. The pool is still small, though most of its hashrate now comes from community miners rather than the operator. Solo odds are identical on every pool; what SoloLuck changes is the true 0% fee — finders keepers, nothing taken — the direct on-chain payout, and the ~6 ms Jakarta latency for SEA miners versus ~250 ms to US pools.
