Solo mining: the variance nobody warns you about
Most mining pools run PPLNS or FPPS: every block the pool finds gets split proportionally between everyone who contributed shares. Your income is smooth and predictable. Solo mining flips that: the pool provides the stratum and block templates, but when a block is found, one miner gets the whole reward — everyone else gets nothing for that round.
The math in practice
On a small SHA-256 chain with, say, 3 TH/s of total network hashrate, a single Bitaxe at 1.7 TH/s controls more than half the network. That miner will find most blocks and solo mining is a no-brainer: paying a 1–2% pool fee on your own blocks makes no sense. Add a second 1 TH/s device and your odds rise accordingly.
Scale that up to a 100 TH/s network and the same Bitaxe now owns ~1.7% of the hashrate. At a 10-minute block time it finds a block roughly every 10 hours on average — but averages lie. Sometimes you'll find two blocks in an hour; sometimes you'll wait two days. That gap between average and reality is variance, and it's the entire price of solo.
When solo makes sense
- You mine a small community chain where your rig is a visible share of total hashrate. Check the network hashrate on the pool's stats page before connecting.
- The coin has a use or a community, so the reward is actually worth holding. Finding 3 BTC1 and having nowhere to spend them is emotional income only.
- You can tolerate dry spells. If you need mining to cover electricity tomorrow, smooth pool payouts are the safer tool.
- The pool charges 0% for solo. Many pools (ours included) take no fee on established coins, so solo costs you nothing but patience.
When a regular pool wins
If you mine a big coin (BTC itself, or a large fork), your rig is a rounding error of the network — a solo block would take years of luck. Pooled mining converts that lottery ticket into a trickle. FPPS even pays you the transaction-fee share, which on busy chains adds up.
How solo payouts actually work here
On MineCraft Pool each coin runs its own stratum ports tuned by hashrate class (small devices get low varDiff so shares register promptly). Blocks mature on the coin's chain, then the payout script sends the full block reward minus the network transaction fee to the wallet address you used as your worker name. Minimum payout thresholds exist only to batch tiny dust — for solo winners they rarely matter, because a block is one big payment.
One honest warning: solo "income" is lumpy. Track your luck over weeks, not hours, and treat a found block as a bonus event, not a salary.
FAQ
- Is solo mining profitable in 2026?
- On large coins, no — your chance of finding a block is negligible. On small SHA-256 community chains where a home ASIC is a few percent of network hashrate, solo can beat pooled mining because you keep 100% of the reward instead of 98–99% after fees.
- What happens if two miners find competing blocks?
- The chain keeps the block that the network builds on. If your block gets orphaned, the reward is lost — matured-but-orphaned blocks pay nothing. Good pools watch for this and surface it in stats.
- Do I need to register to solo mine?
- On this pool, no. Set your wallet address as the stratum username and point your miner at any port. The address is the account.
