Ethereum Classic (ETC) Block Reward Reduction

In accordance with the Ethereum Classic Monetary Policy and the ETC emission schedule defined in ECIP-1017, the block reward dropped again in July. The reduction happens every 5,000,000 blocks and takes 20% off the reward each time. This one landed at block 25,000,001.

• Previous Reward: 2.048 ETC
• New Reward: 1.6384 ETC

Please pay attention! This is a 20% cut to what every ETC block pays out, and it applies to POOL and SOLO alike. We have already updated 2CryptoCalc with the new reward, so the numbers you see there are current.

Mining continues as usual on the ETC pool and ETC SOLO. No configuration changes are needed on your side.

Kaspa (KAS) Block Reward Reduction

As defined by the Kaspa Tokenomics, the Crescendo Hard Fork, and the official emission schedule, Kaspa underwent another scheduled block reward reduction in July.

• Previous Reward: 2.596 KAS
• New Reward: 2.449 KAS

Please pay attention! Kaspa mining profitability has changed. We have already updated 2CryptoCalc to reflect the new reward values. Mining continues on the KAS pool and KAS SOLO.

Zcash (ZEC) Ironwood Upgrade Activated

Last month we reported the emergency response to the Orchard soundness flaw. July closed that chapter. The Ironwood network upgrade — formally NU6.3 — activated on mainnet at block 3,428,143 on July 28, sealing the old Orchard pool and routing the shielded supply through a public accounting checkpoint known as the turnstile. The upgrade had been pushed back one week from July 21 specifically to give exchanges, wallets, and mining pools time to prepare.

Two things happened around it that matter to node operators:

• zcashd reached end of life on July 18. The reference client is done. Zebra is now the node to run.
• Zebra 6.2.3 shipped on July 28 as the Ironwood-ready release, built against the NU6.3 versions of the librustzcash libraries.

Our ZEC node runs Zebra 6.2.3 (commit 7121c82). Beyond Ironwood compatibility, the release is about network resilience: peers are no longer penalized for branch ID mismatches during the 40-block window around activation, the stall detector stops disconnecting peers near the chain tip, and outbound connection slots no longer clog with non-serving peers.

What it means for miners on 2Miners: nothing changes in your setup. Equihash mining and payouts ran normally through the activation. If you run your own node, migrate to Zebra — zcashd is no longer maintained. Mining continues on the ZEC pool and ZEC SOLO.

Node Updates

Nervos CKB — 0.208.0 and 0.209.0

Nervos shipped twice in July and we took both. Neither is a mandatory upgrade: all networks stay on the ckb2023 consensus version, and there are no protocol changes in either release.

0.208.0 (commit 585395c, July 14) is routine maintenance — the live cell RPC response now includes the block hash, plus dependency upgrades, a Windows runtime fix, and a rotation of the release signing key. Nothing mining-specific.

0.209.0 (commit d166e28, July 29) is the more useful one for anyone running their own node:

• Bearer-token authentication for miner notify mode — relevant to anyone running pool notification plumbing against their own node
• Tor support reimplemented directly, with better connection-loss detection
• Fixes for unbounded logger and relay-queue memory growth
• Transaction pool bug fixes

Eaglesong mining is unaffected. Mine on the CKB pool and CKB SOLO.

Pearl — 1.2.1

Our Pearl node is now on 1.2.1 (commit e72ad36), a maintenance release following the network’s move to v2 certificates in June. PearlHash mining is unchanged. Pearl runs on both PRL POOL and PRL SOLO, and profitability is on 2CryptoCalc.

SSL Certificates Renewed

We rotated the SSL certificates across all pools and restarted the stratum servers with the new certificates. If your miner logged a brief reconnect in July, this is the most likely reason. No action is required — mining resumed automatically, and connections using TLS stratum ports continue to work with no configuration change.

New Pool: Pearl (PRL)

We added a pool for Pearl (PRL), one of the more interesting launches of the year. Pearl is a GPU-mined coin with a twist: instead of wasted hashing, miners run real AI-style matrix math on Nvidia and AMD cards (proof-of-useful-work). It is already live on 2Miners — both POOL and SOLO.

• Algorithm: PearlHash
• Miner: SRBMiner-MULTI
• POOL: prl.2miners.com:1818
• SOLO: solo-prl.2miners.com:1919
• Password: x

Check profitability on 2CryptoCalc and start on the PRL pool or PRL SOLO. A full deep-dive guide on Pearl is coming soon.

Zcash (ZEC) Emergency Upgrade: Orchard Vulnerability Fixed

June brought the most important Zcash event in years. A soundness flaw was found in the Orchard shielded-pool proof circuit that could, in theory, be used to counterfeit ZEC inside the shielded pool. The privacy of existing funds and the 21M supply cap were not affected, and there is no evidence the flaw was ever exploited — but it required an immediate, coordinated fix.

Zcash developers, together with key network participants, responded in two phases:

• Soft fork (June 2) — temporarily rejected all Orchard transactions to freeze the risk.
• Hard fork NU6.2 (June 3) — re-enabled Orchard with a corrected circuit and a new verifying key. Node version 6.20.0 supports NU6.2.

What it means for miners on 2Miners:

• Our ZEC node is updated to 6.20.0 — a mandatory upgrade for anyone running a node.
• Equihash mining was unaffected and operated normally throughout.
• Payouts were suspended for a short time during the soft-fork window (shielded funds could not be moved) and have since resumed.
• No wallet or address changes are required.

The upgrade is complete and the network is being closely monitored. Mining continues on the ZEC pool and ZEC SOLO.

Node Updates

We also refreshed several coin nodes this month.

Beam — 7.5.14492 (HF6)

Beam shipped its sixth hard fork (“HF6”) as an emergency network upgrade. This is a node/consensus change — BeamHash III mining is unchanged, so your rigs keep working; only the node needs updating. We have updated our BEAM pool node to stay on the canonical chain.

Rusty Kaspa — v2.0.1

We updated our Kaspa node to Rusty Kaspa v2.0.1, the recommended release around the Toccata hard fork. Mining (kHeavyHash) is unaffected; the update improves node sync and operator tooling.

Ergo — 6.0.3

The release candidate we tested in May has shipped as stable 6.0.3. The most relevant change for miners: the node no longer tries to mine while it is still syncing, which avoids wasted, invalid candidates. It also fixes the mining-candidate cache for custom public keys and brings general sync and mempool improvements. Live on the ERG pool.

CKB — 0.207.0

A routine minor release with no consensus changes — maintenance and housekeeping only, with no action required from miners. Eaglesong mining is unchanged. Available on the CKB pool and CKB SOLO.

Kaspa (KAS) Block Reward Reduction

As defined by the Kaspa Tokenomics and its smooth monthly emission schedule, Kaspa underwent another scheduled block reward reduction in June.

• Previous Reward: 2.75 KAS
• New Reward: 2.596 KAS

Please pay attention! Kaspa mining profitability has changed. We have already updated 2CryptoCalc to reflect the new reward values. Mining is available on the KAS pool and KAS SOLO.

Neoxa (NEOX) and Cortex (CTXC) Delisting

We have discontinued pool and SOLO operation for Neoxa (NEOX) and Cortex (CTXC). The last payments for both coins have been processed.

If you were mining NEOX or CTXC, we recommend using 2CryptoCalc to find the most profitable coins for your hardware and point your rigs there.

New Guide: Home Bitcoin Mining in 2026

If you mine SHA-256 at home, take a look at our new guide on the best home miners and your real solo odds — Bitcoin versus Bitcoin Cash — and why the coin you point your miner at matters more than raw hashrate: Home Bitcoin Mining in 2026: Best Miners and Your Real Solo Odds.

Stay Updated

Follow us on X (Twitter) and join our Telegram chat to stay informed about new developments, miner alerts, and network upgrades.

The Home Mining Boom Has a Catch

A new generation of quiet, low-power SHA-256 miners has put solo mining back on the desk. A Bitaxe draws less power than a phone charger. A Canaan Avalon Nano is the size of a router and runs near library-quiet. You plug it in, point it at a pool, and you are mining the same algorithm as a warehouse full of Antminers.

The catch is scale. Your home miner does 1 to 15 TH/s. The Bitcoin network does close to 1 ZH/s — that is a billion TH/s. Solo mining is a lottery, and on Bitcoin the jackpot odds are astronomical. But SHA-256 is not only Bitcoin. Bitcoin Cash (BCH) uses the exact same algorithm, the same hardware, and the same block reward — on a network a few hundred times smaller. That one fact changes everything about home solo mining.

Which Home SHA-256 Miners Actually Make Sense

Three categories cover almost everything people run at home today. For a deeper breakdown of individual micro miners, see our Bitcoin solo mining guide.

Plug-in lottery miners (open-source)

• Bitaxe Gamma: a single BM1370 chip, around 1.2 TH/s at 15–18 W. Open-source, near-silent, the reference home miner.
• NerdQaxe++: four BM1370 chips, roughly 4.8–6 TH/s at about 100 W. The high end of the open-source boards.
• NerdMiner V2: an ESP32 learning device measured in kH/s, not TH/s. Treat it as an educational toy — its real-world block odds are effectively zero.

Commercial desktop miners

• Avalon Nano 3: 4 TH/s at 140 W. Pocket-sized, app-managed.
• Avalon Nano 3S: up to 6 TH/s, as quiet as 36 dB, with lower-power modes. The sweet spot for a quiet home unit.
• Avalon Mini 3 / Avalon Q: 37.5 TH/s and 90 TH/s respectively — a lot more hashrate while staying quiet (Avalon rates the Q at around 40–50 dB, close to a quiet office). The real trade-off is power and heat: at 800–1,674 W they warm a room far more than a pocket-sized Nano.
• FutureBit Apollo II: around 6 TH/s in eco mode and runs a full Bitcoin node alongside mining.

Repurposed datacenter ASICs

• Antminer S9: about 14 TH/s for very little money used, but roughly 1.3 kW and 75–85 dB of noise. Real hashrate, but loud and hot for a living space.
• Antminer S19 / S21: 90–235 TH/s. These are datacenter machines — the most hashrate per box, but not designed to live in a home.

Your Real Odds of Hitting a Block

Forget “thousands of years.” The honest way to picture solo mining is a lottery ticket: most tickets lose, but a single win pays an entire block — 3.125 BTC or 3.125 BCH. The only question is how good your ticket is, and that comes down to one ratio: your hashrate versus the whole network.

• Bitcoin network: close to 1 ZH/s — enormous, so the prize is huge and the odds are long.
• Bitcoin Cash network: about 3.5 EH/s, roughly 0.35% the size — so the same ticket is about 280–300× more likely to win.

Here is the chance of your miner finding a block in any given month, straight from 2CryptoCalc:

• Bitaxe Gamma (1 TH/s) — Bitcoin: ~1 in 204,000 · Bitcoin Cash: ~1 in 740
• NerdQaxe++ (4.8 TH/s) — Bitcoin: ~1 in 42,500 · Bitcoin Cash: ~1 in 154
• Avalon Nano 3S (6 TH/s) — Bitcoin: ~1 in 34,000 · Bitcoin Cash: ~1 in 123
• Antminer S9 (15 TH/s) — Bitcoin: ~1 in 13,600 · Bitcoin Cash: ~1 in 49

Put it in plain lottery terms. A single Bitaxe aimed at Bitcoin has roughly a 1 in 900 million chance on each block — true moonshot territory, but the prize is a whole 3.125 BTC. Aim that same Bitaxe at Bitcoin Cash and your odds climb to about 1 in 60 in a year. A quiet Avalon Nano 3S sits near 1 in 10 per year for a BCH block, and an Antminer S9 around 1 in 4. Those are real, human-scale odds — and a winning block pays the full 3.125 BCH even if it is nearly empty.

Want even better odds on the same SHA-256 hardware? Younger networks like Quai give a home miner a far bigger slice of the pie. See our guide to mining Quai on 2Miners.

Avalon Home Solo Mining in 3 Steps

Canaan’s Avalon Nano line is built for exactly this — managed entirely from the AvalonFamily app, no command line needed.

1. Power on and connect. Plug in the miner, open the AvalonFamily app, add the device, and connect it to your Wi-Fi.
2. Configure pool and wallet. Enter the solo mining pool URL, then your wallet address as the worker and x as the password.
3. Start mining. Save and refresh the dashboard. When the status reads Active and the hashrate climbs, you are mining.

One word of caution that Avalon’s own screen gives you: do not change advanced frequency or voltage settings unless you genuinely know what you are doing. Stock settings are tuned for stability, and a bad overclock costs you uptime — which on a lottery miner means fewer tickets, not more.

Settings for 2Miners Solo Pools

Bitcoin (BTC) SOLO

Full reward, paid to whoever solves the block. Use the closest region:

• Europe: solo-btc.2miners.com:2626
• USA: us-solo-btc.2miners.com:2626
• Asia: asia-solo-btc.2miners.com:2626
• Worker: your BTC wallet address
• Password: x

Pool page: 2Miners BTC SOLO.

Bitcoin Cash (BCH) SOLO

• Pool URL: stratum+tcp://solo-bch.2miners.com:9393
• Worker: your BCH wallet address
• Password: x

Two things to know about BCH on 2Miners. First, you can take your payout in BTC, TON, or BCH — useful if you would rather accumulate Bitcoin while mining the easier network. Second, if you are pasting an old legacy “1…” address from an exchange, convert it to the modern “bitcoincash:” format with the official Bitcoin Cash Address Converter first, or the pool will not credit you.

Pool pages: BCH SOLO and BCH PPLNS. For more on getting paid in a different coin than you mine, see BTC payouts for altcoin mining.

Solo or Shared: Where the Real Upside Is

Shared mining (PPLNS) pays you a steady trickle for the work you contribute — no luck involved. The problem at home is how small that trickle is. A Bitaxe mining Bitcoin in a shared pool earns on the order of 50 satoshis a day — a fraction of a cent. You will never feel it. That is not the pool’s fault; it is simply what 1 TH/s is worth against a zettahash network.

Solo flips the deal. Same miner, same power bill — but instead of dust every day, you hold a ticket on the entire block reward. Most days nothing happens. Then one block lands and you collect all 3.125 coins yourself. That is the whole point: shared pays you a little, guaranteed; solo pays you nothing, or a fortune. At home scale, where “a little” rounds to nothing anyway, the lottery shot is the rational fun.

This is exactly why Bitcoin Cash is the smart home target. Same miners, same 3.125 reward, but odds hundreds of times better — a genuine chance at a full block while you sleep, instead of a number with no zeroes in front of it. Run your exact miner through 2CryptoCalc to see both the shared payout and the solo probability for any hashrate, then pick your pool: BTC SOLO, BCH SOLO, or BCH shared.

Bitcoin Core 31.0: SOLO Pool Node Updated

We upgraded the node behind our BTC SOLO mining pool to Bitcoin Core 31.0, the latest major release. Block templates are now built on the new cluster-based mempool, and the release continues the migration of the mining interface to the multiprocess IPC architecture.

What changed:

• Cluster mempool. Transaction ordering was rebuilt around clusters, improving how block templates are assembled and how fee-bumping (RBF and CPFP) is evaluated.
• Mining interface (IPC). Block-template creation moved further toward the separate mining interface; coinbase data is now returned in structured form.
• Node performance. The default database cache was raised to 1024 MiB on machines with 4 GB+ of RAM, and the fee-estimation floor was lowered to 0.1 sat/vB.

Nothing changes for you as a SOLO miner — we run and maintain the node. Point your SHA-256 hardware at solo-btc.2miners.com:2626 with your Bitcoin address as the worker name. If your rig finds a block, the full reward (3.125 BTC plus fees) is yours.

Quai (QUAI) Node Update: go-quai v0.53.0 (BIP-302 Fork)

Quai activated the BIP-302 consensus fork with go-quai v0.53.0 on May 15, 2026. We updated our Quai nodes ahead of activation, so the QuaiKawPow and QuaiSHA pools stayed in sync through the fork.

Key changes for miners:

• Reward recalculation. The fork renormalizes Quai’s block reward against SHA-equivalent difficulty; KawPoW difficulty is now expressed in SHA terms.
• Short conversion freeze. A brief hold interval applied around the fork’s activation window.
• Stability fixes. Added a recovery step when Prime/Region/Zone headers are out of sync on restart.

Mining is available on the QuaiKawPow and QuaiSHA pools, with SOLO options for both.

Zcash (ZEC) Node Update: Version 6.12.3 — Security Hotfix

Zcash released v6.12.3, a security hotfix that we applied to our ZEC pool node immediately.

The release fixes CVE-2024-52911, a critical use-after-free vulnerability in block validation. Any inbound peer could trigger it by sending a crafted invalid block, crashing the node during script verification — and bouncing invalid blocks between peers could amplify a single crash into a network-wide outage. Every multi-core node running the default settings was affected on v6.12.2 and earlier.

If you run your own Zcash node, upgrade to 6.12.3 without delay. Our pool node is already patched.

Ergo (ERG) Node Update: Version 6.0.3-RC1

Ergo published 6.0.3-RC1, a release candidate focused on block propagation and mempool handling. We are testing it against our ERG pool node.

Notable changes:

• Faster block announcement. A new block is now announced to peers immediately, before full validation — this reduces propagation delay and helps lower stale/orphan rates for miners.
• Mempool improvements. Better handling of fee-based transaction replacement and a fix for duplicate transaction IDs.

As a release candidate, 6.0.3-RC1 is a pre-release; we will move our pool to the stable build once it ships.

Kaspa (KAS) Block Reward Reduction

As defined by the Kaspa Tokenomics and its smooth monthly emission schedule, Kaspa underwent another scheduled block reward reduction in May.

• Previous Reward: 2.914 KAS
• New Reward: 2.75 KAS

Please pay attention! Kaspa mining profitability has changed. We have already updated 2CryptoCalc to reflect the new reward values. Mining is available on the KAS pool and KAS SOLO.

Nexa (NEXA) Block Reward Reduction

In line with the Nexa tokenomics, the Nexa block reward was halved in May.

• Previous Reward: 10,000,000 NEXA
• New Reward: 5,000,000 NEXA

Please pay attention! Nexa mining rewards per block have been cut in half. We have updated 2CryptoCalc accordingly. Mining is available on the NEXA pool and NEXA SOLO.

Quai Network (QUAI) — New Mining Pools

2Miners launched mining pools for Quai Network on two algorithms: SHA-256 for ASIC miners and KawPow for GPU rigs. Both pool and solo are available across Europe, USA, and Asia. Full setup guide is in our Quai mining announcement.

• SHA-256 pool: 1% fee, 50 QUAI minimum payout, payouts every 2 hours
• SHA-256 solo: 1.5% fee, same payout terms
• KawPow pool: 1% fee, 50 QUAI minimum payout, payouts every 2 hours
• KawPow solo: 1.5% fee, same payout terms

Pool dashboards: QUAI SHA-256 and QUAI KawPow. Estimate profitability for your hardware on 2CryptoCalc.

Zcash (ZEC) Node Update: Version 6.12.1

We updated our Zcash node to zcashd v6.12.1, released on April 17. This is a security release fixing several vulnerabilities that could have caused nodes to crash, diverge from consensus with Zebra, or disable the defence-in-depth provided by pool turnstile checks.

The issues were reported privately by white-hat researcher Alex “Scalar” Sol and handled through coordinated disclosure by Shielded Labs, Zcash Open Development Lab (ZODL), and Zcash Foundation engineers, in coordination with mining pools.

Vulnerabilities addressed:

• An Orchard transaction with an rk encoding the identity point on the Pallas curve could cause zcashd to panic during proof verification. Fixed by rejecting identity rk before verification.
• The epk (ephemeral public key) in each Orchard action must encode a non-identity point. Zebra enforced this; zcashd did not — creating a potential consensus split. Now rejected.
• A duplicate block header could silently reset pool balance tracking fields, disabling ZIP 209 turnstile enforcement. Pool value initialization now happens after the duplicate-data check.
• The same bug could cause corrupted per-block pool deltas to be persisted to disk. The release adds a chain supply checkpoint at NU6.1 activation covering all value pools and recomputes shielded pool deltas from block data on startup.

Related changes also harden pool balance accumulation against signed integer overflow and improve exception safety around value computation. Mining on the ZEC pool and ZEC SOLO continues uninterrupted.

Kaspa (KAS) Block Reward Reduction

As defined by the Kaspa Tokenomics, the Crescendo Hard Fork, and the official emission schedule, Kaspa underwent another scheduled block reward reduction in April.

• Previous Reward: 3.086 KAS
• New Reward: 2.914 KAS

Please pay attention! Kaspa mining profitability has changed. We have already updated 2CryptoCalc to reflect the new reward values. Mining is available on the KAS pool and KAS SOLO.

Ergo (ERG) Block Reward Reduction

In line with the Ergo emission schedule defined by EIP-27, the network underwent a scheduled block reward reduction in April. Unlike Kaspa’s gradual monthly reductions, Ergo’s cuts happen in larger steps, and this one halved the reward.

• Previous Reward: 6 ERG
• New Reward: 3 ERG

Ergo mining profitability has dropped accordingly. Updated values are already reflected on 2CryptoCalc.

What Is Quai Network

Quai Network is a Proof-of-Work blockchain built around a new consensus mechanism called Proof of Entropy Minima (PoEM). It uses a hierarchical sharded structure — one Prime chain, three Region chains, and nine Zone chains — connected through merged mining, where a single hash secures the entire network. The architecture targets over 50,000 transactions per second across shards, with roughly 5-second block times per shard and around 30-second cross-shard settlement.

The network has a dual-token design. QUAI is the EVM-compatible token with a logarithmic, deflationary emission schedule similar to Bitcoin. Qi is a separate UTXO-based token with linear emission tied to mining difficulty. Miners can choose which token to earn — but on 2Miners, the pool currently mines and pays out QUAI.

Genesis supply is roughly 1.33 billion QUAI. The token is already trading on MEXC, Gate.io, LBank, and Kraken. Block explorer: quaiscan.io.

Quai Mining Algorithms

Quai is unusual: thanks to the SOAP upgrade, the network supports three Proof-of-Work algorithms — SHA256, Scrypt, and KawPow. All three secure the same chain through merged mining. 2Miners runs pools for two of them:

• SHA256 — for Bitcoin-style ASIC miners (Antminer S9 through S21, Whatsminer, Avalon).
• KawPow — for GPUs. The same algorithm previously used by Ravencoin, supported by all modern NVIDIA and AMD cards.

If you already mine BTC or BCH on SHA256 hardware, or have a Ravencoin-era GPU rig sitting idle, you can point it at Quai with no hardware changes — just a new pool address and wallet.

Quai Wallet Setup

Before connecting your miner, you need a Quai wallet address. There are three options:

• Pelagus Wallet — the official Quai browser extension (Chrome). Generates an address in under a minute. Recommended for most miners.
• Tangem — hardware wallet support for cold storage.
• Exchange deposit address — MEXC, Gate.io, LBank, or Kraken. Useful if you plan to sell or convert QUAI immediately. Make sure the exchange supports Quai mainnet deposits before pointing your miner at the address.

Quai addresses use the standard EVM hex format and start with 0x, for example: 0x004b0015A5a719765d2CeBF08dE8cfb965593F17. Keep your address handy — you will paste it as the worker name in your miner configuration.

Mine Quai with ASIC (SHA256)

Any SHA256 ASIC works. That covers the entire Bitmain Antminer S-series (S9, S11, S15, S17, S19, S21), Whatsminer M-series, Canaan Avalon, Innosilicon T-series, and any custom or refurbished SHA256 device. Firmware updates are not required.

Quai SHA256 Pool (PPLNS)

Use the PPLNS pool if you want regular, predictable payouts based on shares submitted. Fee: 1%. Minimum payout: 50 QUAI. Payouts run automatically every 2 hours.

• Europe: stratum+tcp://quaisha.2miners.com:8080

NiceHash port: 4949. SSL: 14848 and 14949. Pool page: 2miners.com/solo-quaikawpow-mining-pool.

PPLNS or SOLO: Which to Choose

The choice depends on your hashrate and risk tolerance.

• PPLNS pays you a steady share of every block the pool finds, proportional to the work your miner contributed. Predictable income, smaller variance, lower payout floor.
• SOLO pays you the full block reward — but only when your miner finds a block alone. Higher variance, potentially much larger payouts, no dilution.

If you have a single ASIC or one or two GPUs, PPLNS is the safer choice. If you run a serious operation, or want to take a deliberate shot at full block rewards, SOLO makes sense. Read more: Solo Mining Pools: How to Catch Your Luck.

Mining Profit Calculator Redesign: SHA-256, New Interface, and AI Integration

2CryptoCalc received its biggest update yet. The entire calculator has been rebuilt with a new interface and several major additions.

• SHA-256 support. Bitcoin (BTC) and Bitcoin Cash (BCH) mining calculations are now available — real-time price, network hashrate, block reward, and 24-hour profit estimates.

Bitcoin SOLO Mining on 2Miners: Pool Launched

We opened a BTC SOLO mining pool. Connect your SHA-256 hardware to solo-btc.2miners.com:2626, set the worker to your Bitcoin wallet address, and start mining.

This is a SOLO pool. If your miner finds a block, the full reward (3.125 BTC + transaction fees) goes directly to you. The pool provides the infrastructure — servers in Europe, US, and Asia with DDoS protection and low latency.

• Algorithm: SHA-256
• Pool Fee: 1.5%
• Minimum Payout: 0.05 BTC
• NiceHash: fully compatible

Cleaner Interface

The calculator has been rebuilt from the ground up with a simplified layout. The main page now organizes miners by manufacturer and algorithm, making it faster to find and compare devices. Hardware is grouped under four tabs: ASIC, NVIDIA, AMD, and Hashrate. You can add multiple devices, set quantities, and see profitability across all supported coins in one view.

SHA-256 Added: Bitcoin and Bitcoin Cash

The most significant addition is full SHA-256 support. 2CryptoCalc now covers Bitcoin (BTC) and Bitcoin Cash (BCH) alongside the existing lineup of ETC, KAS, ZEC, CKB, RVN, and GRIN. Both coins appear in the profitability table with real-time price, network hashrate, block reward, and 24-hour profit estimates.

The Hashrate tab lets you enter any SHA-256 hashrate directly to calculate expected earnings. Select 1,000 Antminer S21 units (SHA-256, 200 TH/s each) and the calculator instantly shows combined output across BCH and BTC pools, including solo mining probability for the selected period.

New ASIC Devices

The SHA-256 miner database now includes the full Bitmain Antminer S19 and S21 family: S19j XP, S19K Pro, S21, S21+, S21 Pro, S21 XP, S21 XP Hyd, S23, S23 Hyd, and T21. Each model includes its SHA-256 hashrate, power consumption, and profitability across BTC and BCH.

Non-SHA-256 device coverage has also expanded. New entries include additional IceRiver KAS miners, Goldshell models for CKB, and several iBeLink and Innosilicon units for Equihash. The full list is visible under the ASIC tab on the main calculator page.

Hashrate Calculator

The Hashrate tab works without selecting a specific device. Choose an algorithm, enter your hashrate in the relevant unit, and get the full coin comparison instantly. For example: entering 2,000 Mh/s on Etchash shows current ETC earnings with live network difficulty. The same tab covers SHA-256, Equihash, KHeavyHash (KAS), Eaglesong (CKB), KAWPOW (RVN), and all other supported algorithms.

MCP Server for AI Assistants

2CryptoCalc now provides an MCP (Model Context Protocol) server at https://2cryptocalc.com/mcp-for-ai. This lets AI assistants such as Claude and ChatGPT query live mining data directly, without manual lookups.

Once connected, an AI assistant can answer questions like “What is the most profitable SHA-256 ASIC right now?”, “How much can I earn mining ETC with an Antminer E9 Pro?”, or “Compare KAS vs ETC profitability for an IceRiver KS3.” Results include direct links to the relevant 2Miners pool pages.

The MCP server exposes seven tools:

• list_asics — all ASIC miners with hashrates, prices, and algorithms
• list_gpus — GPU list with hashrates, VRAM, and supported coins
• list_algorithms — all mining algorithms with default hashrate units
• calculate_asic_profitability — profit calculation for a specific ASIC model and quantity
• calculate_gpu_profitability — profit calculation for GPU models
• calculate_hashrate_profitability — profit by raw hashrate and algorithm
• get_coin_details — price, difficulty, block reward, and estimated earnings for any supported coin

Setup instructions for Claude Code, Claude Desktop, and the Claude API are on the MCP page.

Start Mining

All profitability results on 2CryptoCalc include direct links to the corresponding 2Miners pool. Use the calculator to find your best option, then connect your miner.

2Miners Bitcoin Solo Pool Is Now Live

Bitcoin needs no introduction. It is the first, most recognized, and most valuable cryptocurrency ever created. For years, miners have been asking us to add BTC. We finally did — but not as a regular PPLNS pool.

Want to skip straight to mining? Point your SHA-256 miner at solo-btc.2miners.com:2626 set the worker to your Bitcoin wallet address, password x — and you are already in the game. The full guide is below.

Here is the honest reason we did not launch a regular Bitcoin PPLNS pool earlier: in BTC mining specifically, competing with giants like Foundry, AntPool, and F2Pool requires enormous pooled hashrate — we are talking hundreds of exahashes. With other coins we regularly outperform much larger pools, but Bitcoin is a different scale entirely. Without critical mass, miners in a small PPLNS pool face unpredictably long waits between blocks, which is unfair to our users. Disappointing miners is something we never want to do — we always stand behind our pools and the people who use them.

SOLO changes the equation. In solo mining, your machine works independently. If it finds a block, the full reward goes directly to you — the pool only provides the infrastructure. No competition for pool share, no diluted payouts. Our job is to keep the servers fast and reliable. That we do perfectly.

We have been proving this across more than 10 years of running mining pools for dozens of coins. And specifically on SHA-256, we already have three years of experience with Bitcoin Cash — running both PPLNS and SOLO without issues. The BTC solo pool is built on the same codebase and the same server infrastructure.

If you want to understand how solo mining works compared to PPLNS, read our detailed guide: Solo Mining Pools: How to Catch Your Luck.

Who Is BTC Solo For?

The 2Miners BTC solo pool is for anyone mining Bitcoin on SHA-256 hardware — from a single old ASIC on a shelf to a full warehouse operation.

• Old ASICs still running. An Antminer S9 delivers around 14 TH/s. In a regular pool at today’s difficulty, that earns almost nothing after electricity. On a solo pool, every hash is a real chance at the full block reward. The cost of trying is just your electricity bill.
• Large operations going solo. If you have serious hashrate and want to keep 100% of every block you find, this pool is ready. Our servers handle high-load connections without issue.
• Micro miners. A new category of compact, low-power devices built specifically for home solo mining. See the section below.
• Hashrate renters. You do not need your own hardware. Services like NiceHash and MiningRigRentals let you rent SHA-256 hashrate by the hour and point it at any solo pool. Buy a few terahashes for an afternoon and take your shot. The pool supports both services natively — setup instructions are on the help page.

Micro Bitcoin Miners

A growing category of open-source, low-power Bitcoin ASIC devices has emerged for exactly this use case. They run SHA-256, connect over Wi-Fi, draw between 1W and 160W, and cost anywhere from $15 to $500. Most are available on AliExpress, Amazon, and dedicated retailers worldwide. These are real miners pointing at a real pool — not simulations.

NerdMiner V2

The NerdMiner V2 is an ESP32-based open-source device that costs around $15–30 on AliExpress. It runs the SHA-256 algorithm at roughly 55–300 KH/s depending on the version, drawing about 1–5W. It fits in your hand, makes no noise, and runs off a USB cable.

This is the most affordable entry into Bitcoin solo mining. The odds of finding a block are astronomically small — but the electricity cost is essentially zero, and the device doubles as a live Bitcoin network display on your desk.

Bitaxe Gamma 602

The Bitaxe Gamma is a proper open-source ASIC miner built around the BM1370 chip — the same chip used in the Bitmain Antminer S21 Pro. It delivers 1.1 TH/s at approximately 18W and costs around $77. Setup takes under five minutes via a browser-based interface called AxeOS.

This is not a toy. In November 2025, a cluster of six Bitaxe Gamma units found Bitcoin block #924,569 and earned 3.08 BTC — worth approximately $266,000 at the time.

NerdQaxe++

The NerdQaxe++ puts four BM1370 chips on a single board, delivering around 4.8 TH/s at approximately 35W. It is one of the most efficient devices in this category — similar hashrate to several old-generation ASICs, but in a quiet desktop form factor. Available from multiple open-source hardware retailers.

Canaan Avalon Nano 3S

The Canaan Avalon Nano 3S is a commercial compact miner with a built-in touchscreen, delivering around 6 TH/s. Unlike the open-source Bitaxe family, it comes fully assembled from Canaan — the same company that manufactures large industrial Bitcoin miners. A good option if you prefer a polished consumer product over open-source hardware.

Pool Details and Share Difficulty

The 2Miners BTC solo pool runs dedicated servers in three regions:

• Europe: solo-btc.2miners.com
• USA: us-solo-btc.2miners.com
• Asia: asia-solo-btc.2miners.com

Fee: 1.5% — among the lowest available for BTC solo mining.

Each region offers three share difficulty levels: 524K, 1M, and 16M. If you are unsure, use 524K. Use 16M if you are connecting via NiceHash or have very high hashrate.

An important note: share difficulty does not affect your rewards in any way. In solo mining, what matters is whether your miner finds a valid block — shares are just how the pool measures activity and plots your hashrate graph. A lower difficulty means more frequent share submissions and smoother statistics. A higher difficulty means each share takes longer to find but carries more weight. You can read the full explanation in our article: What is Share and Share Difficulty.

In practice, pick a difficulty level where your miner submits a share roughly every one to two minutes. This gives you a clean hashrate graph without unnecessary network traffic — useful if your connection is slow or unstable.

How to Start Mining Bitcoin Solo on 2Miners

Step 1 — Create a Bitcoin wallet. We recommend Bitcoin Core for desktop, or a hardware wallet — Ledger, Trezor, or Jade — for maximum security. If neither is an option, any mobile wallet works: Trust Wallet, Exodus, BlueWallet, or similar. You can also mine directly to any exchange address — obviously, every major exchange supports Bitcoin deposits.

The pool supports all Bitcoin address formats:

• SegWit (native bech32): bc1qnkyhslv83yyp0q0suxw0uj3lg9drgqq9c0auzc
• Compatibility (P2SH): 3GRdnTq18LyNveWa1gQJcgp8qEnzijv5vR
• Legacy: 1A1zP1eP5QGefi2DMPTfTL5SLmv7DivfNa

Step 2 — Configure your miner. Use the settings below. Replace YOUR_WALLET_ADDRESS with your actual address.

• Pool 1 (Europe): solo-btc.2miners.com:2626
• Pool 2 (USA): us-solo-btc.2miners.com:2626
• Pool 3 (Asia): asia-solo-btc.2miners.com:2626
• Worker: YOUR_WALLET_ADDRESS
• Password: x

For Bitaxe and NerdMiner devices, enter the same stratum address in the AxeOS web interface. Algorithm: SHA256. Full setup guide including SSL connections and NiceHash/MiningRigRentals configuration: solo-btc.2miners.com/help.

Step 3 — Check your stats. As soon as your miner submits its first share, your statistics will be available at solo-btc.2miners.com — just enter your wallet address. You can also monitor your workers in real time using the 2Miners mobile app: iOS and Android.

Calculate Your Odds

Use 2CryptoCalc to estimate your probability based on your hashrate and the current network difficulty.

An Antminer S9 at 14 TH/s has roughly a 1 in 1.273B chance of finding a block in any given month. Long odds — but a real number, not zero.

And it happens. Solo miners with a handful of terahashes have found blocks. The Bitaxe cluster example above is real. Every hash you submit is a valid lottery entry.

The prize is not just 3.125 BTC. Bitcoin miners also collect all transaction fees included in the block. At current network activity, a freshly mined block is typically worth $200,000 or more in total. That is the jackpot your miner is working toward, around the clock, for the cost of electricity.
