Creating a bitcoin address for the Nerdminer V2, the NerdNOS and any solo miner: a 2026 guide

You have a Nerdminer V2 in your shopping cart or already on your desk — and somewhere between "plug in USB" and "find a block" comes that one step that most often raises questions for beginners: You need a Bitcoin address. Without it, your miner won't run, because the Stratum pool won't know where to send a potential block reward.

The good news: Getting a valid Bitcoin address is free and takes less than 10 minutes with a reputable provider. In this guide, we'll show you exactly which address format the Nerdminer V2 actually accepts, how to get one in a few steps, and how to correctly enter it into the miner. All technical specifications are directly aligned with the official NerdMiner_v2 documentation, the Bitcoin BIP-173 specification (Bech32), and the public pool data from mempool.space.

Why do you even need a Bitcoin address for the Nerdminer V2?

The Nerdminer V2 performs real Bitcoin Solo Mining via the public Stratum pool public-pool.io. If your device finds a valid block, the block reward (currently 3.125 BTC plus the transaction fees of all transactions included in the block) is transferred directly to the address you entered in the miner configuration in the so-called Coinbase transaction. Without this address, there would be no one to receive the reward — so the pool rejects the worker when connecting.

In short: The Bitcoin address is your mailbox for the potential reward. It must belong to you, not the seller, not the pool, no one else. The pool uses it as the Coinbase output target address in the block you might find, and the Bitcoin network irrevocably transfers the amount there once the block is confirmed.

What exactly is a Bitcoin address?

A Bitcoin address is a string of letters and numbers — similar to an IBAN, but with more characters and a built-in error check. Behind every address is a private key, which acts like a password: whoever has the private key controls all Bitcoin at the associated address. You can safely share the address itself — it's just the receiving address, not the key to the safe.

Important to understand: The Bitcoin address itself does not contain Bitcoin. It is just an "account marker" on the public blockchain. All payments to an address are publicly viewable — anyone can look up on mempool.space or another block explorer how much Bitcoin has flowed to a specific address.

Which address formats does the Nerdminer V2 support?

Bitcoin has introduced several address formats over the years — each with different properties, transaction efficiency, and varying compatibility. The Nerdminer V2 does not support all of them. The following overview shows which formats work:

Rule of thumb: Your Bitcoin address for the Nerdminer V2 should start with bc1q. This is Native SegWit (Bech32 according to BIP-173) — currently the most efficient address format for standard wallets. If you receive a Taproot address (bc1p...), the Nerdminer will not accept it. Most modern exchanges and wallets offer you a choice between formats when setting up — always choose Native SegWit if your target is the Nerdminer.

The three ways to get a Bitcoin address

There are roughly three options for obtaining a valid Bitcoin receiving address. Each has specific advantages and disadvantages:

1. Regulated crypto exchange — Easiest way for beginners. You register, verify your identity (KYC via video ID), and immediately get a receiving address that you can use in the Nerdminer. The exchange holds the Bitcoin for you (custodial).
2. Software wallet (Self-Custody) — You install a wallet app like BlueWallet, Sparrow, or Electrum. The app independently generates a private key that only you control. Full control, but also full responsibility for backups and securing the seed phrase.
3. Hardware wallet (Self-Custody, maximum security) — A physical device like BitBox02, Coldcard, or Trezor that stores the private key offline. Most secure, but costs €50–200.

Which option is right for you depends on how much security effort you want to put in and how important self-management is to you. For starting with the Nerdminer V2 — where realistic amounts are in the cents to low euro range, as long as no block comes — option 1 is the most beginner-friendly choice. We will now explain it using Finst as an example.

Option 1: Create a Bitcoin address with Finst — Step-by-step

Why Finst (and not Binance, Coinbase, or Bitpanda)?

Finst is a Dutch crypto exchange based in Amsterdam (Finst B.V.). Here are three specific reasons why we currently recommend Finst for Nerdminer beginners in the DACH region:

• MiCA License (AFM-regulated): Finst was one of the first platforms to receive a MiCA license from the Dutch financial supervisory authority AFM (license number 41000015). MiCA is the new EU regulation for crypto-asset service providers (Regulation 2023/1114) and applies uniformly across Europe. This means: strict consumer protection and transparency requirements that directly apply to DACH customers.
• 0.15% fee per trade: Significantly cheaper than most beginner brokers. For comparison: Coinbase Consumer charges 1.5–3%, Bitpanda 1.49%, Bitvavo 0.25%. For Nerdminer users who primarily only need a receiving address, the fees are even irrelevant — receiving Bitcoin (e.g., from a block find) is always free with reputable exchanges.
• Proof of Reserves: Finst is currently the first and only Dutch platform to have passed an independent Proof-of-Reserves verification by the audit firm Audit Now. This means: All customer funds are demonstrably available 1:1 and separated from company assets.

Alternatives in the DACH region: Bitvavo (NL, similar setup, but no independently audited PoR yet), Bitpanda (AT, higher fees, broader product portfolio), Coinbase (US, higher fees in the Consumer tier), Kraken (US, solid but more complex UI for beginners). From our perspective, Finst currently offers the best mix of low fees, strict EU regulation, and an easy-to-use beginner UX.

Step 1: Registration (approx. 3 minutes)

Open finst.com and click "Create account". You only need a working email address and a secure password (at least 12 characters, mix of upper and lower case letters, numbers and special characters). Then confirm your email via the link Finst sends you. After that, you'll be in the dashboard.

Step 2: Identity verification / KYC (approx. 5 minutes)

Due to the EU Anti-Money Laundering Directive (AMLD5) and the MiCA regulation, Finst must verify your identity before you can get started. This is done automatically via video identification directly in the browser or in the Finst app. You need:

• A valid ID card or passport
• A working camera (mobile phone or laptop)
• About 5 minutes for the entire process

After successful verification, your account is immediately active — you will receive a confirmation email and can directly use the deposit function.

Step 3: Generate Bitcoin receiving address (approx. 1 minute)

Now comes the part that this is all about. In the Finst dashboard:

1. Click on "Deposit" (or "Einzahlen", depending on the language version)
2. Select Bitcoin (BTC) from the list of cryptocurrencies
3. Finst will now show you your personal Bitcoin receiving address. It should start with bc1q and be about 42 characters long.
4. Click the copy button right next to the address
5. Save the address additionally in your password manager or a note app — this way you'll have it ready if you need to reconfigure your Nerdminer later

Important: Exchange receiving addresses can rotate with some providers — meaning Finst could theoretically show you a different address if you call "Deposit" again later. However, the old addresses still remain valid: Bitcoin sent to a previous address will still be credited to your Finst account. So you can leave the address you once received permanently in the Nerdminer.

Option 2: Self-Custody with a Software Wallet

If you prefer to maintain full control over your private key (keyword "Not your keys, not your coins"), self-custody is the way to go. For Nerdminer beginners, the following wallets are recommended:

• BlueWallet (iOS / Android) — Easy to use, available in German, natively supports Native SegWit. Open source, from a Spanish-American team.
• Sparrow Wallet (Desktop, Windows/macOS/Linux) — Slightly more advanced, but with built-in Tor integration and hardware wallet support. Very good transparency over every single transaction output.
• Electrum (Desktop) — The classic since 2011. Open source, very stable and fast, but with a less beginner-friendly UI.

Self-custody has two challenges you should be aware of: You need to write down and securely store a 12- or 24-word seed phrase (a typo or loss = Bitcoin gone forever), and you bear sole responsibility for backups. If your phone or laptop breaks and you haven't stored your seed in a second secure location, your Bitcoin will also be lost. For Nerdminer beginners with rather small realistic amounts, the exchange variant is therefore simpler. Self-custody is always possible as an upgrade later, once you have more experience.

Entering the Bitcoin address into the Nerdminer V2

You have your Bitcoin address in the clipboard. Now let's go into the Nerdminer:

Step 1: Connect Nerdminer to USB power source

Connect the Nerdminer V2 to your power supply, power bank, or laptop USB port using a USB-C data cable (not just a charging cable). The power LED will light up and the display will show the setup mode with a QR code after a few seconds.

Step 2: Connect to the setup Wi-Fi

The Nerdminer broadcasts a configuration Wi-Fi network named NerdMinerAP (or NerdMiner_xxxxxx depending on the firmware version). Connect your smartphone or laptop to this network. If a password is requested, use MineYourCoins. Most modern firmware versions (1.7.x and newer) automatically open the configuration page via a captive portal.

Step 3: Open configuration page in browser

If the page doesn't open automatically, enter 192.168.4.1 directly into your browser's address bar. You'll see the Nerdminer setup form with several fields — including SSID, Wi-Fi Password, BTC Address, Pool URL, and Pool Port.

Step 4: Paste Bitcoin address

In the "BTC Address" field (or "Bitcoin-Adresse"), paste your bc1q address received from Finst. Carefully check that no character is missing or extra. Bitcoin addresses have a built-in checksum (Bech32) — any incorrect letter will break the pool connection because the checksum no longer matches.

Step 5: Enter Wi-Fi data and Save

Enter your home Wi-Fi data (SSID + password) and leave Pool URL and Port at their default values: public-pool.io with port 21496. Then click "Save" or "Speichern". The Nerdminer will automatically restart, connect to your home Wi-Fi, and immediately start mining. On the OLED display, you will now see your live hashrate (typically 230–250 KH/s), the current Bitcoin block height, and the Stratum connection to the pool.

What happens if the Nerdminer finds a block?

Assuming your Nerdminer actually finds a block (statistically rare, but according to mempool.space data, it happens in documented solo pools every 2-3 weeks worldwide for some solo miner). Here's what happens in that order:

1. Block found — Your Nerdminer calculates a valid block hash and transmits it to public-pool.io.
2. Pool verifies and forwards — The pool checks the block for validity and sends it to the Bitcoin network. All Bitcoin nodes worldwide accept it.
3. Coinbase transaction — The new block contains a special first transaction (the Coinbase transaction) that transfers the block reward, currently 3.125 BTC plus the transaction fees of all transactions included in the block, to your configured Bitcoin address. Transaction fees can range from a few tenths of a BTC to several additional BTC depending on network congestion.
4. 100-Block Confirmation — Bitcoin protects Coinbase rewards with a built-in waiting period: 100 more blocks must be found after your found block before the reward can be spent. This takes approximately 16-17 hours. This rule is directly in the Bitcoin protocol and prevents issues with rare chain reorganizations.
5. Automatic credit — After 100 blocks, the amount is fully available. It will automatically appear in your account's Bitcoin wallet at Finst. You can hold it there, exchange it for another cryptocurrency, or transfer it to your bank account in Euros via SEPA payout.

So you don't have to actively collect anything — the entire process runs automatically once the block is confirmed on the network and reaches 100-block maturity.

Security Notes and Best Practices

Your Bitcoin address is NOT secret

Bitcoin receiving addresses are meant for receiving and can be shared publicly without hesitation. They contain no information about your private key. So you can safely show your Nerdminer address in screenshots, post it in forums, or share it on social media — this is not a security risk. (A privacy note on the side: Anyone who knows the address can see how many Bitcoins have flowed to that address on mempool.space. For absolute privacy, a new address is used for each reception — but this is not practical for the Nerdminer use case.)

The private key and seed phrase ARE secret

What you should never share are your private key, your seed phrase (12 or 24 words for software/hardware wallets), or your Finst password. Anyone who has one of these three things has full access to your Bitcoin. Finst or other reputable providers will never ask you for your password or seed phrase via email, phone, or chat. Any such request is a scam attempt (phishing).

Activate Two-Factor Authentication (2FA)

Activate two-factor authentication immediately after registering with Finst — preferably via an authenticator app (e.g., Aegis, Raivo, 1Password, Authy) and not via SMS. SMS 2FA is vulnerable to SIM swap attacks and is no longer recommended for crypto accounts.

Advanced: Self-Custody as an Upgrade

If you become familiar with mining and the Bitcoin world later and realize that you want to hold Bitcoin long-term, you can always switch to a self-custody solution. The change is as follows: (1) Set up a software or hardware wallet, (2) generate a new receiving address there, (3) reconfigure the Nerdminer and use the new address. Our guide to changing the Nerdminer configuration also covers changing the address.

Frequently Asked Questions

Do I absolutely need Finst, or can I use another exchange?

No, you can use any wallet or exchange that provides a Native SegWit receiving address (starts with bc1q). We recommend Finst for the reasons mentioned in the "Why Finst?" section (MiCA license, 0.15% fee, Proof of Reserves), but technically the Nerdminer V2 works with any compatible address.

Do I have to buy Bitcoin at Finst to use the address?

No. You receive the receiving address directly after KYC verification free of charge — whether you ever buy Bitcoin or not. So you can retrieve a valid Bitcoin address and enter it in the Nerdminer without spending a single Euro.

What does registration at Finst cost?

Registration and KYC are completely free. Fees are only incurred for active buying or selling of cryptocurrencies (0.15% per trade). Passive receipt of Bitcoin — for example, from a Nerdminer block find — is free of charge.

Can I connect multiple Nerdminers to the same Bitcoin address?

Yes, and it is even recommended. At public-pool.io, all workers with the same Bitcoin address are treated as a common mining session — your chance of finding a block accumulates across the individual devices. The display of many Nerdminer models also shows you the number of simultaneous workers and the cumulative total hash rate.

Will my Bitcoin block find be automatically sold?

No, at Finst, the amount remains in Bitcoin until you actively place an exchange order. You decide whether you want to hold the Bitcoin, exchange it for Euros, convert it to another cryptocurrency, or withdraw it to an external wallet.

Does the Nerdminer V2 support Lightning Network addresses?

No. The Nerdminer V2 mines on the Bitcoin base layer via the classic Stratum protocol pool public-pool.io. Lightning addresses (e.g., in the format name@lightning.address) or LNURL do not work — you absolutely need a classic on-chain Bitcoin address in the bc1q format.

Does Finst automatically accept Bitcoin from a Coinbase transaction?

Modern EU-regulated exchanges like Finst treat Coinbase outputs as normal Bitcoin deposits after the 100-block maturity period in the Bitcoin protocol — so the Bitcoin should be automatically credited to your account. We do not have written confirmation directly from Finst for this, nor can we test it in real-time (statistically rare event). If you want to be absolutely sure, contact Finst support beforehand with this specific question, or use a self-custody wallet where the private key is directly with you and Coinbase output acceptance is guaranteed.

How long does a Euro withdrawal take at Finst?

Once you have placed a sell order, the Euro amount is immediately available in your Finst account. The subsequent SEPA payout to your German, Austrian, or Swiss bank account usually takes 1–2 business days.

What if my address accidentally starts with bc1p?

That is a Taproot address (P2TR) — which is not supported by the Nerdminer V2. Solution: Create a new receiving address at Finst, in your software wallet, or in your hardware wallet and select Native SegWit (Bech32, bc1q) as the address type. Most wallets offer you this choice directly in the receive dialog or in the wallet settings.

Conclusion: Ready in under 10 minutes

The steps summarized again:

1. Create Finst account (3 min, free)
2. Complete KYC via video identification (5 min)
3. Retrieve Bitcoin receiving address in the deposit area (1 min) — must start with bc1q
4. Connect Nerdminer V2 to USB, open setup WLAN, paste address, enter WLAN data (1 min)
5. Save — the miner now runs 24/7 and actually mines on the Bitcoin network

That's all there is to it. Solo miners worldwide statistically find a block every 2–3 weeks (verifiable in public mempool.space data) — whether it's your Nerdminer ultimately depends on probability. Until then, you get live hash rate, block updates, and difficulty directly from the Bitcoin network on your OLED display. And if it happens, the full block reward of 3.125 BTC is yours — automatically transferred to the address you set up today.
