How to Mine Cryptocurrency: Beginner’s Guide to Basics, Hardware, Software, Pools & Cashing Out
Crypto mining today is dominated by ASICs on PoW networks like Bitcoin. After the April 2024 halving, Bitcoin’s block reward is 3.125 BTC, with the network targeting ~144 blocks/day (≈ 450 BTC newly issued daily). Combined with a network hashrate measured in exahashes per second (EH/s), this explains why consumer PCs are no longer viable for BTC mining.
Most Bitcoin blocks are found by mining pools, so beginners connect hardware to a pool for steady, proportional payouts. Meanwhile, Ethereum is no longer mineable (moved to Proof-of-Stake in Sept 2022), so GPU/CPU miners focus on other PoW coins (e.g., Kaspa, Ravencoin, Monero).
In Europe, MiCA provides a single rulebook for exchanges and providers, shaping how pools, payouts, and cash-outs work (alongside local tax rules). This guide covers the basics, ASIC vs GPU vs CPU, software setup, pools vs solo, profitability math, selling payouts (SEPA/ACH), risks, and next steps — built for beginners in 2025.

TL;DR — Mining Basics for 2025
- Bitcoin mining = ASICs + cheap power; PCs won’t cut it.
- Pools give small, steady payouts; solo is “all or nothing.”
- EU cash-out: mine → self-custody → KYC exchange → SEPA/ACH.
- Profit math: electricity (€/kWh), efficiency, difficulty, price.
- If power is pricey (NL/DE retail), treat home mining as education, not profit.
Ultimate Guide: How to Mine Cryptocurrency (Beginner to Advanced)
Cryptocurrency mining secures decentralized networks and rewards miners for validating transactions. This guide walks you step by step — from basic definitions to advanced strategies, legality in Europe, hardware/software choices, profitability calculations, security, taxes, and future trends.
Mining 101 — Plain-English Primer (so a true beginner “gets it”)
What does “mining” mean?
On a PoW blockchain (like Bitcoin), thousands of computers compete to solve a math puzzle. The first to solve it creates a new block (a bundle of transactions) and is paid a reward. That payment is how new coins enter the system and why miners participate.
What does “3.125 BTC per block” actually mean?
Every time a new block is created on Bitcoin, the winning miner gets a fixed reward of 3.125 BTC (plus transaction fees). One BTC can be split into 100,000,000 tiny units called satoshis (sats), so 3.125 BTC = 312,500,000 sats. This fixed reward used to be higher and is cut in half about every four years — a scheduled event called the halving.
What does “≈144 blocks per day” mean?
Bitcoin aims for one block every ~10 minutes. In a 24-hour day, that’s roughly 144 blocks. At 3.125 BTC per block, the network issues about 450 BTC/day (3.125 × 144). Per year that’s ≈ 164,250 BTC. Compared to the 21 million max supply, that is < 1% new supply per year today.
Why this matters: fewer new coins entering the market (especially after halvings) can tighten supply. For miners, a lower reward means you must be more efficient (cheaper power, better machines) to stay profitable.
What is “hashrate” and why can’t a normal PC mine Bitcoin now?
A hash is one “lottery ticket” guess at the puzzle. Hashrate is how many guesses your machine makes each second. The whole network’s hashrate is enormous (measured in exahashes per second, EH/s). A normal PC might do tens of millions of hashes per second (MH/s) — that’s like bringing a water pistol to a firefight where everyone else has fire hoses.
Specialized machines called ASICs are millions of times faster and more energy-efficient than PCs. That’s why Bitcoin mining today is ASIC-only in practice.
What is a mining pool (and why beginners use one)?
If you mine alone (solo mining), you either win a whole block reward (rare) or nothing. A mining pool groups thousands of miners together and splits rewards by each person’s contribution. Result: small, steady payouts instead of “all-or-nothing.” Pools usually charge a small fee (≈1–2%).
Where do miner earnings come from exactly?
Two sources:
- Block reward — currently 3.125 BTC on Bitcoin (halves every ~4 years).
- Transaction fees — users pay fees to get included in the block; this amount varies daily.
On some days, fees are small; on busy days, fees can be a big chunk of miner income.
Energy & costs — the part most beginners miss
Mining converts electricity → heat + lottery tickets (hashes). Your profit depends mainly on:
- Your electricity price (€/kWh): lower is better.
- Your machine’s efficiency (hashes per watt): newer ASICs win.
- Competition (network hashrate/difficulty): more competitors → harder to earn.
- Coin price: if price falls but your power bill doesn’t, profits disappear fast.
Simple picture: Imagine 450 BTC is baked each day and shared by everyone, proportional to their hashrate. If you contribute only a microscopic slice of the total, your share of that 450 is also microscopic — sometimes worth less than your power bill.
“Can I mine Ethereum?” (No — it’s Proof-of-Stake now)
Ethereum switched from PoW to PoS in 2022 (the “Merge”). That means no more Ethereum mining. Some other coins still use PoW (e.g., Monero is CPU-friendly; Kaspa, Ravencoin, Flux are GPU-mineable), but profitability varies and can be negative with high electricity prices.
What’s MiCA (EU rules) and why should I care?
MiCA is the EU’s rulebook for crypto service providers (exchanges, custodians, etc.). It doesn’t tell you how to plug in a miner, but it affects your payouts and cash-outs: exchanges and some services will expect KYC, proper records, and may flag suspicious activity. In short: you can mine coins, but to cash out to a bank you must follow compliance.
Risks, Challenges & Considerations
Mining looks simple—plug in, get coins—but real outcomes depend on costs, reliability, and security. Use this checklist before you spend money.
- Electricity cost: High kWh rates erase profit fast. At typical NL/DE retail prices, most setups run negative.
- Hardware depreciation: ASICs and GPUs lose value as newer, more efficient models launch.
- Volatility: Coin prices can drop 50%+; “profitable” today can be loss-making tomorrow.
- Difficulty & luck: Network difficulty rises with competition; pool luck and payout method (PPS/PPLNS/FPPS) change income.
- Downtime & maintenance: Heat, dust, and fan failures reduce uptime and earnings.
- Noise & heat: ASICs are loud and hot; you may need ventilation or sound isolation.
- Regulation & taxes: KYC/AML checks at off-ramps; mining income is usually taxable. Keep clean records.
- Counterparty risk: Pools, exchanges, hosting providers, and “cloud mining” platforms can fail or be hacked.
- Security: Self-custody safely; never share seed phrases; avoid remote-access tools on wallets/miners.
- Cash-out frictions: Bank name must match exchange; AML reviews can delay SEPA/ACH withdrawals.
- Opportunity cost: In high-cost regions, buying and holding BTC often beats home mining.
Example: Is Solana (SOL) or Kusama (KSM) a “better investment”?
Short answer: “Better” depends on your thesis, time-horizon, and risk tolerance. Use this as a risk lens—not a tip.
- Solana (SOL) — Layer-1 high-throughput chain
-
Pros: Large builder/user base; fast; deep liquidity.
Risks: Complexity, possible network incidents, smart-contract/bridge risk, ecosystem concentration. - Kusama (KSM) — Polkadot’s canary/experimental network
-
Pros: Rapid upgrades; experimental features for builders.
Risks: Explicitly experimental; governance/change risk; thinner liquidity; potential dilution from issuance.
Risk checklist for any coin: Understand use case, tokenomics (issuance/unlocks), governance, worst drawdowns, custody plan, and your exit plan.
Mitigations (quick wins)
- Measure wall-power with a smart plug; time-box tests (1–3 hours) before committing.
- Tune for efficiency (undervolt/underclock) instead of chasing max hashrate.
- Start with reputable pools; test small payouts to self-custody first.
- Keep monthly logs: payouts, kWh, pool statements, invoices for tax.
- Set a sell/hold policy (e.g., sell to cover power, hold the rest).
- Avoid “cloud mining” promises; if you experiment, keep it €10–€20 only.
Bottom line: In NL/DE retail power, mining for profit is usually a losing game. Treat home mining as education unless you have cheap power, heat-reuse, or hosted ASICs in low-cost regions.
Which Mining Hardware Is Best in 2025? (ASIC vs GPU vs CPU)
Your hardware determines profitability, power use, and which coins you can mine.
- ASIC (Application-Specific Integrated Circuit)
- Most efficient for Bitcoin and large proof-of-work coins. Expensive, loud, energy-hungry.
- GPU Mining
- More flexible — can mine various altcoins. Hardware widely available. Higher energy cost per unit hash.
- CPU Mining
- Entry-level, only profitable on certain niche coins. Often used for experimentation or education.
SEO Tip: Include comparisons like “best ASIC for Bitcoin mining 2025” or “GPU vs ASIC mining”.
Mining Software & Setup
Software connects your hardware to the blockchain or mining pool.
- Bitcoin Core (full node mining, not typical for solo miners).
- CGMiner and BFGMiner (popular for ASICs).
- NiceHash (marketplace for buying/selling hashrate).
- Ethash / KawPow miners (for GPU-mineable altcoins).
Configure wallet addresses, pool connections, and system monitoring before running.
Solo Mining vs Pool Mining
Solo mining means competing directly with the network. Pools allow miners to combine power and share rewards.
- Solo Mining
- Unlikely to succeed unless you control massive hashrate.
- Mining Pool
- Steadier, proportional payouts. Pool fees usually 1–2%.
Beginner tip: Always start with a pool to smooth payouts.
Is Crypto Mining Legal in the EU?
In general, proof-of-work mining is permitted in many EU countries, but it must comply with local laws (energy usage, consumer protection, zoning, noise, environmental standards). Income is typically taxable, and selling mined coins may trigger reporting.
Netherlands (NL)
Mining is generally allowed when you follow local regulations and contracts with your energy provider. Expect standard tax obligations on mining income and disposals. Always verify current guidance before operating.
Germany (DE)
Mining is generally permitted, subject to compliance with local regulations (including electricity contracts and any building rules). Tax treatment depends on activity and holding period; confirm details before you begin.
Important: Regulations and tax guidance evolve. Check current official sources in your country before mining or selling.
How Do You Cash Out Mined Crypto? (SEPA/ACH/SWIFT)
Move payouts to a self-custody wallet first, then send to a reputable exchange to sell or swap. Expect to complete KYC/verification before cashing out.
- Withdrawal rails: SEPA (EU), ACH (US), FPS (UK); where unavailable, SWIFT international wires are used.
- Security tip: Don’t mine directly into an exchange wallet. Enable 2FA; consider address whitelisting.
- Name matching: Your bank account name should match your exchange profile to avoid delays/returns.
- Record-keeping: Keep logs of mining income, fees, txids, sale proceeds, and withdrawals for tax reporting.
Beginner-to-Pro Checklist
- Learn what mining is and how it works.
- Check legality in your country (tax + energy rules).
- Calculate profitability with real hardware + electricity cost.
- Start with a reputable mining pool.
- Use self-custody wallets for payouts.
- Keep tax-compliant logs from day one.
- Diversify into staking/alternatives if mining becomes unprofitable.
FAQ: Crypto Mining (2025)
Is crypto mining legal in the EU (especially the Netherlands & Germany)?
Generally yes. Mining is permitted in most EU countries, including NL and DE, provided you follow local energy contracts, zoning/noise rules, and tax/reporting. There’s no EU-wide mining ban; profitability (power price) is the real barrier.
Can I mine Bitcoin with a normal PC?
Technically yes, but practically no. Bitcoin mining is dominated by ASICs (specialized machines). A consumer CPU/GPU only contributes a microscopic share of the network hashrate, so even in a pool your payout would be far below your electricity cost.
- Why: A PC does ~tens–hundreds of MH/s, while the Bitcoin network is in the hundreds of EH/s → your share is effectively zero.
- Result: Fractions of a cent per day in rewards vs. euros per day in power.
What to do instead: If you want BTC exposure, buy and self-custody it. If you want to learn mining, try a CPU-friendly coin (e.g., Monero) for a short educational run or rent a tiny amount of hashrate for testing—not profit.
ASIC vs GPU vs CPU — which is best in 2025?
ASIC (best for BTC): highest efficiency, needs cheap power. GPU (altcoins): flexible but power-hungry. CPU (niche coins): OK for learning; rarely profitable at EU power prices.
What software do I need to start?
For ASICs: CGMiner/BFGMiner or pool web UIs. For GPUs/CPUs: coin-specific miners (e.g., XMRig for Monero). You’ll also need a self-custody wallet and a pool account.
Should I mine solo or join a pool?
Join a pool. Solo mining is “all or nothing.” Pools pay steady, proportional rewards based on your submitted shares.
How long does it take to earn 1 BTC?
It depends on your share of the network. Bitcoin issues ~450 BTC/day (3.125 BTC × ~144 blocks). With one ~200 TH/s ASIC at today’s competition, expect only tiny daily fractions—years to decades for 1 BTC unless you scale to many units.
How do I calculate profitability?
Use a mining calculator with your hashrate, power draw (watts), electricity price (€/kWh), pool fee, and coin price. Recheck often—difficulty and prices change.
How do I withdraw payouts to my bank (SEPA/ACH)?
Mine to a self-custody wallet first, then send to a regulated exchange. After KYC, withdraw via local rails (SEPA in EU, ACH in US). Keep records (income, fees, txids) for taxes.
Is renting hashpower (e.g., NiceHash) risky?
Yes. Profitability can swing; many “cloud mining” sites are scams. If you try it, use only established marketplaces, keep budgets tiny, and treat it as learning—not investing.
What are the safest first steps today?
Create a self-custody wallet; test a pool for 1–3 hours or rent a very small amount of hashpower; measure wall power; log payouts and costs. If power ≥ €0.15/kWh, consider buying and holding BTC instead of mining.
I Received Bitcoin/Ethereum from a Random Address — Is It a Scam? What Should I Do?
Short answer: Treat unexpected crypto in your wallet or exchange account as suspicious. It can be a dusting attack, address-poisoning, fake airdrop, or an attempt to use you as a money mule. Don’t move it, don’t “return” it, and don’t connect to unknown sites.
Why this happens
- Dusting attack: Scammers send tiny amounts to link your addresses when you later spend that “dust.”
- Address poisoning: You’re sent tokens from a look-alike address so you later copy the wrong address and send funds to the scammer.
- Fake airdrop / approval phishing (ETH & tokens): You see new tokens; interacting or “claiming” asks you to sign approvals that let scammers drain your wallet.
- Money-mule risk: Large “random” deposits can be stolen/tainted funds. If you forward them, you can trigger AML flags or legal trouble.
What to do (safe checklist)
- Do nothing first: Don’t try to move or “refund” the coins. Never share your seed phrase. Ignore any DMs/emails claiming to be “support.”
- Verify on a block explorer: Confirm the transaction is real (on-chain) and the asset is genuine (many tokens are spoofed).
- Separate your funds: Create a fresh wallet (new seed). Move your own existing, clean funds there. Leave the suspicious assets behind.
- Use coin control (Bitcoin): When spending, select only your known UTXOs; do not spend the suspicious UTXO.
- Revoke approvals (Ethereum): If you interacted with unknown dApps, use a trusted approval-revoker tool to remove token allowances from your old wallet.
- Exchange accounts: If an exchange account shows an unknown deposit, don’t withdraw. Contact exchange support; they have AML obligations.
- Big amounts / legal risk: If the amount is significant or you’re contacted about forwarding it, don’t touch it. Keep records (txids, timestamps, messages) and consider speaking with a qualified lawyer or your local cybercrime unit.
Red flags (ignore these)
- “Return a portion to unlock the rest” or pay a “release fee.”
- Sites asking you to connect your wallet to “verify ownership” of the deposit.
- Requests for remote access or your seed phrase/private keys.
Bottom line: An unexpected crypto deposit is almost never free money. Treat it as toxic: isolate it, protect your real funds in a new wallet, and avoid any interaction that could authorize a drain or create AML trouble.
Conclusion — Your First Safe Steps
Bitcoin mining today is an efficiency game: ASICs + cheap power + disciplined ops. For most beginners at EU retail power, home mining is best treated as education, not profit. Start tiny, measure everything, and keep clean records. If your goal is BTC exposure, buy and self-custody may beat mining until you access cheap power or hosted ASICs.
