What is Bitcoin Mining?
The foundation of the Bitcoin network
Bitcoin mining is the computational process that secures the Bitcoin network and processes transactions. Miners use specialized computers called ASIC miners to solve complex mathematical puzzles. When a miner successfully solves a puzzle, they earn the right to add a new "block" of transactions to the blockchain and receive newly minted bitcoin as a reward.
Think of Bitcoin mining as a global lottery that runs every 10 minutes. Thousands of miners around the world compete to find the winning number. The first one to find it gets to add the next page (block) to Bitcoin's ledger (blockchain) and collects the prize—currently 3.125 BTC per block (worth approximately $300,000 at $96,000/BTC) plus transaction fees.
Unlike traditional currencies controlled by central banks, Bitcoin has no central authority. Mining is the decentralized mechanism that:
- Validates transactions — Ensures every Bitcoin transaction is legitimate and prevents double-spending
- Secures the network — Makes it virtually impossible to alter past transactions due to massive computational requirements
- Issues new Bitcoin — Distributes new coins to miners who contribute computational power to the network
Key Terminology
- Hashrate (TH/s)
- Trillions of calculations per second. A measure of mining power. Higher hashrate = more chances to solve the puzzle.
- Block Reward
- The amount of Bitcoin awarded for mining a block. Currently 3.125 BTC (after the April 2024 halving).
- Difficulty
- How hard it is to mine a block. Adjusts every 2 weeks to maintain ~10 minute block times. Currently ~144 trillion.
- Mining Pool
- A group of miners who combine their computing power and split rewards proportionally. Essential for individual miners.
Why Mining Matters
The backbone of Bitcoin's security and decentralization
Mining isn't just about earning Bitcoin—it's what makes Bitcoin revolutionary. Here's why it matters:
Decentralization
Mining distributes power across thousands of independent operators worldwide. No single entity controls Bitcoin—making it censorship-resistant and truly permissionless.
Immutability
The computational cost of mining makes rewriting history astronomically expensive. To alter one old transaction, you'd need to re-mine every block since—requiring more energy than entire countries consume.
Fair Distribution
Unlike traditional currencies printed by governments, Bitcoin is distributed to those who contribute computational resources. Anyone can participate—no permission needed.
Predictable Supply
Mining enforces Bitcoin's 21 million coin cap. The block reward halves every 4 years, creating a deflationary supply schedule that's programmatically guaranteed—no central bank can change it.
For miners specifically: Mining offers a way to earn Bitcoin at production cost rather than market price. When done efficiently with low electricity costs, mining can be more profitable than simply buying Bitcoin—especially during bear markets when prices are suppressed but difficulty is lower.
How Proof of Work Works
A simple explanation of Bitcoin's consensus mechanism
Bitcoin uses a consensus mechanism called Proof of Work (PoW). Here's how it works in plain English:
The Mining Process (Step-by-Step)
- 1
Transaction Collection
Miners collect pending transactions from the mempool (waiting area) and bundle them into a candidate block—like gathering letters to put in an envelope.
- 2
Puzzle Solving (Hashing)
Miners try to find a special number (called a "nonce") that, when combined with the block data and run through SHA-256 (a cryptographic hash function), produces a result starting with a certain number of zeros. This is the "puzzle."
- 3
Trillions of Guesses
There's no shortcut—miners must try random nonces until one works. A modern ASIC miner makes ~200 trillion guesses per second. The entire network makes over 1,000,000,000 trillion (1 zettahash) per second combined.
- 4
Broadcasting the Solution
When a miner finds a valid nonce, they broadcast the block to the network. Other nodes verify it's correct (takes milliseconds) and add it to their copy of the blockchain.
- 5
Reward Collection
The winning miner receives 3.125 BTC (block subsidy) plus all transaction fees from that block—typically 0.1-0.5 BTC extra. The entire process then repeats for the next block.
Why "Difficulty" Matters
Every 2,016 blocks (~2 weeks), Bitcoin automatically adjusts the difficulty to maintain an average 10-minute block time:
- • More miners join → difficulty increases → puzzles get harder
- • Miners leave → difficulty decreases → puzzles get easier
Current difficulty: ~144 trillion (as of Feb 2026). This is the highest it's ever been, reflecting intense competition and network security.
The beauty of Proof of Work: It ties Bitcoin's security to real-world energy expenditure. Attacking the network requires outspending all honest miners—an economic impossibility at current scale.
Home Mining vs Hosted Mining
Understanding your setup options
One of the first decisions you'll make is where to run your miners. Each approach has distinct trade-offs:
Home Mining
Pros
- Full control and ownership
- No hosting fees
- Educational experience
- Can use waste heat for heating
Cons
- Extreme noise: 75-80+ dB (vacuum cleaner level) 24/7
- Massive heat: 12,000+ BTU/hr per miner
- Electrical upgrades: Requires 220V, often $500-3,000+
- High electricity costs: Residential rates typically $0.12-0.20/kWh
- Fire hazards: Continuous high-load electrical draw
- Dust and maintenance burden
- Downtime during troubleshooting
Hosted Mining
Pros
- Industrial electricity: $0.03-0.07/kWh (vs $0.12-0.20 home)
- Professional infrastructure: Optimized cooling, reliable power
- 99.9% uptime: 24/7 monitoring and rapid repairs
- Zero noise/heat at home
- Scalable: Add 10 miners as easily as 1
- Expert support and firmware management
- Tax-deductible hosting fees
Cons
- Monthly hosting fee ($30-75/miner typical)
- Trust required in hosting provider
- Less "hands-on" experience
The Math: Why Hosting Usually Wins
Let's compare the same miner (Antminer S21 - 200 TH/s, 3500W) in both scenarios:
Home Mining
Hosted Mining
Result: Hosted mining earns $164/month more (~3.9Ă— higher profit) despite the hosting fee. The industrial electricity rate makes the difference.
Our recommendation: Unless you have industrial electricity rates at home, access to free cooling, and high noise tolerance, hosted mining is almost always the better choice for profitability and convenience.
What You Need to Get Started
The essential checklist for new miners
Starting your mining journey requires a few key components. Here's everything you need:
Bitcoin Wallet
You need a Bitcoin address to receive mining payouts. Choose based on your security needs:
- Hardware Wallet (Recommended): Ledger, Trezor, Coldcard — Most secure for serious miners
- Software Wallet: Sparrow, Electrum, Blue Wallet — Good balance of security and convenience
- Exchange Wallet: Coinbase, Kraken — Convenient but less secure (not your keys, not your coins)
ASIC Miner
The specialized hardware that does the actual mining. See our Hardware Guide for detailed comparisons, but here's a quick overview:
Budget-Friendly
Older generation miners
S19 series, M30S series: $800-2,000. Lower efficiency but affordable entry.
Current Generation
Latest tech, best efficiency
S21, M60, A15 series: $3,000-8,000. Highest profitability long-term.
Power Source
ASIC miners are power-hungry. Requirements vary by model:
- Voltage: Most miners require 220-240V (like your dryer/oven) — NOT standard 110V outlets
- Consumption: Expect 2,000-3,500W per miner (24/7 continuous draw)
- Breaker: Dedicated 20-30A circuit recommended
- Cost: Electrician install typically $500-3,000 depending on your setup
Note: Hosted mining eliminates this entirely—we handle all power infrastructure.
Internet Connection
Mining requires minimal bandwidth (typically <100 MB per day per miner), but needs to be stable. A basic home internet connection works fine. Latency isn't critical—you're solving puzzles, not gaming.
Mining Pool Account
Solo mining is impractical for individuals. Join a pool to get steady, predictable payouts. See the next section for how to choose.

Choosing a Mining Pool
Finding the right pool for your operation
Unless you control >1% of the network hashrate (~10 EH/s, or 50,000+ modern miners), solo mining won't produce consistent rewards. Mining pools solve this by combining the power of many miners and distributing rewards proportionally.
How Pools Work
- 1. You connect your miner to the pool's server with your unique worker credentials
- 2. The pool assigns "shares" of work to you and all other members
- 3. When anyone in the pool finds a block, the pool collects the reward (3.125 BTC + fees)
- 4. Rewards are distributed based on how many valid shares each miner contributed
- 5. Payouts occur regularly (daily, weekly, or when you hit minimum threshold)
Key Factors to Consider
Pool Fees
Typically 1-4% of your earnings. Lower isn't always better—reputation and uptime matter more. A 3% fee with 99.9% uptime beats a 1% fee with frequent downtime.
Payout Method
Common methods:
- FPPS: Predictable, includes transaction fees
- PPS+: Similar to FPPS, slightly higher variance
- PPLNS: Higher variance but potentially higher rewards
Pool Size
Larger pools find blocks more frequently (smoother payouts), but supporting smaller pools helps decentralization. Many miners split hashrate between pools.
Geography
Choose a pool with servers near you for lower latency. Most major pools have global server locations.
