How Crypto Mining Works

Mining is the process of using specialised hardware to validate transactions on a blockchain network. Miners compete to solve mathematical puzzles — the first to solve it earns the block reward (newly minted coins + transaction fees).

Proof of Work (PoW)

The original consensus mechanism used by Bitcoin. Miners use computational power to find a hash below a target difficulty. Energy-intensive but battle-tested over 15+ years. Used by BTC, LTC, KAS, ALPH, and others.

ASIC vs GPU Mining

ASICs are purpose-built for one algorithm and deliver 10-100x better efficiency than GPUs. GPU mining is largely dead since Ethereum moved to PoS. For profitable mining in 2026, ASICs are the only realistic option.

Mining Pools

Solo mining is like playing the lottery. Mining pools combine hashrate from thousands of miners and share rewards proportionally. Joining a pool gives you steady, predictable income instead of rare, large payouts.

Difficulty & Halving

Network difficulty adjusts to keep block times consistent as more miners join. Bitcoin halves its block reward every ~4 years (next: April 2028), reducing new supply. These dynamics directly affect profitability.

How We Evaluate Mining Hardware

Every miner on HodlChecker is evaluated using real-time network data and verified retailer pricing.

💰

Profitability

Daily revenue from current block rewards and network difficulty, minus electricity costs at $0.10/kWh.

⚡

Efficiency

Hashrate per watt (J/TH for Bitcoin, J/GH for others). More efficient = lower electricity costs = faster ROI.

📊

ROI Period

Hardware cost divided by daily profit. We show ROI in months so you know when the miner pays for itself.

🔧

Build Quality

Noise level, cooling design, power supply requirements, and manufacturer warranty terms.

🏪

Availability

Number of verified retailers, shipping costs, and whether the miner is in stock or pre-order.

Getting Started with Mining

1

Calculate profitability first

Check your electricity rate (look at your utility bill). Use our product pages to see daily profit at your rate. If a miner isn't profitable at your electricity cost, don't buy it.

2

Choose the right algorithm

Different coins use different algorithms. Bitcoin (SHA-256) requires expensive hardware. Kaspa (kHeavyHash) and Alephium (Blake3) have cheaper entry points with good ROI potential.

3

Buy from verified retailers only

ASIC mining is full of scams. Only buy from retailers listed on our product pages. Never pay via crypto to unknown sellers. If the price seems too good to be true, it is.

4

Plan for noise, heat, and power

ASICs are loud (70-80dB) and hot. You need dedicated space, adequate ventilation, and a power circuit that can handle the load. A single S21 draws 3,500W — more than most household circuits.

Frequently Asked Questions

Is crypto mining still profitable in 2026?
It depends on your electricity cost, hardware, and which coin you mine. Bitcoin mining requires industrial-scale operations to be profitable (electricity under $0.05/kWh). Altcoin mining (Kaspa, Litecoin, Alephium) can be profitable for smaller operators with efficient ASIC hardware and electricity under $0.10/kWh. Always calculate ROI before purchasing hardware.
What is an ASIC miner?
An ASIC (Application-Specific Integrated Circuit) miner is a device built specifically to mine a particular cryptocurrency algorithm. Unlike GPU mining, ASICs are optimised for one task and deliver much higher hashrates per watt. Examples include the Antminer S21 for Bitcoin (SHA-256) and the IceRiver KAS for Kaspa (kHeavyHash).
How much does it cost to start mining?
Entry-level ASIC miners start around $500-$1,000 for altcoin algorithms. Bitcoin ASIC miners range from $2,000-$15,000+ depending on efficiency. You also need to factor in electricity costs, cooling, noise management, and internet connectivity. Total startup costs for a home mining operation are typically $1,000-$5,000.
How do I calculate mining profitability?
Mining profitability = Daily Revenue - Daily Electricity Cost. Revenue depends on your hashrate, the coin's block reward, and network difficulty. Electricity cost = (Watts / 1000) × 24 hours × your electricity rate per kWh. ROI = Hardware Cost / Daily Profit. Our product pages calculate this automatically based on current network data.
What about GPU mining?
GPU mining became unprofitable for most coins after Ethereum moved to Proof of Stake in 2022. Some coins still support GPU mining (Ergo, Ravencoin, Flux), but returns are marginal compared to ASIC mining. For most people in 2026, ASIC mining is the only viable option for meaningful returns.
How noisy are ASIC miners?
Very. Most ASIC miners produce 70-80 decibels — comparable to a vacuum cleaner running 24/7. This makes home mining challenging unless you have a garage, basement, or dedicated space. Some newer models offer "silent" or hydro-cooled variants, but they cost significantly more.
