New to mining? Here’s everything you need to go from zero to earning Bitcoin in 4 steps.
Pick an ASIC miner based on your budget, electricity cost, and mining goal. The Antminer S21 Pro is ideal for most miners — powerful, efficient, and widely supported.
Place your order on Bitmine.shop. Pay by crypto or wire transfer. We’ll confirm your order and dispatch your miner within 2–3 business days from our warehouse.
Connect your ASIC miner to power and ethernet. Log into the miner’s IP via your browser. Enter your mining pool details (e.g., F2Pool, AntPool, ViaBTC) and your Bitcoin wallet address.
Your miner starts hashing immediately. You’ll receive Bitcoin payouts directly to your wallet based on your share of the pool’s total hashrate. Sit back and watch it grow.
An ASIC (Application-Specific Integrated Circuit) miner is hardware built for one purpose only: to mine cryptocurrency. Unlike a GPU or CPU, an ASIC is hardwired to run a specific hashing algorithm — like SHA-256 for Bitcoin — making it far faster and more energy-efficient than any general-purpose computer.
For Bitcoin mining in 2025, ASIC miners are the only practical option. The most popular models are the Bitmain Antminer S21 Pro 234TH and the Antminer S21 XP 270TH, both available at Bitmine.
Bitcoin transactions are grouped into blocks. Miners compete to solve a complex mathematical puzzle (called “proof of work”) to validate the next block. The first miner to solve it earns the block reward — currently 3.125 BTC per block after the April 2024 halving — plus transaction fees.
The higher your hashrate (measured in TH/s), the more “guesses” your miner makes per second, and the higher your chance of earning rewards. This is why the Antminer S21 Pro 234TH is so valuable — it packs enormous hashing power into a single unit.
Modern ASIC miners come with built-in firmware that handles the mining software for you. You simply configure the miner’s IP dashboard with your mining pool URL and wallet address. Popular mining pools include AntPool, F2Pool, ViaBTC, and Foundry USA.
Yes — especially with efficient hardware and cheap electricity. The Antminer S21 Pro 245TH earns approximately $10–$15 per day at $0.04/kWh electricity, with ROI possible in 8–14 months at current Bitcoin prices. Use our mining calculator above to run your numbers.
