How to Start Cryptocurrency Mining in 2025

If you're considering starting crypto mining in 2025, this clear, practical guide covers everything you need. We'll focus exclusively on ASIC mining, giving you actionable steps to set up your equipment correctly and profitably, from selecting hardware to scaling your operations.

Step 1: Choose the Right ASIC Miner in 2025

Your first task is selecting an ASIC miner based on the cryptocurrency you want to mine. Here are the best ASIC mining options available in 2025:

Bitcoin (SHA-256)

  • Bitmain Antminer S21:
    • Hashrate: 200–234 TH/s
    • Power: ~3500 W
    • Efficiency: ~15 J/TH
    • Coins: Bitcoin (BTC), Bitcoin Cash (BCH)

Litecoin & Dogecoin (Scrypt)

  • Bitmain Antminer L9:
    • Hashrate: 16 GH/s
    • Power: ~3360 W
    • Coins: Litecoin (LTC), Dogecoin (DOGE), other Scrypt coins
    • Elphapex DG1+:
    • Hashrate: 14.4 GH/s
    • Power: 3950 W
    • Ideal for: Higher-performance Scrypt mining setups.

  • Elphapex DG Home:

    • Hashrate: ~2.1 GH/s
    • Power: 630 W (liquid-cooled, quiet)
    • Ideal for: Home-friendly Litecoin/Dogecoin mining.

Kaspa (kHeavyHash)

  • Bitmain Antminer KS5 Pro:
    • Hashrate: ~21 TH/s
    • Power: ~3150 W
    • Efficiency: ~150 J/TH
    • Coin: Kaspa (KAS)

Aleo (zkSNARK)

  • IceRiver AE1 Lite:
    • Hashrate: ~300 MH/s
    • Power: 500 W
    • Ideal for: Home mining due to low power and compact size.
    • Coin: Aleo (ALEO)

Tip: When selecting a miner, always consider upfront cost, energy efficiency, and profitability relative to your electricity rate.

Step 2: Plan Electricity Requirements and Costs

Electricity is your largest operating cost. Plan accordingly:

  • Voltage and circuits:
    Most high-powered ASIC miners require 220–240V AC. Ensure your electrical infrastructure can support the miner’s wattage safely, typically needing dedicated circuits for each miner.
  • Heat & ventilation:
    A 3.5kW miner generates substantial heat (like running multiple space heaters). Ensure adequate cooling, ventilation, or dedicated mining space to prevent overheating.
  • Calculate energy costs:
    Formula: (Miner wattage × 24 hours) ÷ 1000 = daily kWh consumption
    Example: 3500W miner × 24 hrs = 84 kWh/day. At €0.07/kWh, daily cost is ~€5.88/day.
  • Profitability estimates:
    Use ASIC mining calculators (Minerstat, ASIC Miner Value, WhatToMine) regularly to project earnings and ROI. Aim for ROI within 12–18 months or less.

Step 3: Setting Up Your Mining Hardware and Pool

Once your miner arrives, follow these steps:

  • Physical setup:
    Place the miner in a cool, ventilated space. Connect to a suitable power source (220V recommended) and Ethernet cable to your router.
  • Find miner’s IP address:
    Check your router’s device list or use a network scanner to locate the miner's IP.
  • Access miner interface:
    Enter the miner’s IP in your browser, log in (default often admin/admin root/root), then immediately change the default password for security.
  • Connect to mining pool:
    In miner settings, enter:
    • Pool URL (provided by your chosen pool, e.g., stratum+tcp://pool.address:port)
    • Wallet address or username (for pool payouts)
    • Worker name (optional, helps identify your device)

Always set a secondary (backup) pool to avoid downtime.

  • Monitor performance:
    Check your miner and pool dashboard regularly for temperatures, hashrate, and rejected shares. Ideal chip temperatures are typically below 85°C.

Step 4: Create a Crypto Wallet for Payouts

Your mining rewards need secure storage:

  • Choose a wallet:
    Select a trusted wallet compatible with your cryptocurrency (hardware wallets like Ledger or software wallets like Exodus).
  • Setup & backup:
    Secure your wallet by backing up seed phrases offline and enable all security features (2FA, encryption).
  • Link wallet to pool:
    Input your wallet’s receiving address into the mining pool settings for automatic payouts.
  • Manage payouts:
    Pools usually payout after you reach a minimum threshold. Track your earnings and regularly move funds to cold storage or exchanges as desired.

Step 5: Estimate Mining Profitability and ROI

Profitability depends on four main factors:

  • Electricity cost
  • Miner hashrate
  • Network difficulty
  • Cryptocurrency prices

Regularly assess profitability (at least monthly) using online calculators. Understand your ROI clearly:
ROI (days) = Total investment ÷ Daily net profit

Aim for rapid ROI (12–18 months). If profitability decreases, reassess your setup or consider relocating miners to cheaper electricity.

Step 6: Ensure Security and Avoid Common Mistakes

Protect your equipment and earnings by:

  • Changing miner’s default passwords.
  • Never exposing miners directly to the internet (use VPN if remote access needed).
  • Regularly cleaning miners to prevent overheating.
  • Avoiding cheap or unsafe electrical setups (dedicated circuits required).
  • Avoiding common beginner mistakes:
    • Underestimating miner noise and heat.
    • Ignoring electricity costs.
    • Overinvesting without experience (start small).
    • Falling for scams or buying from unknown vendors.
    • Poor wallet security (always secure keys offline).
