How to Mine Bitcoin: A Practical Step-by-Step Guide

Take a recent electricity bill, divide the total amount owed by the kilowatt-hours consumed, and use that number. It includes delivery charges, taxes and tiered pricing, which the headline tariff usually hides. Miners who model on the advertised rate consistently overestimate profit by twenty to forty percent.

If the resulting figure is above roughly twelve cents per kilowatt-hour, plan on current-generation efficient hardware or hosting instead of buying older machines. Below six cents, cheap previous-generation units become very attractive because the electricity penalty is tolerable.

A full-size ASIC needs a dedicated 240 volt circuit — typically a 30 amp breaker per machine with a matching NEMA or IEC outlet — and continuous airflow to exhaust three to five kilowatts of heat. Intake air above 35 degrees Celsius will throttle the machine and shorten hardware life.

Decide the location before you buy: garage, outbuilding, shed, warehouse or hosted facility. Living spaces are ruled out by noise unless you choose a hydro unit or a low-power home miner. If none of these fit, skip straight to hosting.

With your power rate and site constraints known, hardware selection becomes arithmetic. Compare candidates on joules per terahash and delivered dollars per terahash, then check the physical fit: PSU voltage, plug type, noise, and whether the unit is air, hydro or immersion cooled.

Buy from a supplier that documents condition and tests units before shipping. Every machine we sell is bench-tested, condition-graded as new, used or refurbished, and quoted at a delivered price so there are no customs surprises.

Set up a bitcoin wallet you control and copy its receiving address. Then create an account at a reputable pool, add that address as your payout destination, and note the pool's stratum URL and port for your region. Doing this while you wait for delivery means the miner can start earning the day it lands.

Choose a pool on payout scheme and reliability rather than headline fee. PPS-style payouts give steady, predictable income; PPLNS pays more when luck runs well but varies week to week. Either is fine — inconsistent uptime costs you far more than the fee difference.

Connect ethernet and power, then find the miner's IP address using your router's client list or the manufacturer's scanning tool. Log into the web interface, change the default password immediately, and enter your pool URL with your worker name and, where required, your wallet address as the username.

Within a few minutes the dashboard should show all hashboards online and a hashrate close to the rated figure. Expect roughly 95 percent of the datasheet number in a warm room — that derating is normal, not a fault.

Once stable, check chip temperatures and fan speeds under load. Underclocking or undervolting slightly often improves joules per terahash and materially extends hardware life; aggressive overclocking buys a few percent hashrate for disproportionate heat and failure risk. Only run custom firmware from sources you trust.

Set up alerts for offline workers on your pool dashboard, keep the intake filters clean, and hold a spare power supply and fan set on the shelf. A machine at 98 percent uptime beats a faster machine that spends three weeks a year waiting on parts, and our repair centre turns around hashboard and PSU faults for customers worldwide.
