Bitcoin Mining at Home in 2026: Is It Still Worth It?

Bitcoin mining at home is still possible in 2026, but whether it pays depends almost entirely on two numbers: the price of your electricity and the efficiency of your machine. This guide explains how mining income is calculated, walks through the realistic home options from tiny open-source miners to full-size ASICs, compares pools and hosting, and runs the actual math with network data as of 8 November 2026.

The short version: a modern full-size miner can roughly break even or turn a small profit on cheap power, small home miners are best treated as a hobby or a lottery ticket, and mining heaters make the most sense when you would be paying for electric resistance heat anyway. The details below show why.

How Bitcoin mining income works

Miners compete to find a valid block by running the SHA-256 hash function trillions of times per second. Roughly every ten minutes, one miner or pool finds a block and collects the block reward. That reward has two parts.

• The block subsidy. New bitcoin created with each block. It has been 3.125 BTC since the April 2024 halving and drops to 1.5625 BTC at block 1,050,000, which at the current pace is expected around 2028.
• Transaction fees. Paid by users whose transactions go into the block. Fees rise when the network is busy and fall when it is quiet. Over the 1,008 blocks (about one week) before 8 November 2026, fees averaged about 0.022 BTC per block, according to mempool.space data, which means the subsidy still makes up more than 99 percent of miner revenue.

Hashrate and difficulty

Your share of the roughly 144 daily blocks is proportional to your share of the total network hashrate. If your machine produces 200 terahashes per second (TH/s) and the network produces about 1,000 exahashes per second (EH/s, where 1 EH/s equals 1,000,000 TH/s), you contribute about one five-millionth of the work.

The network keeps blocks near ten minutes by adjusting the difficulty every 2,016 blocks (about two weeks). When more machines join, difficulty rises and every existing miner earns less bitcoin per terahash. This is the most important thing to understand about home mining: your machine's output does not change, but its share of the reward shrinks as the network grows.

Hashprice: the one number that summarizes it

Miners talk about hashprice, the expected revenue from one petahash per second (1,000 TH/s) of hashrate for one day. It combines subsidy, fees, difficulty, and the bitcoin price into a single figure. With the network data in this guide, hashprice works out to about 0.000427 BTC, or roughly $31.60, per PH/s per day before pool fees. Multiply that by your hashrate in PH/s and you have your expected gross daily revenue.

The assumptions used in this guide

Every figure below is a snapshot. Change any one of these and the results change with it.

• Date: 8 November 2026.
• Bitcoin price: $74,160, the approximate last trade on the Kraken BTC/USD market at the time of writing.
• Network difficulty: 148.36 trillion, reported by mempool.space. That difficulty corresponds to about 1,062 EH/s if blocks arrive exactly every ten minutes.
• Observed hashrate: mempool.space estimated about 976 EH/s over the prior three days, and blocks were arriving slower than ten minutes. The next difficulty adjustment, expected around 13 November 2026, was projected to be roughly 5.5 percent lower. A lower difficulty would raise every result in this guide by a similar amount, until it rises again.
• Fees: 0.022 BTC average per block, for a total of 3.147 BTC per block.
• Pool fee: 2 percent, a round number for comparison. Actual fees vary by pool and are covered below.
• Uptime: 100 percent, 24 hours a day, at the manufacturer's stated hashrate and power draw.
• Not included: the purchase price of the hardware, shipping, import duties, repairs, internet, cooling costs, and taxes.

The calculation, done directly from difficulty, is:

daily BTC = hashrate (H/s) × 86,400 ÷ (difficulty × 2^32) × 3.147 × (1 − pool fee)

This equals the simpler (your TH/s ÷ network TH/s) × 144 × (3.125 + fees per block) when the network hashrate is the one implied by difficulty, which avoids relying on a noisy hashrate estimate.

The home mining options

Home miners fall into three broad groups. They differ by a factor of more than 200 in hashrate, and by just as much in noise, power, and setup effort.

Open-source lottery miners: Bitaxe

Bitaxe is an open-source Bitcoin miner: the hardware design files and the ESP-Miner firmware are published, and the device is configured through a browser dashboard called AxeOS. The single-chip Bitaxe Gamma uses the BM1370 chip, the same ASIC used in the Antminer S21 Pro, and the project estimates its output at about 1.2 TH/s. Power draw is roughly in the 15 to 20 watt range depending on settings, and the official repository notes the power supply must deliver more than 20 W.

A Bitaxe is quiet, sits on a desk, plugs into a standard power adapter, and can point at any Stratum pool or at your own node. It also makes very little money. Its real appeal is learning how mining works, supporting decentralized mining, and solo mining as a long-odds lottery. Bitaxe units are sold by several companies, including D-Central Technologies, a Quebec-based company that also offers ASIC repair and sells space-heater editions of mining hardware.

Mining heaters: Heatbit and Avalon Nano

Mining heaters package a small ASIC in a quiet enclosure built to warm a room. Every watt a miner consumes ends up as heat, so in winter the electricity is doing double duty.

• Heatbit states that its Heatbit Trio delivers about 10 TH/s at 400 W of mining power, with an additional 1,100 W conventional heating coil for colder days, a 1,500 W total, and up to 45 dB at full power. Heatbit's site showed its heaters as sold out for the season at the time of writing, so check current availability.
• Canaan, which makes the Avalon line, lists the Avalon Nano 3S at about 6 TH/s with a 140 W maximum power draw from a 28 V adapter. Canaan's launch materials give a noise range of roughly 30 to 40 dB.

The honest way to judge a mining heater is against the heater it replaces. If the alternative is a plug-in electric resistance heater, the heat costs the same either way and the mining income is a partial rebate. If the alternative is a heat pump, which typically moves several units of heat for each unit of electricity, a mining heater produces less heat per dollar of power, and the small mining income rarely closes that gap.

Full-size ASIC miners: Bitmain, MicroBT, Canaan

This is where meaningful hashrate lives. The three major manufacturers are Bitmain (Antminer), MicroBT (Whatsminer), and Canaan (Avalon). Two Bitmain examples, using figures from Bitmain's own specification pages:

• Antminer S21: 200 TH/s at about 3,500 W at the wall, an efficiency of 17.5 joules per terahash (J/TH), on a 220 to 277 V AC input.
• Antminer S21 XP: a typical 270 TH/s at 3,645 W at the wall, or 13.5 J/TH, with hashrate and power tolerances of a few percent.

Running one at home is a real project:

• Power: a single air-cooled unit draws about as much as two or three space heaters running at once, all day. In North America that means a dedicated 240 V circuit, installed and sized by a licensed electrician for a continuous load. A standard 120 V household outlet is not suitable.
• Noise: air-cooled ASICs use high-speed fans and are far too loud for living space. Most home operators put them in a garage, basement, or outbuilding, add sound-dampening enclosures, or use immersion or hydro cooling setups.
• Heat: about 3.5 kW of continuous heat has to go somewhere. In summer it needs to be exhausted outside, or the machine will throttle and the room will overheat.
• Insurance: check your policy and local electrical code before running industrial hardware around the clock.

The math: what each option earns as of 8 November 2026

The table applies the assumptions above to each machine. Revenue is after the 2 percent pool fee. Net figures subtract electricity only; hardware cost is not included.

Miner	Hashrate	Power	Sats per day	Revenue per day	Net per day at $0.08/kWh	Net per day at $0.12/kWh	Net per day at $0.16/kWh	Break-even power price
Bitaxe Gamma	1.2 TH/s	about 18 W	about 50	$0.04	$0.00	-$0.02	-$0.03	about $0.086/kWh
Avalon Nano 3S	6 TH/s	140 W	about 251	$0.19	-$0.08	-$0.22	-$0.35	about $0.055/kWh
Heatbit Trio (mining only)	10 TH/s	400 W	about 418	$0.31	-$0.46	-$0.84	-$1.23	about $0.032/kWh
Antminer S21	200 TH/s	3,500 W	about 8,360	$6.20	-$0.52	-$3.88	-$7.24	about $0.074/kWh
Antminer S21 XP	270 TH/s	3,645 W	about 11,290	$8.37	$1.38	-$2.13	-$5.62	about $0.096/kWh

What the numbers say

• Efficiency decides everything. The S21 XP's break-even electricity price is about $0.096 per kWh, while the older-efficiency S21 needs power below about $0.074. The gap comes entirely from joules per terahash.
• Typical household power is too expensive for pure profit. Many households pay $0.12 per kWh or more. At those rates even the most efficient machine in the table loses money on electricity alone, before paying back its purchase price.
• Small miners are not income. A Bitaxe on a pool earns roughly a dollar a month. Its value is educational, or as a solo-mining lottery ticket.
• Heaters need to be judged as heaters. On mining revenue alone, the Heatbit Trio loses money at any common power price. In heating season, if its 400 W would otherwise be spent on resistance heat, the roughly $0.31 per day of mining revenue becomes a discount on your heating bill instead.

Over a 30-day month at $0.08 per kWh, an S21 XP would bring in about $251 against about $210 of electricity, roughly $41 before hardware costs. At $0.12 per kWh it would lose about $64 a month.

Why your results will drift

Difficulty adjusts every two weeks, and over the long run it has tended to rise as more efficient hardware ships. Each increase cuts the bitcoin your machine earns. The bitcoin price can rise or fall far more than difficulty in a given month. The next halving, expected around 2028, will cut the subsidy in half overnight. Any payback estimate that assumes today's numbers hold for two or three years is optimistic.

Pools: FPPS, PPLNS, TIDES, and solo

A single home miner would almost never find a block alone, so most miners join a pool, which combines hashrate and shares the rewards. Pools mainly differ in how they pay you. Compare them in the mining pools section.

FPPS (Full Pay Per Share)

The pool pays a fixed expected amount for every valid share you submit, plus a share of transaction fees, whether or not the pool finds blocks that day. The pool takes on the luck risk, which is why FPPS fees are usually higher. Income is smooth and predictable.

• Foundry USA Pool pays all members under FPPS, calculated daily per subaccount. It requires completing a client onboarding process and is oriented toward larger operations.
• Braiins Pool uses FPPS, offers on-chain or Lightning payouts, and states a 0 percent pool fee for machines running Braiins OS firmware. Braiins also offers a separate solo mining service.
• Luxor runs an FPPS pool aimed at professional miners and also publishes widely used hashprice data.

PPLNS and TIDES

Pay Per Last N Shares pays only when the pool actually finds a block, split among miners according to their recent shares. Income is lumpier, but fees can be lower and there is no pool-side luck premium.

OCEAN uses TIDES (Transparent Index of Distinct Extended Shares), a variant in which each block reward is split according to a share window of eight blocks' worth of work. OCEAN pays miners directly in the block's coinbase transaction where possible, so the pool does not hold balances for those miners, supports Lightning payouts through BOLT12, and states a 2 percent fee, cut to 1 percent for miners who build their own block templates with its DATUM protocol. The tradeoff: on a pool with a smaller share of network hashrate, payouts arrive less evenly.

Solo mining

Solo mining means pointing your miner at your own node or a solo service and keeping the whole block reward if you find one. With the numbers in this guide, a 1.2 TH/s Bitaxe has roughly a one in six million chance of finding a block on any given day, which works out to an expected wait of more than 16,000 years. A 200 TH/s S21 would expect about one block per century.

Hashrate marketplaces

NiceHash is a hashrate marketplace: you connect your machines, buyers rent the hashpower, and you are paid in BTC for every share. It is simple to start with, though what you earn depends on marketplace demand rather than directly on pool rewards.

Hosting: mining without the noise at home

If your home electricity is expensive, the noise is a dealbreaker, or you lack a 240 V circuit, a hosting provider runs your machines in a data center for a fee. Browse providers in the mining hosting section.

• Simple Mining hosts machines in Iowa, advertises all-in rates starting from $0.065 per kWh with no minimum quantity, bills only for hours a machine is hashing, and repairs machines in-house.
• Compass Mining sells hardware with hosting at partner facilities and bills a flat prepaid monthly fee per miner that covers electricity, security, and monitoring. Compass notes that rates can change when the facility's electricity price changes.

Before signing, read the hosting agreement closely: what uptime is guaranteed, who pays for repairs, how long a broken machine can sit offline, how rate changes work, and how you can get your hardware back. Hosting removes the noise and power problems, but adds counterparty risk. Compare the all-in hosting rate to the break-even prices in the table above.

Buying hardware: what to check

Browse makers and resellers in the mining hardware section. Before buying any ASIC:

1. Calculate efficiency. Divide watts by TH/s to get J/TH. Lower is better and matters more than raw hashrate for profitability.
2. Get the current price from the seller. ASIC prices move with hashprice. A machine that looks cheap may be cheap because it barely covers its power cost.
3. Estimate payback with a falling hashprice. Assume difficulty keeps rising and remember the 2028 halving.
4. Check power requirements. Confirm input voltage, plug type, and circuit size before the machine arrives.
5. Check warranty and repair options. Find out where repairs happen and how long they take. Every day offline is lost revenue.

Taxes and paperwork

In many countries, mined bitcoin is treated as income when you receive it, valued at its market price that day, and selling it later can create a separate capital gain or loss. In the United States, the IRS treats mined coins as income at fair market value when received, and mining as a trade or business can also bring self-employment tax and the ability to deduct expenses such as electricity. See the IRS digital assets guidance for the official position, and consider crypto tax software or a Bitcoin-savvy accountant to track the cost basis of every payout. Rules differ by country, so check local guidance.

Also plan where payouts go. Pool balances and hosting accounts are custodial until withdrawn. Sending payouts to a wallet you control, such as one of the hardware wallets listed on Bitcoin Lando, removes that exposure.

So, is home mining worth it in 2026?

• Worth it for profit if you have electricity well under about $0.09 per kWh, a current-generation machine around 13 to 15 J/TH, a place where the noise and heat are acceptable, and a plan for a falling hashprice.
• Worth it as a heater if you would otherwise use electric resistance heat, so the mining income offsets a cost you already pay.
• Worth it as a hobby with a Bitaxe or small miner, for learning, supporting decentralized mining, and the remote chance of a solo block.
• Not worth it for profit on typical residential power with older-efficiency machines. Compare the miner's cost with simply buying bitcoin, or look at cheaper hosted power.

Frequently asked questions

Can a home miner still find a Bitcoin block?

Yes, but the odds are tiny. With difficulty as of 8 November 2026, a 1.2 TH/s miner has roughly a one in six million chance per day, and a 200 TH/s machine would expect about one block per century. Joining a pool turns that rare jackpot into small, regular payouts.

Is a Bitcoin mining heater better than a regular space heater?

Compared with a plug-in resistance heater, a mining heater turns the same electricity into the same heat and also earns a small amount of bitcoin. Compared with a heat pump, it usually costs more to produce the same heat.

Which pool payout method is best for a small miner?

FPPS gives the steadiest income because the pool pays per share regardless of luck. PPLNS and TIDES pay only when the pool finds blocks but can carry lower fees and, in OCEAN's case, pay directly from the block reward. Small miners who value predictability usually prefer FPPS.

Can you run an Antminer on a normal household outlet?

No. A full-size unit such as the Antminer S21 draws about 3,500 W on a 220 to 277 V input. In North America that requires a dedicated 240 V circuit installed by a qualified electrician.

Is mined bitcoin taxable?

In many countries it is taxed as income when received, at its market value that day. In the United States, the IRS treats mined coins as income at fair market value. Keep records of every payout and check the rules where you live.
