What does J/TH mean for a Bitcoin miner?

Joules per terahash (J/TH) measures how much electricity a machine uses to produce one terahash of computing power. It is the single most important specification: a lower number means the machine converts electricity into Bitcoin mining work more efficiently, which directly lowers your operating cost.

Hashprice is the daily revenue a miner earns per unit of computing power, usually quoted in dollars per terahash per day ($/TH/day). A miner's revenue is its hashrate multiplied by the current hashprice. Hashprice rises when the Bitcoin price or transaction fees go up, and falls when the total network hashrate (difficulty) rises or when a halving cuts the block subsidy. It is the single number that tells you whether mining is currently lucrative or tight.

How is a miner's daily revenue estimated?

Revenue is driven by hashprice, the daily revenue per terahash of computing power. As a formula, hashprice ($/TH/day) is approximately (block subsidy + average block fees) × 144 blocks per day × Bitcoin price ÷ total network hashrate. A miner's daily revenue is then its hashrate × hashprice. Because the inputs (Bitcoin price, network hashrate, transaction fees, and the block subsidy, which halves roughly every four years) all move constantly, these figures estimate today's conditions, not forecasts.

Which Bitcoin miner is the most profitable?

Profitability depends almost entirely on your electricity cost. Among modern machines, the most efficient models (lowest J/TH) earn the most per dollar of power, so the best choice is the most efficient miner you can run at your electricity rate. A highly efficient miner on cheap power beats a less efficient one almost every time.

Is Bitcoin mining still profitable in 2026?

Yes, for miners with efficient machines and low electricity costs. It comes down to hashprice versus your all-in cost per kilowatt-hour: an efficient modern miner at a competitive hosting rate can be solidly cash-flow positive, while older or inefficient machines on expensive power may not be.

How much does it cost to run a Bitcoin miner per day?

Daily electricity cost equals the machine's power in kilowatts multiplied by 24 hours and your electricity rate. For example, a 3,500 W miner at $0.07/kWh costs about $5.88 per day to run. If you host the machine with an operator, the hosting fee usually covers electricity, maintenance, and facility costs in one rate.

What is the difference between air, hydro, and immersion cooling?

Air-cooled machines use built-in fans and are the standard, lower-cost choice. Hydro-cooled machines circulate water through cooling plates inside the unit, and immersion machines are fully submerged in a non-conductive fluid. Beyond allowing higher power and hashrate per machine, hydro and immersion run more stably because cooling is more directed and controlled, and the sealed liquid keeps out dust and particles that shorten the life of air-cooled units. That makes liquid cooling especially advantageous in hot or dusty environments, or at sites with limited repair support, since air-cooled machines tend to fail somewhat more often. Hydro cooling also enables heat reuse, as at the Hashlabs facility in Finland where mining heat warms homes via the district heating network. Air-cooled machines are usually cheaper to buy.

How long does a Bitcoin miner remain competitive?

Typically three to five years, but it varies significantly with the market. When mining economics are strong (high hashprice), even older-generation machines can run at meaningful profit. When the market deteriorates and hashprice falls, only very efficient models stay cash-flow positive unless you have access to exceptionally cheap electricity. For that reason we generally recommend buying the most efficient models available, so they remain viable for many years before becoming obsolete. Machines can break, but are normally repairable at a reasonable cost.

Do I need to operate the miner myself?

No. With hosted mining, you own the hardware and a provider runs it for you in a professional facility, handling power, cooling, maintenance, and uptime, while the mined Bitcoin goes directly to your wallet. This is what Hashlabs does for clients across its facilities.

Can Hashlabs host a miner that isn't listed here?

In most cases, yes. Hashlabs operates hosting sites that can accommodate the large majority of machines on this list. If the miner you want isn't shown in our packages, send us a request; we are flexible and can usually host it.

Earnings are estimates at current network difficulty, fees, and Bitcoin price, which change constantly — not financial advice or a forecast of future results.

Revenue, gross profit, gross margin, and revenue per kWh are shown only for BTC miners because those calculations use live Bitcoin network data.

What does J/TH mean for a Bitcoin miner?: Joules per terahash (J/TH) measures how much electricity a machine uses to produce one terahash of computing power. It is the single most important specification: a lower number means the machine converts electricity into mining work more efficiently, which directly lowers your operating cost.
What is hashprice?: Hashprice is the daily revenue a miner earns per unit of computing power — usually quoted in dollars per terahash per day ($/TH/day). A miner's revenue is simply its hashrate multiplied by the current hashprice. Hashprice rises when the Bitcoin price or transaction fees go up, and falls when the total network hashrate (difficulty) rises or when a halving cuts the block subsidy.
How is a miner's daily revenue estimated?: Revenue is driven by hashprice. As a formula, hashprice ($/TH/day) ≈ (block subsidy + average block fees) × 144 blocks per day × Bitcoin price ÷ total network hashrate. A miner's daily revenue is then its hashrate × hashprice. Because Bitcoin price, network hashrate, transaction fees, and the block subsidy all move constantly, these figures are estimates of today's conditions, not forecasts.
Which Bitcoin miner is the most profitable?: Profitability depends almost entirely on your electricity cost. Among modern machines, the most efficient models (lowest J/TH) earn the most per dollar of power. A highly efficient miner on cheap power beats a less efficient one almost every time.
Is Bitcoin mining still profitable in 2026?: Yes, for miners with efficient machines and low electricity costs. It comes down to hashprice versus your all-in cost per kilowatt-hour: an efficient modern miner at a competitive hosting rate can be solidly cash-flow positive, while older or inefficient machines on expensive power may not be.
How much does it cost to run a Bitcoin miner per day?: Daily electricity cost equals the machine's power in kilowatts multiplied by 24 hours and your electricity rate. For example, a 3,500 W miner at $0.07/kWh costs about $5.88 per day to run. If you host the machine with an operator, the hosting fee usually covers electricity, maintenance, and facility costs in one rate.
What is the difference between air, hydro, and immersion cooling for Bitcoin miners?: Air-cooled machines use built-in fans and are the standard, lower-cost choice. Hydro-cooled machines circulate water through cooling plates inside the unit, and immersion machines are fully submerged in a non-conductive fluid. Hydro and immersion run more stably and enable heat reuse — as at the Hashlabs facility in Finland, where mining heat warms homes via the district heating network. Air-cooled machines are usually cheaper to buy.
How long does a Bitcoin miner remain competitive?: Typically three to five years, but it varies with the market. When mining economics are strong, even older machines can run profitably. When hashprice falls, only very efficient models stay cash-flow positive — unless you have access to exceptionally cheap electricity.
Do I need to operate the miner myself?: No. With hosted mining, you own the hardware and a provider runs it for you in a professional facility — handling power, cooling, maintenance, and uptime — while the mined Bitcoin goes directly to your wallet. This is what Hashlabs does for clients across its facilities.
Can Hashlabs host a miner that isn't listed here?: In most cases, yes. Hashlabs operates hosting sites that can accommodate the large majority of machines on this list. If the miner you want isn't shown in our packages, send us a request; we are flexible and can usually host it.
