Bitcoin (SHA-256) Miners
The flagship Antminer S21, WhatsMiner M-series, Avalon and SealMiner — bought and hosted.
Bitcoin is mined with SHA-256 ASICs — purpose-built machines that do nothing but hash, measured in terahashes per second (TH/s) and rated for efficiency in joules per terahash (J/TH). Since Bitcoin's 2024 halving cut the block reward, efficiency is everything: the lower a miner's J/TH, the more BTC it earns per dollar of electricity.
The current generation — Bitmain's Antminer S21 / S21 XP, MicroBT's WhatsMiner M60/M70, Canaan's Avalon A16, Bitdeer's SealMiner and Auradine's Teraflux — pushes efficiency toward 10–15 J/TH. Buy any of them from Bull Miners and host it on cheap green power from $0.018/kWh, where low-J/TH hardware earns the most. You own the machine and keep 100% of the BTC.

Bitcoin — frequently asked questions
What is the best Bitcoin miner in 2026?
On efficiency, the Antminer S21 XP / S21 Hydro, WhatsMiner M70 and Bitdeer SealMiner lead the field at roughly 10–15 J/TH. The 'best' for you depends on your budget and power cost — compare live specs and prices above.
Is Bitcoin mining profitable in 2026?
It can be, but post-halving it depends heavily on your electricity cost. A modern low-J/TH miner on cheap hosted power (from $0.018/kWh) is far more likely to be profitable than the same machine on expensive home electricity.
How much can a Bitcoin miner make per day?
Daily revenue per TH/s changes with BTC price and network difficulty. Multiply the current revenue-per-TH by your machine's TH/s, then subtract power cost. Cheap hosting power is what keeps the net positive — we can model it for your chosen miner.
What algorithm does Bitcoin use?
Bitcoin uses SHA-256. Only SHA-256 ASICs can mine it efficiently; GPUs and CPUs are not competitive.
Can I mine Bitcoin at home?
You can, but modern Bitcoin ASICs are loud (~75 dB) and hot, and home electricity is usually too expensive to profit. Most owners buy the hardware and host it with us instead, keeping the BTC without the noise, heat or power bills.
What's the most efficient Bitcoin miner?
Efficiency is measured in J/TH (lower is better). The Antminer S21 XP, WhatsMiner M70 and Bitdeer SealMiner hydro models are currently among the most efficient. See the comparison table above.
