Current ASIC Miners for Bitcoin Mining — Comparison
Looking to buy a bitcoin miner? Antminer from Bitmain, Whatsminer from MicroBT, and Sealminer from Bitdeer all deliver powerful bitcoin mining hardware for sale. The decisive factor when choosing a miner is efficiency in joules per terahash (J/TH) — the lower, the more bitcoin produced per kilowatt-hour of electricity.
At Minenity you can buy ASIC miners and host them directly — everything from one partner. Every miner runs in a professional data center on industrial power from €0.062/kWh. You receive an invoice and serial number; the hardware stays your property. Whether you're entering the market with a single Antminer or building out a larger mining rig, we advise you personally on hardware selection, location, and profitability.

Buy Antminer — the Bitmain lineup
Bitmain is the market leader among ASIC manufacturers — the majority of the global Bitcoin hashrate runs on Antminer hardware. We carry the current Antminer S21 generation: the Antminer S21+ 235T as the price-performance pick, the Antminer S21 Pro at 15 J/TH efficiency, and the Antminer S21 XP 270T as the air-cooled flagship. Which model fits which setup is covered in our complete Antminer S21 series guide.
Buy Whatsminer — the MicroBT alternative
MicroBT is the second-largest manufacturer, and professional operators know it for one thing: durability. Whatsminers have a reputation for low-maintenance 24/7 operation — often the argument for mixed fleets. In the shop we carry the Whatsminer M60S+ 206T as the most affordable entry into professional bitcoin mining and the Whatsminer M61S+ 220T with more hashrate per unit.
Buy Sealminer — Bitdeer’s efficiency series
Bitdeer is the youngest of the three manufacturers and takes direct aim at the incumbents’ efficiency numbers with the Sealminer A2 series. The Sealminer A2 222T delivers 14.9 J/TH at a competitive price — a real alternative for buyers who don’t automatically default to the market leader. Like every unit we sell, each Sealminer runs bundled with professional ASIC miner hosting in the US or Asia.

ASIC miners: the essentials before you buy
What is an ASIC miner?
An ASIC miner (Application-Specific Integrated Circuit) is a computer built for exactly one job: computing Bitcoin’s SHA-256 algorithm. Unlike a PC or a graphics card it can do nothing else — but it does that one job thousands of times more efficiently. Current units like the Antminer S21+ deliver 235 trillion operations per second (235 TH/s) at around 3,500 watts.
Every miner worldwide competes to find the next block of the blockchain. The winner earns the block reward — currently 3.125 BTC plus transaction fees. The more hashrate a machine contributes and the less power it draws, the more profitably it runs. That makes efficiency in joules per terahash (J/TH) the single most important number when buying.
Which ASIC miner pays off in 2026?
The honest answer depends on two variables: your power rate and your time horizon. Our rule of thumb from consulting: with hosting power from €0.062/kWh, virtually every current S21-class model (under 17 J/TH) stays profitable across its service life. The Antminer S21 XP 270T has the best air-cooled efficiency in our lineup (13.5 J/TH), the Antminer S21+ 235T the best price-performance ratio, and the Whatsminer M60S+ the most affordable entry.
Critical for any calculation: the next Bitcoin halving in April 2028 cuts the block reward in half. Always run your preferred model through the bitcoin mining calculator with the live BTC price and current difficulty. More buying criteria in our guide how to buy an ASIC miner.
Buying from a European dealer: warranty, customs, shipping
Importing directly from China means handling customs clearance, import VAT, CE-conformity risk, and — in a warranty case — shipping the unit back to Asia. Buying through Minenity removes all of that: your contract partner is 21 Strategy GmbH (Berlin, HRB 158158 B) under European contracts. Warranty handling runs through us — you never deal with Bitmain or MicroBT yourself.
And because every miner ships straight from the manufacturer to our data center in the US or Asia, there is no import bureaucracy and no shipping risk for you — your unit produces from day one on industrial power instead of waiting in a box. Ownership, invoice, and serial number are yours, of course.
