Zisk a návratnosť sú odhady z dnešných cien kryptomien a obtiažnosti siete, pred poplatkami poolu, hostingom a daňami. Menia sa každý deň. Nejde o finančné poradenstvo.
Rebríčky používajú hlavnú kryptomenu algoritmu (BTC pre SHA-256, LTC + DOGE pre Scrypt): malé vedľajšie siete môžu dnes platiť viac za hash, ale veľa hashrate neuniesú.
Bitmain Antminer S21+ Hyd (338Th) je ASIC ťažobný stroj od Bitmain pre algoritmus SHA-256 s výkonom 338 TH/s pri 5,070 W. Uvedený na trh: august 2025. So spotrebou 15.0 J/TH je o 26 % úspornejší než medián strojov SHA-256, ktoré sledujeme (20.4 J/TH). Pri $0.036/kWh je na 54. mieste z 299 strojov SHA-256 podľa denného zisku a zarobí zhruba $7.93 denne ťažbou BTC. Najlepšia cena na AsicProfit je $2,099. Pri dnešných hodnotách sa zaplatí zhruba za 265 dní. Je chladený vodou (hydro), takže namiesto ventilátorov potrebuje chladiaci okruh a suchý chladič.

What is the difference between the S21+ air versions and the S21+ Hyd versions on this page?
AsicProfit SupportAsicProfit · 20. 10. 2026
They are different machines. The air-cooled S21+ runs on single-phase 220 to 277 V with fans. The S21+ Hyd is water cooled and needs a three-phase 380 to 415 V supply, a coolant loop with 8 to 10 L/min of flow, and a dry cooler or similar heat exchanger. In return the Hyd gives much more hashrate per unit, and Bitmain rates the 358 TH/s Hyd at 15 J/TH. The numbers in each version name are the rated hashrate bins.

What water do I put in the S21+ Hyd loop? Can I just use tap water?
AsicProfit SupportAsicProfit · 14. 10. 2026
Do not use tap water. Bitmain lists antifreeze, pure water or deionized water as working coolants, each with its own pH window: antifreeze 7.0 to 9.0, pure water 6.5 to 7.5, deionized water 8.5 to 9.5. Keep the inlet between 20 and 50 C, flow at 8 to 10 L/min and pressure at or below 3.5 bar. Where frost is possible, Bitmain says to use antifreeze rather than pure water.

My S21+ mines for a few minutes then stops and shows a board error. Is it dead?
AsicProfit SupportAsicProfit · 6. 10. 2026
Not necessarily. Owners on Bitcointalk report this with S21+ units and often trace it to one hashboard, a loose data or power connection, or damage from rough shipping. Test one board at a time: power down, disconnect one board's data cable and power, and see whether the rest run. Check the kernel log for chip counts on each chain. If the unit is still under warranty, contact the seller before opening it.

What warranty comes with an S21+? I'm not buying straight from Bitmain.
AsicProfit SupportAsicProfit · 30. 9. 2026
Bitmain gives 365 days from the shipping date on the S21+ and S21+ Hyd, but only to the original buyer who bought directly from Bitmain. If you buy from a reseller, the reseller is responsible for the warranty, so ask them for the terms in writing before paying. Running the miner outside Bitmain's specified conditions, or changing settings without approval, can void cover.

how loud is the S21+ really? thinking of putting one in my garage
AsicProfit SupportAsicProfit · 29. 9. 2026
Bitmain rates the air-cooled S21+ at 76 dBA at full fan speed, which is about as loud as a busy vacuum cleaner and runs around the clock. A detached garage or outbuilding works for many owners, but it is too loud for living space. Owners on forums say enclosures and ducting can take some of the edge off, but every enclosure still has to move a lot of air, so heat and airflow must come first.
Jan D. · 15. 9. 2026 · k inej verzii
Can I plug the air-cooled S21+ into a normal wall socket, or do I need something special?
AsicProfit SupportAsicProfit · 16. 9. 2026
You need a 220 to 277 V single-phase supply. Bitmain lists a maximum input current of 20 A for the 216 TH/s unit, so plan a dedicated circuit sized for it rather than a shared household socket. The machine ships with a C20 power cord. A 110 to 120 V outlet will not work, and Bitmain warns that the wrong input voltage can damage the unit. Have an electrician check the circuit, breaker and plug before you switch it on.
