Peļņa un atmaksāšanās ir aplēses pēc šodienas monētu cenām un tīkla sarežģītības, pirms pūla maksām, hostinga un nodokļiem. Tās mainās katru dienu. Tas nav finanšu padoms.
Reitingi izmanto algoritma galveno monētu (BTC SHA-256, LTC + DOGE Scrypt): mazas blakus ķēdes šodien var maksāt vairāk par hešu, bet nespēj uzņemt daudz hešreita.
Bitmain Antminer S21 Pro (220Th) ir Bitmain ASIC ieguvējs SHA-256 algoritmam: 220 TH/s pie 3,300 W. Izlaists: 2024. g. jūlijs. Ar 15.0 J/TH tas ir par 26% efektīvāks nekā mūsu sekoto SHA-256 ieguvēju mediāna (20.4 J/TH). Pie $0.036/kWh tas pēc dienas peļņas ir 97. vietā no 299 SHA-256 ieguvējiem un nopelna ap $5.16 dienā, iegūstot BTC. Labākā cena AsicProfit ir $1,899. Pēc šodienas rādītājiem tas atmaksātos apmēram 368 dienās. Ar 75 dB tam vieta ir ieguves fermā vai hostinga centrā.

How reliable is the S21 Pro, and how long is the warranty?
AsicProfit SupportAsicProfit · 2026. g. 12. okt.
Owner reports vary by batch. Some farms see low failure rates and others report fan, power supply and hashboard problems within months. Fans and power supplies are the cheaper, easier fixes. Bitmain's shop gives 365 days of warranty from shipping for the original buyer, while resellers set their own terms. Keep intake air clean and within minus 20 to 45 C to reduce failures.

I pay high electricity rates, will an S21 Pro at home even cover its power bill?
AsicProfit SupportAsicProfit · 2026. g. 8. okt.
Your electricity price matters most. The S21 Pro uses about 3.5 kW, around 84 kWh a day, so at high household rates power can eat most or all of the earnings. Owners in expensive-power countries often host abroad or wait for cheaper tariffs. Put your exact rate into the calculator above. Reusing the heat in winter can also change the sums.

is the S21 Pro too loud to run in my house?
AsicProfit SupportAsicProfit · 2026. g. 6. okt.
For most homes, yes. Bitmain rates it at 76 dBA at full fan speed, with up to 550 CFM of airflow. That is far too loud for living space, and it runs around the clock. Owners put it in a garage, outbuilding or ducted room, or use shrouds to send the hot air somewhere useful. Any enclosure must still let it breathe, or it will overheat and throttle.

Do I need a special outlet for the S21 Pro, and does it come with a cord?
AsicProfit SupportAsicProfit · 2026. g. 5. okt.
It needs single-phase 220 to 277 V at up to 20 A, so plan a dedicated 240 V circuit. Standard 110 to 120 V outlets will not work. Bitmain includes a C20 power cord with the S21 Pro. Have an electrician fit the right receptacle and breaker for a continuous load of about 3.5 kW. Do not use extension cords or power strips.

What's different between the S21 Pro 234T and 245T?
AsicProfit SupportAsicProfit · 2026. g. 4. okt.
They are the same machine in different bins, both rated around 15 J/TH. Bitmain's current spec lists 245 TH/s at 3675 W, 234 TH/s at 3510 W and 220 TH/s at 3300 W. The 245T draws a little more power for a little more hashrate, so the better pick depends on the price gap. The calculator above compares them at your electricity price.

Is the S21 Pro the same as the S21 Hyd but with fans?
AsicProfit SupportAsicProfit · 2026. g. 16. sept.
Not exactly. Owners comparing the two report that both use the same generation of chips, but the boards and chip counts differ. The S21 Pro is air cooled on single-phase power at about 15 J/TH. The Hyd versions need three-phase power and a water loop, and push more hashrate per unit. Choose based on the cooling and power you can provide.
