MicroBT M21S at 56 TH/s on universal AC. Higher tier of the M20 generation. 3,360W at 75 dB on 100 to 240V. The AC input without PSU is the deployment advantage. 56 TH/s is below the competitive threshold at current difficulty on standard electricity. 155 x 240 x 390mm at 12.5 kg. 100-240V input. Ethernet. 5 - 45 °C. MicroBT firmware. Daily electricity $5.64. Monthly: $169. The Whatsminer M21S competes against the full Bitcoin network hashrate of 600+ EH/s. At 56 TH/s, its share is meaningful for fleet production at current difficulty. the network recalibrates mining difficulty approximately every 14 days to maintain ten minute block intervals. Investment math for the Whatsminer M21S:… hardware acquisition plus $5.64 daily power over your deployment timeline. At 56 TH/s, the Bitcoin produced must exceed that total for positive returns. 155 x 240 x 390mm at 12.5 kg. 100-240V input. Ethernet connectivity. 5 - 45 °C operating range. MicroBT firmware for pool configuration. Pool compatible with F2Pool, Foundry, AntPool, ViaBTC, and every other SHA 256 Stratum pool. Daily electricity $5.64 at $0.07 per kWh. Monthly: $169. The Whatsminer M21S competes against the full Bitcoin network hashrate of 600+ EH/s. At 56 TH/s, its share is meaningful for fleet production at current difficulty. the network recalibrates mining difficulty approximately every 14 days to maintain ten minute block intervals.
