Cryptocurrency Miners Tech and Which Mining Machines are Profitable?

Bitmain will launch its next-generation 7nm ASIC chip, BM1397, which achieves will improve performance, chip area and energy efficiency for mining cryptocurrencies such as Bitcoin (BTC) and Bitcoin Cash (BCH), that use the SHA256 algorithm for their Proof of Work (PoW). It needs less lower power and can offer an energy consumption to computing ratio as low as 30J/TH. This is a 28.6 percent improvement in power efficiency in comparison with Bitmain’s previous 7nm chip, the BM1391. Bitmain’s engineering team has thoroughly customized the chip design to optimize its architecture, circuit and economics. Bitmain had been the dominant cryptocurrency miner for several years.

Obelisk SC1 Immersion

The SC1 Immersion miner is designed for use in liquid immersion tanks, such as those from Green Revolution Cooling, Midas Green Technologies,, and E3 NV. It contains 4 hashing boards, 1 control board, 2 power supplies, and all required cables.


The mastermind behind Bitmain’s breakthrough S7 and S9 chips was Yang Zuoxing, a nuclear physics major-turned chip designer. Yang helped Bitmain develop its market-leading technologies during his year-long service as a part-time contractor. Yang quit Bitmain in June 2016 when they would not offer him significant shares. He started his own mining gear start-up called MicroBT. MicroBT’s Whatsminer M10 are now among many new mining rigs with better power efficiencies than the Bitmain S9. In September, 2018, the M10 Whatsminer began shipping. The M10 runs on 16nm ASIC chips while delivering a very efficient 65W/TH hashing power. The miner produces 30-33TH/s at 2150W and has a 2500W PSU mounted on top that is fully enclosed.

Which Crypto Mining Machines are Profitable Now? has real-time estimates of the profitability of different mining gear. Currently the most profitable is the Obelisk SC1 Immersion. The soon to be released Bitmain Antminer Z11 is estimated to have $13.89 per day profitability. Obelisk SC1 Immersion is estimated at $34.52 per day profitability.
