The Antminer S19 model belongs to the latest generation of ASIC devices for mining cryptocurrencies. Thanks to the implementation of the latest technologies, it stands out favorably against its predecessors with improved efficiency and extended service life.
Versatility.
The device uses the SHA-256 algorithm and is designed for mining such popular first-generation cryptocurrencies as VTS, VSN, LCC and others.
High hashing speed.
The Antminer S19 miner provides one of the best hashing speeds in the industry – 95 ± 3% TH/sec.
Excellent energy efficiency.
The power consumption of the Antminer S19 is at the level of 3250 ± 5% W. The power supply is built-in. The ratio of electricity costs and computing work performed by this model is much better than that of its predecessors – only 34.5 ± 5% J / TON.
A specialized processor of the latest generation.
Devices of the Antminer S19 model are equipped with the latest specialized processor. This is a proprietary development of Bitmain Corporation. By optimizing the architecture of electronic circuits, it was possible to achieve an unprecedentedly low energy consumption coefficient – only 23 J/TH.

For miners, useful information and the required firmware can be changed or disabled the SSH port and change passwords. It puts into sleep mode a quiet start and very little noise that conventional systems give out. I don’t do mining, but according to the recommendations I see that the firmware is super and those who are in the subject took it to their service.

If you want to engage in mining, then you can predict the likely profit, since the contract implies a fixed hash rate. But keep in mind that other factors also affect the final income, there are also no limits on the use of cloud mining services, one person can conclude contracts with several companies at once. Another plus is that most projects allow you to mine different cryptocurrencies. This allows you to hedge the risks associated with falling rates;

In February last year, users of the social network Twitter, who are interested in the blockchain industry, saw the announcement of the new Bitmain Antminer S19 and S19 pro ASIC models https://miningasic.com/bitmain/firmware-for-antminer-s19/ . A device for professional Bitcoin mining has appeared, accelerating over 100 Th/s.
ASIC Antminer s19 pro 110 TH is really good. The second, slower model (95.00 Th/s) is also very attractive, especially due to the lower price.
