New miners from the Chinese manufacturer Bitmain Antminer S19 are also presented on the official website https://www.bitmain.com. ASIK 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.

Device comparisons

The Bitmain Antminer S19 line took the honorable first place among digital gold mining machines, displacing its predecessors S17 (67 TH / s) and T17 (with 55 TH / s).
