At the end of February 2020, Bitmain announced a new generation of its Bitcoin mining asic miners called Antminer S19 and S19 PRO. It is worth noting that the S19 Pro model for the first time for Bitmain exceeded the hashrate on the SHA-256 algorithm at 100TH/s and amounted to 110TH/s at 3250W. With such indicators, this model is currently the most energy efficient on the market with an indicator of 29.5 J/TH. The manufacturer set the price of the new product at a significant 20.770 yuan or almost 3000 USD, despite the recent strong drawdown in the price of Bitcoin cryptocurrency. But despite this, the first batch of S19 Pro has already been sold out. A simpler version of S19 (95TH/s, 3250W and 34.5J/TH) costs 15.495 yuan or 2200USD and is still available for order on the Chinese version of the company's website. If you count on the Profit-mine.com website, the payback of new Bitmain ASICs will be about 400 days for both models at an electricity price of 0.05USD/kWh.
