Antminer S19 for Sale
The Antminer S19 is the Bitmain generation before the S21, and many are still mining today. It comes in many versions: the S19 and S19 Pro, the S19j and S19j Pro, the S19k Pro, the S19 XP and the hydro-cooled S19 Pro Hyd and S19 XP Hyd. Hashrates range from under 100 TH/s on the first S19 models to more than 250 TH/s on the S19 XP Hyd.
Most S19 versions sit between about 21 and 34 J/TH, so they use more power per terahash than an S21 but usually cost less to buy. That trade works best where power is cheap. Check the listing title for the exact version, hashrate and power draw, compare the price per TH/s on the Miner Price Index, and run the model through the mining calculator with your electricity rate.

Questions
Which S19 version is the most efficient?
The S19 XP and S19 XP Hyd, at about 21 to 23 J/TH, with the S19k Pro close behind at about 23 J/TH. The S19 Pro and S19j Pro sit near 30 J/TH, and the original S19 uses the most power per terahash. The best buy weighs that against the price per TH/s and your power cost.
Is an S19 still worth buying?
It can be, where power is cheap: an S19 costs less than an S21 but uses more electricity for each terahash. Whether it earns more than it costs depends on the Bitcoin price, the network hashrate and your power rate, so check the model in the mining calculator first.
