Bitmain opens sales for the Antminer S19 series, delivering 95-110 TH/s with dramatically improved energy efficiency. Both models sold out in under 24 hours, with first shipments scheduled for May 11 — the exact date of Bitcoin's third halving.
The S19 series powered the mining industry through the institutional adoption era, the 2021 bull run, and China's mining ban. The timing of its launch — right as COVID crashed markets and just before the halving — made it one of the most consequential miner releases in Bitcoin history.
