Antminer S19 Pro purchase from Bitmain
Company: Riot
What the later record shows
Delivered; the record does not say when
Riot received 34,608 S19-Pro miners during 2021. By year-end 2021, the only miners still to be delivered were S19j-Pro and S19XP units, so the S19-Pro orders were fulfilled. No passage says whether this particular 8,000-unit order arrived by April 30, 2021.
