S21 miner delivery start
Company: CleanSpark
What the later record shows
Outcome not yet confirmed
Later passages describe an April 2024 amendment and option exercise for S21 Pro units, with delivery 'through the remainder of calendar 2024'. None confirms that deliveries under this agreement began in April 2024.
“we modified our option contract for the purchase of 100,000 Antminer S21 miners to include the Antminer S21 Pro ("S21 Pros") miners and executed the full purchase with delivery to occur through the remainder of calendar 2024”
