Green United’s founder, Will Thurston (who, along with promoter Kristoffer Krohn, is also named as a defendant in the lawsuit), allegedly used the money investors gave him for the phony Green Boxes and used it to buy S9 Antminers – commercially-available bitcoin mining machines – which he then used to mine bitcoin for himself. According to the SEC, investors didn’t see any of the actual bitcoin (BTC) their purchases mined, but instead received periodic distributions of worthless GREEN tokens created by Thurston on the Ethereum blockchain.
