Little known fact … he/they (the Ccp wife) have insane amounts of convertible options in the FB stock. A while back they were converting $2 million EVERY DAY. I didnt believe it at first so I dug in and looked up every single SEC filing they had made going back 4 months. Sure enough, every single day, they converted the max amount they were allowed by law. I quit following it in disgust when I learned they spent $400 million on election interference measures, and NO ONE stopped them. Likely that is where the $ came from … and likely there is way way more we dont know about.
