Just start the altcoin season and they will be in a total loss
Maybe they are rich but they are jot the only rich people on crypto space. In my opinion, I know they holding massive bitcoin but there is no logical reason to hoard it and pull it down to drive the price of their stock up. Also if they did, no one can stop them ad bitcoin itself is a decentralized asset where any holder can do on their portfolio. If they wanted to dump whatever millions worth they have they are feel free to do it.
