Well GS did have HUGE short positions on pretty much everything going into 2017 and it's not really like him to make a literal fuckton of loosing bets. Seriously, if you look at his hedge funds's historical records it's like he was either psychic or manipulating things or had help manipulating things. (we now know witch one of those it was)
So yeah it sure looks like there were big plans to crash things then scoop up the winnings from the shorts. And I don't know what after that.
