Did CEX misappropriate user $WLFI funds for a sell-off? Possibly, otherwise there wouldn't have been rumors and the addresses wouldn't have been frozen, but the investigation is ongoing.
A normal person would have just used contract hedging. If they directly used user assets to lock in profits, even saving on funding fees, while shrewd, it's a bit tricky.
Shortly speaking, since the funds will be unlocked in the future anyway, there shouldn't be a big problem if there's no run. More broadly, how did FTX crash in the first place? It was also user funds misappropriated, but $WLFI didn't have that much influence.
As for whether Brother Sun's hundreds of millions of coins could crash $WLFI? Not necessarily; there are definitely other whales involved. But who caused the crash isn't important right now; having someone to blame is enough.
But since Brother Sun's address was frozen, $WLFI has taken off. Now it's like a pile of mud on your pants, nothing more than shit.
