“If sufficient worry builds, customers rush to exit, creating extra SNX promote strain and feeding a cascading loop,” Thakur warned final week.
Thakur famous how the “liquidity is skinny,” AMM swimming pools are “closely sUSD-weighted,” and “small strikes trigger outsized value swings.”
In the meantime, Warwick mentioned sUSD’s present instability is short-term, claiming that, “I’m truly not apprehensive about Synthetix for the primary time in years, which is why I’ve been shopping for SNX this 12 months.”
Regardless of his optimism, he warned holders, “It will be horrible to get shaken out right here. I’m not saying that is the underside—it very possible will worsen earlier than it will get higher.”
