Binance’s recent margin update has sparked a sharp sell-off, particularly impacting the Solana meme coin ACT. The update resulted in a dramatic 50% price drop within a short timeframe, triggering liquidations and drawing criticism from traders and industry experts for its sudden implementation with limited notice. The impact was significant, with ACT experiencing the most severe losses among other affected altcoins. While market participants initially speculated on potential sell-offs driven by large orders triggered increased spot trading volume, trader skepticism remains high regarding the role of Wintermute in potentially initiating the recent sell-off. Binance’s decision to adjust margin and leverage tiers for specific tokens has left traders scrambling to adjust their positions in a short window, leading to widespread liquidations and losses across various altcoin markets.
