Altcoins have experienced their first rotation since January, signaling a shift in market dynamics. However, this momentum is under threat as the decentralized finance (DeFi) sector faces significant challenges. According to Bitfinex, DeFi has seen $292 million in outflows, contributing to a $14 billion drop in total value locked (TVL). These developments highlight potential vulnerabilities in the altcoin market, as the DeFi sector's performance is often closely linked to altcoin valuations. The substantial outflows and TVL reduction could impact investor confidence and market stability moving forward.
