随着AI疑虑重回市场，比特币跌破82,000美元，DeFi代币领跌

Digital assets experienced a sharp downturn as Bitcoin dropped roughly 2.9% to touch $81,600 during early trading sessions. The downward momentum was largely catalyzed by a concurrent slide in Nasdaq futures, highlighting the continued correlation between risk-on technology stocks and cryptocurrencies. Decentralized finance assets bore the brunt of the selling pressure, as evidenced by a 6% plunge in the dedicated DeFi sector index. Broader market indicators like the CoinDesk 80 also registered notable declines of about 3.5% as investors reassessed valuations. Analysts note that lingering skepticism over near-term artificial intelligence monetization has begun to weigh on overall market sentiment. This macro-driven risk aversion could lead to heightened volatility across digital asset markets in the upcoming sessions.
