What moved the market
- AI worries returned and Nasdaq futures fell, pulling Bitcoin lower. DeFi tokens led the decline, with the DeFi index down 6% in one report.
- Oil prices above $110 have revived bets that central banks may raise interest rates. Higher rate expectations can weigh on riskier assets like bitcoin.
- Bitcoin open interest fell 6.7% over 24 hours, which means fewer open positions in the market. Its 8-hour funding rate is slightly positive at 0.0027%.
- Sentiment remains in greed territory. The Fear and Greed Index is at 68 (Greed), up from 63 yesterday, even after the price drop.
