最新报道:Bitcoin held above $113,600 amid cautious trading as investors awaited Fed Chair Powell's Jackson Hole speech for September rate cut signals. Solana and Dogecoin led major cryptocurrencies with 4% gains, while XRP, BNB, ETH, and TRX saw modest 1-3% increases. Market sentiment deteriorated sharply, with the fear and greed index dropping to 44 from 75 just six days prior. Analysts warn a break below $108,000 could trigger a slide toward $100,000, citing weakened momentum and on-chain data showing short-term holders selling at a loss. Powell's comments are expected to drive significant volatility, with dovish signals potentially sparking relief rallies.
