[Bitcoin Falls to $64,000, Crypto Market Declines Across the Board] According to CoinDesk, Bitcoin retreated to $64,000 after hitting a monthly high of $65,500 on Wednesday, as profit-taking combined with Iran's attack on a U.S. Gulf military base triggered a broad decline in the crypto market. Since 8:00 AM UTC+8, BTC and ETH have dropped by 1.1% and 1.7%, respectively, with bearish sentiment dominating the price movements of most tokens. The negative cumulative trading volume difference indicates active selling pressure in the market. In derivatives, XRP futures open interest surged to a 10-day high of 2.21 billion tokens, coupled with price declines, signaling a rise in bearish sentiment. MORPHO bucked the trend, rising 3.5% to challenge the $2.20 resistance level. Bitcoin's 30-day implied volatility index increased by 2% to 38%, while call option positions in the Deribit options market for the $70,000 to $72,000 range grew, reflecting some traders betting on a price rebound by the end of July.
