CryptoQuant analysis shows that the total inflow of Binance BTC Whale on the 30th was 3.9 billion US dollars, a decrease of 44.3% from the peak of 7 billion US dollars on June 12th; The inflow of retail investors was 7.8 billion US dollars, a decrease of 22% from 10 billion US dollars on June 5th. The inflow of retail investors was about twice that of the whale, with a gap of 3.9 billion US dollars. This divergence coincides with the eve of the Federal Reserve's FOMC meeting on July 28-29, with a probability of a 25 basis point rate hike in federal funds futures pricing at around 36%, and a more likely scenario of maintaining the target range of 3.50-3.75% unchanged. The unexpected interest rate increase may support the yield of USD and treasury bond bonds and increase the volatility of risky assets. If the suspension of interest rate increase is accompanied by the dove guidance, it may alleviate the macro pressure.
