Bitcoin's net inflow to centralized exchanges (CEX) surged to 9,905 BTC on April 29, marking the largest single-day inflow in the past month, according to CryptoQuant analyst Woominkyu. This influx has hindered Bitcoin's ability to break through resistance levels. The Exchange Whale Ratio, which measures the proportion of large transactions, spiked to 0.707 on April 27, indicating that the top 10 inflow transactions accounted for over 70% of total deposits. This suggests that large holders are actively moving tokens to CEXs, potentially preparing for a sell-off. The increase in whale-dominated inflows and rising CEX reserves could signal that smart money is positioning to sell at higher levels, raising the possibility of a retest of the $74,000–$75,000 support zone if the inflow is not quickly absorbed.
