TechFlame news, on October 21, CryptoQuant published an analysis showing that Binance's Bitcoin net flow index recently showed significant negative values, and the 30-day moving average (SMA30) data showed that Bitcoin was leaving the exchange in large numbers. Analysts pointed out that this phenomenon indicates that investors prefer to hold rather than sell, usually in line with the accumulation phase in the market cycle. Although daily data fluctuates greatly, the 30-day average trend clearly points to cumulative behavior, which may indicate increased market confidence. Experts believe that current trends may support Bitcoin's short-term bullish trend.
