BlockBeats news, on May 19, Bitcoin volatility slightly rebounded to 1.90%, maintaining an upward trend for four consecutive days. High Bitcoin volatility is often associated with speculative trading and retail investor FOMO sentiment. When volatility decreases, it may indicate a reduction in short-term speculators, and the market enters a consolidation phase or a "cooling period." Additionally, Bitcoin price fluctuations are often linked to macroeconomic events, such as inflation expectations, interest rate changes, or geopolitical risks. When these external factors stabilize, Bitcoin's volatility may decrease accordingly.
