Institutional Bitcoin buying has sharply declined in 2025, according to data from CryptoQuant, raising concerns about a potential bear market. The reduced activity from major investors, often seen as market influencers, suggests growing uncertainty and the possibility of a price correction or prolonged downturn. This decline follows a strong rally earlier in the year, indicating a possible structural shift in market sentiment. Analysts suggest that the hesitation among institutional investors could reflect expectations of lower Bitcoin prices, increased regulatory risks, or a strategic wait for more favorable entry points. This trend serves as a cautionary signal for retail investors, emphasizing the importance of careful investment strategies and portfolio diversification.
