BlackRock has acquired 768,671 BTC, accounting for 3.66% of the total Bitcoin supply, through its iShares Bitcoin Trust as of September 2025. This significant acquisition marks a pivotal moment in institutional adoption of cryptocurrency, potentially influencing Bitcoin's market dynamics and signaling broader acceptance within traditional finance sectors. The move has garnered attention for its potential impact on Bitcoin's liquidity and volatility. Analysts have noted that this could lead to tighter bid-offer spreads and a shift in global perception of the asset, as institutional players increasingly participate in the cryptocurrency market.
