BlackRock has rapidly increased its Bitcoin holdings, now owning nearly 350,000 BTC, making it the third-largest holder worldwide after Satoshi Nakamoto and Binance. This achievement highlights BlackRock's expanding role in the cryptocurrency market, fueled by the success of its iShares Bitcoin Trust and a surge in institutional interest. CEO Larry Fink, who previously criticized Bitcoin, now views it as a transformative global asset. BlackRock's growing Bitcoin reserves reflect a significant shift in its approach to digital currencies.
