BlackRock, the world's largest asset manager, has sold 749 Bitcoin valued at approximately $88 million on October 29, reducing its total holdings to 805,540 BTC, worth around $89.12 billion. This sale comes amid a broader decline in the cryptocurrency market, with Bitcoin and other major cryptocurrencies experiencing losses. Spot Bitcoin ETFs saw daily outflows of 4,238 BTC, equivalent to $471 million, although they have added 40,004 BTC, or $4.48 billion, this month.
