A social media post states that BlackRock sold more than $1 billion worth of Bitcoin over the past week. The source text does not include supporting evidence such as regulatory filings, fund flow data, blockchain records, or a statement from BlackRock, so the claim remains unverified based on the provided material alone. In crypto markets, reports of large Bitcoin sales by major asset managers can draw attention because institutional flows often influence sentiment and spot ETF positioning, but no further factual detail is supplied here.
