BlackRock bought more than $900 million worth of Bitcoin over five days, according to the provided content. The buying was described as helping drive inflows into Bitcoin ETF products and intensifying concerns about a supply shock, a market condition in which available Bitcoin becomes harder to obtain as demand rises. In crypto markets, sustained institutional buying through exchange-traded funds can tighten circulating supply because fund issuers typically acquire the underlying asset to back investor demand.
