BlackRock's spot Bitcoin ETF just witnessed a significant surge—pulling in $287 million in a single trading day, marking its strongest inflow in nearly three months. The move signals renewed institutional appetite for direct Bitcoin exposure through regulated financial vehicles. This kind of capital influx often precedes broader market movements, as major asset managers reassess their digital asset positioning. For traders and analysts monitoring on-chain flows, large ETF inflows like these can indicate shifting sentiment among traditional finance players entering the crypto space.
