U.S. spot bitcoin ETFs post $730.9M net inflows, biggest one-day haul since Jan. 14

U.S. spot bitcoin ETFs posted $730.9M in net inflows, the largest single-day intake since Jan 14, signaling a renewed wave of institutional demand via regulated vehicles. Such flow strength typically improves market depth and liquidity while tightening available spot supply through ETF creation activity. Near-term, this can support risk appetite across major crypto assets and reinforce BTC's role as the primary beta driver.
