Bitcoin held above $64,700 and Ethereum stayed near $1,870 as institutional demand returned through spot ETF inflows. BTC gained 1.15% to $64,712 on $11.1B volume, while ETH added 1.35% to $1,869 on $6.1B volume. The clearest catalyst was $132.3 million in net inflows to US spot Bitcoin ETFs on July 17, led by BlackRock's IBIT with $136.5 million. That flow pattern matters because it signals sustained institutional accumulation after a sharp $424.7 million outflow on July 13.
