US ETF Flow Update: May 18 brought some interesting divergence across the board. Spot BTC and ETH ETFs saw net outflows, while SOL and XRP funds bucked the trend with positive inflows. Here's the breakdown: BTC: -$648.64M ETH: -$86.31M SOL: +$2.06M XRP: +$750.44K A clear rotation happening. While the big two face selling pressure, capital is quietly shifting into alt-focused ETFs. SOL leading the small-cap charge, with XRP also seeing modest demand. Not advice, but worth watching if you track institutional sentiment. The flows tell a story.
