US exchange-traded funds tied to Ethereum, XRP, and Solana attracted almost $59 million on Sept. 9, while Bitcoin products lost $120.24 million, underscoring a selective institutional rotation that has not translated into a broad altcoin season. BlockchainCenter’s Altcoin Season Index remained at 37, far below the 75 threshold needed for an altseason, while Bitcoin’s market dominance has stayed broadly stable at 56.64%.
That narrow pattern continued into Sept. 11. XRP ETFs recorded $5.14 million of inflows, standing alone as positive while Bitcoin funds saw $282 million in withdrawals, Ethereum products lost $29.76 million, and Solana ETFs posted outflows of $482,000. Crypto analyst Xaif Crypto highlighted the divergence: “XRP ETFs just did something BTC, ETH and SOL couldn't today.”
Over the 30 days through Sept. 9, Bitcoin ETFs still dominated with $3.42 billion in net inflows, while Ether attracted $1.76 billion. Solana and XRP added $200.88 million and $185.32 million, respectively. Together, those four assets accounted for about $5.57 billion of roughly $5.64 billion in total net inflows across completed spot crypto ETF categories tracked by SoSoValue. Smaller fund categories remained largely dormant: Hyperliquid recorded $54.77 million, Chainlink $19.21 million, Hedera $2.54 million, and Avalanche $1.3 million, while Dogecoin, Litecoin and BNB registered small net outflows and Polkadot recorded no net flow.
Assets under management show an even wider divide. Bitcoin and Ethereum products held $99.33 billion and $15.69 billion, respectively, while XRP and Solana had grown to roughly $1.5 billion each. Hyperliquid, the next-largest category, held about $464 million, Chainlink stood below $182 million, and every other completed category was below $60 million. This hierarchy suggests institutional portfolios can rotate among Bitcoin, Ethereum, XRP and Solana without capital cascading into smaller crypto assets.
For XRP, the positive ETF flow coincided with a stable technical position. XRP traded near $1.35490 on Bitstamp, up 1.59%, holding above lower Bollinger Band support at $1.31373, with the band midpoint at $1.40574 as nearest resistance and the upper band near $1.49776. The Relative Strength Index was 52.57, indicating neutral momentum rather than overbought or oversold conditions.
