Recent ETF data reveals a shift in investor behavior, with SOL and XRP spot ETFs recording positive inflows last week, while BTC and ETH spot ETFs experienced significant net outflows. Bitcoin ETFs saw $359.91 million in outflows, and Ethereum ETFs faced $161.15 million in withdrawals, indicating a reduced short-term appetite for these major cryptocurrencies. In contrast, Solana-based ETFs attracted $13.17 million, and XRP ETFs gained $7.65 million in net inflows. This suggests a growing interest in alternative crypto investments as investors diversify away from Bitcoin and Ethereum. The inflows into SOL and XRP highlight increasing institutional confidence in these networks, with Solana's high-speed blockchain and XRP's role in cross-border payments drawing attention. The divergence in ETF flows may reflect a short-term rotation rather than a long-term trend, as investors adjust their portfolios based on market conditions and risk appetite. Continued inflows into altcoin ETFs could lead to expanded offerings, while sustained outflows from Bitcoin and Ethereum ETFs might temporarily pressure their prices.
