Solana and Hyperliquid ETFs now account for nearly 80% of altcoin ETF trading volume, according to The Block. The Solana ETF has amassed $904 million in assets under management, while the Hyperliquid ETF, launched just two months ago, has already attracted $350 million in net inflows. Both ETFs represent approximately 2% of their respective token's market cap. In contrast, Bitcoin ETFs account for about 9% of Bitcoin's market cap, indicating potential growth opportunities for altcoin ETFs. Solana and Hyperliquid ETFs appeal to investors with higher risk tolerance, while Bitcoin and Ethereum ETFs attract a more stable investor base. As these altcoin ETFs engage with regulators and expand their infrastructure, they may attract a broader range of investors.
