The measures indicated by #纳斯达克加密ETF扩容 are likely to increase the attention and accessibility of altcoins among traditional investors. As a well-known trading platform, Nasdaq's proposal to include cryptocurrencies like XRP, SOL, ADA, and XLM in its crypto benchmark index signifies that these altcoins are making strides towards mainstream finance, potentially attracting more traditional investors. If approved by the SEC, the Hashdex ETF could invest in these currencies, further enhancing their liquidity and market depth, lowering investment barriers, and improving accessibility. For portfolio strategies, if approved, a suitable allocation of these altcoins could be considered for diversified returns, but attention must be paid to their high volatility and regulatory uncertainty.
