The measures proposed by #鲍威尔发言 are likely to increase the attention and accessibility of altcoins among traditional investors. As a well-known trading platform, Nasdaq's proposal to include XRP, SOL, ADA, and XLM in the cryptocurrency benchmark index signifies these altcoins' advancement into the mainstream financial sector, potentially attracting more attention from traditional investors. If approved by the SEC, the Hashdex ETF could invest in these cryptocurrencies, further increasing their liquidity and market depth, lowering the investment threshold, and enhancing accessibility. In terms of portfolio strategy, if approved, it may be worth considering an appropriate allocation to these altcoins for diversified returns, but one must be mindful of their high volatility and regulatory uncertainty.
