The measures taken by #实用交易工具 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 crypto benchmark index signifies that these altcoins are advancing into the mainstream financial sector, which can attract more attention from traditional investors. If approved by the U.S. SEC, the Hashdex ETF could invest in these currencies, further increasing their liquidity and market depth, lowering investment thresholds, and enhancing accessibility. For 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.
