$USDC The measures taken by $USDC are very 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 that these altcoins are making their way into the mainstream financial sector, which can attract more traditional investors' attention. If approved by the SEC, the Hashdex ETF could invest in these cryptocurrencies, further increasing their liquidity and market depth, lowering investment thresholds, and enhancing accessibility. For portfolio strategies, if approved, it may be considered appropriate to allocate these altcoins for diversified returns, but one must be mindful of their high volatility and regulatory uncertainty.
