Recently, the U.S. Securities and Exchange Commission (SEC) officially approved the Hashdex Nasdaq Cryptocurrency ETF, which covers a variety of mainstream digital assets including Bitcoin (BTC), Ethereum (ETH), Ripple (XRP), Solana (SOL) and Stellar (XLM). This decision is not only seen as an important signal that the regulation of the U.S. crypto market is gradually becoming clearer, but also brings new diversified investment channels for institutional and retail investors.
