As the US government takes a more open stance towards cryptocurrencies and the regulatory environment becomes clearer, asset management firms have begun launching exchange-traded funds (ETFs) focused on Bitcoin, Ethereum, and other digital assets. The approval of spot ETFs for Bitcoin and Ethereum has attracted significant institutional capital, accelerating the integration of cryptocurrencies into traditional finance. In the future, ETFs for altcoins like Solana, XRP, and Litecoin are also likely to receive approval, further expanding the presence of crypto assets in mainstream markets. While ETFs related to meme coins and NFTs are less likely to gain approval in the near term, their applications reflect the growing diversification in the broader crypto ecosystem.
