Grayscale is making moves to list an exchange-traded fund (ETF) featuring a mix of spot cryptocurrencies. On April 1, the asset manager filed with the US SEC to convert its Digital Large Cap Fund into an ETF. This fund, launched in 2018, includes Bitcoin, Ether, Solana, XRP, and Cardano, boasting over $600 million in assets. Currently, it's only accessible to accredited investors. The filing follows NYSE Arca's October request to list the fund, highlighting the growing interest in crypto index ETFs as regulatory attitudes soften. Industry experts see index ETFs as a logical next step for crypto investments.
