Grayscale Investments filed an application with the SEC on Tuesday to convert its hybrid crypto fund, which includes Bitcoin, Ethereum, Solana, XRP, and Avalanche, into an ETF. Grayscale's product, called the "Grayscale Digital Large Cap Fund," is currently traded over-the-counter with $524 million in assets under management, according to the company's website. The fund is made up mostly of Bitcoin (nearly 75 percent) and Ethereum (about 19 percent), with the remainder consisting of Solana, XRP and AVAX. The company has previously converted bitcoin and ethereum funds into ETFs, and Grayscale's converted spot bitcoin ETF, which began trading in January, has around $14 billion in assets under management.
