U.S. regulators are considering a groundbreaking request to list the first ETF holding a mix of cryptocurrencies, including altcoins. Grayscale's Digital Large Cap Fund (GDLC) could soon be available on NYSE Arca, pending SEC approval. This fund, created in 2018, includes Bitcoin, Ether, Solana, Avalanche, and XRP, managing $534 million in assets. If approved, it would be the first multi-crypto asset ETF on a national securities exchange. The SEC has 240 days to decide, with Grayscale facing competition from other proposed funds focusing mainly on Bitcoin and Ether.
