Digital asset brokerage and research firm K33 stated that as the U.S. Securities and Exchange Commission (SEC) adopts a more favorable stance toward cryptocurrencies, new spot altcoin ETFs may be approved in the coming months, offering investors some compelling long and short strategy opportunities. Currently, eight institutions have submitted applications for spot Solana (SOL) ETFs. The SEC has proactively reached out to asset management firms, requesting that they include staking provisions in their updated filings, indicating increased regulatory engagement and raising the likelihood that Ethereum and Solana ETFs may feature staking capabilities. In addition to Solana, there are also ETF applications for other crypto assets such as LTC, XRP, and DOGE. (The Block)
