With the SEC (SEC) placing more emphasis on cryptocurrencies and new spot altcoin ETFs likely to launch in the coming months, these approvals could open up some attractive long-short strategies, according to digital asset brokerage and research firm K33. Eight issuers have already submitted applications for Solana spot ETFs, and the SEC is reaching out to these asset managers to ask them to include staking clauses in their updated applications. Vetle Lunde, head of research at K33, noted that this indicates increasing regulatory engagement and also increases the likelihood that staking will be part of Ethereum and Solana ETFs. Solana isn't alone — a variety of other underlying crypto assets have also submitted applications, including LTC, XRP, and DOGE. Meanwhile, on Wednesday, K33 launched a new private placement aimed at raising at least 85 million SEK ($8.9 million) for the purchase of bitcoin as part of its broader goal of acquiring 1,000 BTC ($105 million) for the company's finances. The move will unlock the company's operating leverage as a broker, improve margins, support new product launches, and enhance its ability to attract large institutional clients, the company said.
