币界网报道：On July 1, Eric Balchunas, senior ETF analyst at Bloomberg, posted on social media that "REX-Osprey's SOL spot ETF (SSK) will be officially launched on Wednesday this week. This will be the first ETF in the United States that allows pledges. 40% of the ETF's assets will be held in the form of "securities" through other Sol-related ETPs (to meet the compliance requirements of the 1940 Act). The management fee is 0.75%, but due to the use of a Class C corporate structure, the total fee will reach 1.28% after tax expenses are included. Although this is a new product launch worthy of attention, it is also necessary to look at it rationally and manage expectations. SOLZ (Solana Futures ETF) has an asset size of only US$22 million three months after its listing, which is not ideal, especially in the context of SOL's 15% increase. If there is a choice, investors generally prefer 100% spot products under the Securities Act of 1933, but there is currently no clear launch time for these products. Compared with the Bitcoin spot ETF, the asset size of SOLZ (Solana Futures ETF) is only US$22 million, which is not ideal, especially in the context of SOL's 15% increase. If there is a choice, investors generally prefer 100% spot products under the Securities Act of 1933, but there is currently no clear launch time for these products. Unlike Solana, there has not yet been a “fee war” for Solana-related ETFs, and no big companies like BlackRock and Fidelity have participated.”
