$SOL Bloomberg analyst James Seyffart said that based on current precedent and demand, the SOL ETF could be approved in a few years after obtaining a CFTC-regulated futures market. Market structure bills such as FIT21 could accelerate this process. However, the SEC has made it clear that Solana is a security, which could make its ETF road very bumpy. In addition to Bitcoin and Ethereum, the SOL ETF has the greatest demand, and there is no demand for the LTC ETF, and it is not sure about DOGE. The SEC still decides the approval of all ETFs and will not approve digital asset ETFs that do not have federally regulated trading venues.
