According to Foresight News, Rob Marrocco, Vice President and Global Head of ETF Listing at Cboe, believes that crypto ETFs other than Bitcoin and Ethereum are unlikely to appear until the market and regulatory environment change. The market's expectations for Solana and XRP spot ETFs are unrealistic in the short term because these cryptocurrencies do not have a futures market, which is the main factor in approving Bitcoin and Ethereum spot ETFs. He added that this means that the only feasible way to bring the Solana ETF to market is to first pass the Solana futures ETF and then pave the way for the spot ETF.
