According to Odaily Planet Daily, Rob Marrocco, vice president and global head of ETF listings at Cboe, believes that crypto ETFs other than Bitcoin and Ethereum are unlikely to appear until the market and regulatory environment change. Marrocco said in the ETF Store podcast on June 11 that the market's expectations for Solana and XRP spot ETFs are unrealistic in the short term because these cryptocurrencies have no 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 a Solana ETF to the market is to first go through a Solana futures ETF and then pave the way for a spot ETF. Marocco further claimed that even if a Solana futures ETF is introduced, they will need to trade for a long time to establish a good track record. However, this process may take quite some time to bear fruit.
