币界网报道:The US SEC received 72 applications for altcoin ETFs, including Solana, XRP and other assets. Analysts estimate that the probability of approval is over 90%. Bitcoin ETFs attracted $107 billion a year, and the continuous inflow of institutional funds promoted market compliance. Altcoin ETFs may start a staking income model, but the scale is expected to be less than 1% of Bitcoin. Fee wars and operational complexity will become the main challenges for issuers.
