币界网报道：Bloomberg analysts have significantly increased their approval odds for spot altcoin ETFs to 90% or higher following recent SEC engagement, with Eric Balchunas and James Seyffart citing the regulator's interactions as a positive signal. The updated projections now include XRP, Dogecoin, Cardano, Litecoin, Solana, Polkadot, and Avalanche ETFs potentially gaining approval by 2025. This shift comes weeks after the analysts had assigned sub-90% likelihoods to some proposals. The SEC under new chairman Paul Atkins has shown a more digital asset-friendly stance, recently requesting updated filings for spot Solana ETFs—a move interpreted as progress toward near-term approvals. While only Bitcoin and Ethereum spot ETFs have been approved to date, these products have already attracted billions in investment by allowing crypto price exposure without direct asset ownership.
