最新报道:Bloomberg ETF analyst Eric Balchunas has raised his approval odds for spot altcoin ETFs to 100% following the SEC's adoption of generic listing standards that eliminated 19b-4 filing requirements. The regulator instructed issuers to withdraw filings for ETFs tracking Solana, XRP, Cardano, Litecoin, and Dogecoin, with only S-1 registration statements remaining for approval. This streamlining comes amid increased ETF filings targeting various cryptocurrencies, though SEC Commissioner Caroline Crenshaw warned these "nascent and untested" products carry unique risks from unregulated spot markets.
