最新报道:The SEC has withdrawn 19b-4 filings for multiple altcoin ETFs including Solana, XRP, Cardano, and Ethereum staking products, halting anticipated expansion beyond Bitcoin ETFs. Regulators cited investor protection and market surveillance concerns, reflecting ongoing uncertainty over whether these tokens qualify as securities. While XRP trades at $2.17 with technical resistance near $3.00, the withdrawal limits institutional access to altcoins, favoring Bitcoin and Ethereum ETFs until clearer regulations emerge.
