The cryptocurrency sector is witnessing a wave of new exchange-traded fund (ETF) filings, with several proposals targeting altcoins. Canary Capital has filed a 19b-4 form for a Hedera (HBAR) ETF, while Bitwise has registered an Aptos ETF entity in Delaware. This follows the launch of Aptos-focused products in Europe, including the Bitwise Aptos Staking ETP and 21Shares Aptos Staking ETP. WisdomTree's spot XRP ETF proposal has been published in the Federal Register, initiating a 21-day public comment period, with the SEC review process potentially extending up to 240 days and a final decision deadline set for October 24. Grayscale has applied to convert its XRP Trust into an ETF and has received SEC acknowledgment for a Cardano fund. The range of filings now extends beyond Solana, XRP, and Litecoin to include Hedera, Aptos, and Polkadot. Grayscale has also filed for a Polkadot ETF, with the token currently holding a $6.7 billion market cap.
