Solana ETF: A New Frontier in Crypto Investing
The launch of the first Solana-based ETF marks a pivotal moment for altcoin adoption in traditional finance.

Regulatory and Global Developments
SEC Delays Decision on Polkadot ETF
The U.S. Securities and Exchange Commission (SEC) has postponed its decision on 21Shares’ spot Polkadot ETF, extending the review period. This follows a pattern of cautious regulatory oversight, though approval expectations remain high for later in 2025.
Bitwise Files Revised S-1 for DOGE and Aptos ETFs
Bitwise has submitted updated registration documents for potential spot Dogecoin (DOGE) and Aptos (APT) ETFs, signaling continued innovation beyond the top two cryptocurrencies.
Hester Peirce: In-Kind Redemption “Imminent”
SEC Commissioner Hester Peirce suggested that in-kind creation and redemption for crypto ETFs may be “on the horizon,” a move that could reduce market impact and improve efficiency—long seen as a critical upgrade for institutional adoption.
International Expansion: Asia Embraces Crypto ETFs
South Korea Moves Toward Digital Asset ETFs
Democratic Party lawmaker Min Byung-deuk introduced a bill to amend South Korea’s Capital Markets Act, proposing to include digital assets as eligible underlying assets for ETFs. If passed, this would allow regulated financial institutions to offer Bitcoin and other crypto-backed investment products—aligning with President Lee Jae-myung’s pro-digital asset agenda.
Hong Kong Greenlights Virtual Asset ETF Services
Caifu Securities’ subsidiary, Caifu Hong Kong, has received approval to offer customer trading services for virtual asset ETFs. This positions Hong Kong as a growing hub for institutional crypto investment in Asia, competing with established markets like the U.S. and Europe.

Frequently Asked Questions (FAQ)
Q: What is a spot crypto ETF?
A: A spot crypto ETF directly holds the underlying cryptocurrency (e.g., Bitcoin or Ethereum) rather than futures contracts or derivatives. This provides investors with direct exposure to price movements of the actual asset.
Q: Why did Bitcoin ETFs see outflows after 15 days of inflows?
A: Short-term outflows can result from profit-taking, portfolio rebalancing by large investors, or shifts toward other assets like Ethereum or emerging altcoins. They don’t necessarily indicate a bearish trend if weekly or monthly inflows remain positive.
Q: How do Ethereum ETFs compare to Bitcoin ETFs in performance?
A: While Bitcoin ETFs dominate in total assets and daily volume, Ethereum ETFs have shown stronger consistency in recent weeks with fewer outflow days and broader participation across issuers like Fidelity and BlackRock.
Q: When will Solana ETFs be widely available?
A: The REX-OSPREY Solana staking ETF is already trading. Grayscale and other major players are progressing through the SEC review process, suggesting wider availability could occur by late 2025 or early 2026.
Q: What is in-kind redemption and why does it matter?
A: In-kind redemption allows authorized participants to exchange ETF shares for the underlying crypto assets instead of cash. This reduces market sell pressure during redemptions and lowers costs—making ETFs more efficient and attractive to institutions.
Q: Are there risks in investing in new crypto ETFs like DOGE or Aptos?
A: Yes. While innovation drives growth, newer assets like Dogecoin and Aptos carry higher volatility and regulatory uncertainty compared to Bitcoin or Ethereum. Investors should assess risk tolerance before exposure.
