According to market news, 21Shares has submitted a DOGE ETF application to Nasdaq.
Documents submitted by Nasdaq to the SEC indicate that Nasdaq plans to list the 21Shares Dogecoin ETF under rule 5711(d), with the trust managed by 21Shares US LLC and Coinbase Custody holding Dogecoin assets, tracking the DOGE-USD reference rate index published by CF Benchmarks.

According to Edaily, South Korea's ruling party, the People Power Party, announced seven new policies to cultivate the digital asset ecosystem, planning to open BTC and other spot ETF trading within the year and abolish the "1 Exchange - 1 Bank" restriction to promote institutional capital entry.

ETF Issuer Teucrium to Launch Inverse XRP ETF
According to CoinDesk, ETF issuer Teucrium announced plans to launch an inverse XRP ETF to allow investors to profit from a decline in XRP prices, pending demand assessment.
Additionally, Teucrium has launched the first XRP ETF in the US, the Teucrium 2x Long Daily XRP ETF, aimed at providing twice the daily return of XRP through swap agreements, referencing European exchange-traded products as the benchmark rate.
According to Bitcoin.com, asset management company Grayscale met with the SEC's crypto working group on April 21, applying for permission to stake its Ethereum ETF (ETHE and ETH). The company stated that due to regulatory restrictions, its managed assets of $8.1 billion have missed approximately $61 million in potential earnings since the product's launch until February 2025.
Grayscale presented three arguments:
1) Similar products in Europe and Canada have successfully implemented staking; 2) Staking can enhance the security of the Ethereum network; 3) A risk control plan has been developed, including a "liquidity reserve."
Coinbase Custody will provide technical support to mitigate forfeiture risks. Currently, US spot Ethereum exchange-traded products (ETPs) cannot fully reflect the underlying asset value due to the prohibition of staking. Grayscale calls on the SEC to update regulatory rules in reference to traditional financial products.
According to Cointelegraph, nearly 16 months after the launch of spot Bitcoin ETFs, Grayscale's GBTC continues to dominate in revenue generation, with implied annual revenue exceeding $268 million—this figure surpasses the total revenue of all other Bitcoin ETFs combined ($211 million).

Views and Analysis on Cryptocurrency ETFs
According to The Block, Bitwise Chief Investment Officer Matt Hougan stated that four major financial institutions—Merrill Lynch, Morgan Stanley, Wells Fargo, and UBS Group (managing over $10 trillion in client assets)—are expected to fully support Bitcoin ETF products by the end of this year.
Despite the inflow into Bitcoin ETFs being lower than the same period in 2024 (attracting only about $4 billion so far this year compared to $11.8 billion last year), Hougan still predicts a record net inflow for 2025.
He noted that institutional participation is on the rise—nine of the world's top ten hedge funds now hold Bitcoin, including institutional investors like Emory University and the Texas Teacher Retirement System, as well as large asset management companies like BlackRock entering the market, which will drive more investors into the Bitcoin market.
According to The Block, BlackRock's digital asset head Robert Mitchnick stated at the Token2049 event in Dubai that Bitcoin ETF funds are flowing in on a large scale, and the investor structure is shifting from retail to institutional.
Mitchnick pointed out that the initial phase of ETF launches was mainly participated in by retail clients, including high-net-worth individuals with holdings exceeding $100 million. However, the proportion of retail clients has gradually decreased each quarter, while the proportion of institutional and wealth management clients has been steadily increasing. Regarding altcoin ETFs, he mentioned that current market interest remains primarily focused on Bitcoin, as Bitcoin's properties as a portfolio hedge differ from other cryptocurrencies.
Matrixport: Bitcoin ETF and Futures Capital Flowing Back, Long-Term Holding Demand Rebounding
Matrixport released a chart today indicating that since March 19, Bitcoin ETF funds have been continuously flowing out, and the open interest in the futures market has also decreased. From January to April, the ETF saw cumulative net outflows of nearly $5 billion.
However, recently we have observed a large-scale inflow of nearly $3 billion, with an increase in open interest in futures. Interestingly, the funding rate remains at a low level.
This indicates that the current new capital inflow mainly comes from genuine long-term holding demand, compared to the ETF buying driven by arbitrage funds at the beginning of the year, with overall bullish signals being more positive.
According to data shared by Bloomberg analyst @JSeyff, several institutions have submitted applications for spot crypto ETFs for LTC, SOL, XRP, and others.
Bloomberg Intelligence estimates that the probability of approval for Litecoin, Solana, and crypto asset basket/index ETFs is 90%, while XRP is at 85%, DOGE and HBAR at 80%, and DOT, AVAX, ADA, etc., at 75%.
All projects' 19b-4 filings have been confirmed by the SEC, with final approval deadlines concentrated in the second half of 2025.
