Overview of Last Week's Crypto ETF Dynamics
Bitcoin ETF and Treasury Companies Buy Large Amounts of $60,000 Protective Put Options
According to market news, large Bitcoin ETF holders and treasury companies have recently concentrated their purchases of BTC put options with a strike price of $60,000 or below, with terms of 6 months and 1 year on Deribit, as a hedge against prices falling below $60,000.
Deribit stated that the open interest for BTC put options with a strike price of $60,000 has risen to approximately $1.5 billion, the highest among all strike prices and terms on the platform, indicating a significant increase in demand for medium to long-term downside hedging. Currently, Bitcoin is fluctuating around $67,000, but the implied volatility for 30-day put options is about 7% higher than for call options, indicating that the market still prefers downside protection.
Q4 2025 Ethereum ETF Sees Significant Reduction, Harvard Endowment Fund is the Largest New Buyer This Season
According to Bloomberg ETF analyst James Seyffart, 13F filing institutions have overall reduced their holdings in Ethereum spot ETFs, with hedge funds concentrating their sales due to a collapse in basis trade returns; traditional/long-term funds are increasing their positions against the trend, with Harvard's endowment fund being the largest new buyer this season.
Nasdaq Applies to List VanEck JitoSOL ETF
According to Cointelegraph, Nasdaq has submitted a rule change proposal to list the VanEck JitoSOL ETF. This ETF will directly hold liquid staking tokens based on Solana, JitoSOL.
Brian Smith, chairman of the Jito Foundation, stated that if approved, staking rewards will not be distributed separately but will be reflected in the fund's net asset value. Since JitoSOL automatically compounds rewards, each token held by the trust will represent the underlying deposited SOL and its accumulated staking rewards on the Solana network.
Top University Endowment Funds, Including Harvard, Begin Allocating to Bitcoin ETFs
According to CoinDesk, facing declining expected returns from traditional assets, several university endowment funds are adjusting their investment strategies and beginning to allocate to cryptocurrency ETFs. Harvard University and Brown University have disclosed their holdings in Bitcoin and Ethereum ETF positions in their latest 13F filings.
Kim Lew, CEO of Columbia Investment Management Company, stated that the expected returns and alpha yields of traditional asset classes will be compressed, forcing institutions to move further along the risk curve and explore new strategies. Carlos Rangel of the W.K. Kellogg Foundation pointed out that if an 8% return cannot be achieved, the traditional foundation model will be difficult to sustain.
21Shares Spot SUI ETF Has Started Trading on Nasdaq
According to official news from the Sui Foundation, the spot SUI ETF issued by 21Shares (Nasdaq code: TSUI) has started trading on Nasdaq, providing US investors with regulated, high liquidity direct exposure to SUI through existing brokerage accounts.
This ETF has recently received approval from the US Securities and Exchange Commission.
iShares Applies to List Staked Ethereum Spot ETF ETHB, Intended for Trading on Nasdaq
US SEC filings show that BlackRock's iShares has submitted a revised S-1 to launch the "iShares Staked Ethereum Trust ETF" (code ETHB) and list it on Nasdaq.
This trust is a statutory trust under Texas law, primarily holding ETH, and will participate in Ethereum staking through third-party nodes like Coinbase to earn staking rewards, without affecting its tax qualification as a grantor trust, with approximately 70%-95% of its assets.
The product adopts a basket redemption mechanism of 40,000 shares, supporting cash or physical ETH redemptions, and only authorized participants can directly redeem with the trust. The base fee rate is 0.25% annually, reduced to 0.12% for the first $2.5 billion in assets for the first 12 months after listing. The trust is expected to continue issuing shares under controlled risk conditions.
Views and Analysis on Crypto ETFs
The ETF Store President: A 50% Drawdown is Not Uncommon for Bitcoin, ETF Investors are Still Bottom Fishing
Nate Geraci, president of The ETF Store, stated that a 50% drawdown is not uncommon for long-term Bitcoin investors and may not be the last time it occurs. He pointed out that despite the market experiencing significant declines, there are no obvious signs of panic among spot Bitcoin ETF investors, and fund flow data indicates that these investors remain steady.
Geraci believes that based on recent fund movements, some ETF investors are more inclined to accumulate during pullbacks.
Bloomberg Analyst: Bitcoin ETF Sees Large Inflows, Whether a Real Rebound Remains to be Seen
Bloomberg senior ETF analyst Eric Balchunas posted on platform X that yesterday, Bitcoin ETFs attracted about $500 million in inflows, the largest single-day increase in recent times, with a total inflow of about $750 million over the past two days, coinciding with a period of strong market pessimism. He described this inflow as "like hitting a home run during a slump," providing a boost to the market.
Year-to-date, Bitcoin ETFs have still seen a cumulative net outflow of less than $2 billion, but it remains unclear whether this marks the beginning of a real rebound or just a temporary "dead cat bounce."
Viewpoint: Bitcoin Prices Will Not Be Explicitly Suppressed by ETF-Authorized Institutions, but Price Discovery Mechanisms May Be Affected
Discussions regarding market manipulation speculations involving Jane Street and Bitcoin ETF mechanisms continue to evolve. Bitwise advisor Jeff Park stated that the question of whether Bitcoin prices are suppressed by Jane Street is not aimed at a single institution but is determined by the structural characteristics within the Bitcoin ETF framework.
Each authorized participant (AP), including Jane Street Capital, JPMorgan, Goldman Sachs, etc., has the exemption to create and redeem ETF shares, allowing them to flexibly manage positions in the market, including using futures or derivatives for hedging without having to purchase spot Bitcoin, which may affect the price discovery mechanism.
This gray area of operation stems from regulatory exemptions and SEC approvals for physical delivery. Although there is no evidence that any AP explicitly suppresses Bitcoin prices, the existing structure may alter the natural mechanisms of price formation, warranting attention from regulators and investors.
Bloomberg ETF analyst Eric Balchunas responded that this mechanism is indeed difficult to understand, and he is curious about who or what force is behind the "patterned sell-offs" that appear daily and then suddenly disappear. Samson Mow, CEO of Bitcoin technology company Jan3, stated that becoming an AP is not the only factor in suppressing prices; the key lies in how "extensive" their undisclosed trading and hedging activities are. This is a channel that brings capital costs close to zero.
Bitfinex: ETF Outflows and Large Holder Sell-offs Pressure Bitcoin, $53,000 May Be a Key Support
According to the Bitfinex Alpha report, due to weak inflows into Bitcoin spot ETFs and ongoing sell-offs by large holders, the Bitcoin market remains in a high time frame downtrend.
The report noted that although Bitcoin has rebounded 20% since its low on February 5, it has not yet confirmed a bottom. Year-to-date, US Bitcoin spot ETFs have seen a cumulative net outflow of $2.6 billion, with institutional investors' "ETF fatigue" exacerbating the selling pressure. On-chain data shows that approximately 64% of the inflow funds to exchanges currently come from large holders (whales), the highest percentage since October 2015.
Additionally, influenced by US tariff policies and macro uncertainties, options traders are again paying premiums for downside risks, with market sentiment leaning cautious. Currently, the realized price of $53,000 is viewed as a key support level for the mid-term market.
Bloomberg Analyst: Institutions Reduced Holdings in Bitcoin ETFs in Q4, Advisors and Hedge Funds are the Largest Sellers
Bloomberg analyst James Seyffart posted on platform X that institutional investors submitting 13F reports to the US Securities and Exchange Commission reduced their holdings in Bitcoin ETF positions overall in Q4 2025, with investment advisory firms and hedge funds being the two largest categories of institutions by position size, becoming the main sellers in the market.
Overall, institutions submitting 13F reports sold ETF shares equivalent to approximately 25,000 Bitcoins in Q4 2025.
Bloomberg: Hedge Funds That Once Fueled the US Bitcoin ETF Boom are Rapidly Exiting, Q4 2025 Bitcoin ETF Holdings Decreased by 28%
According to Bloomberg, hedge funds that once fueled the US Bitcoin ETF boom are rapidly exiting.
Data compiled by CF Benchmarks, a wholly-owned subsidiary of the crypto trading platform Kraken, shows that the total allocation of Bitcoin ETFs held by the largest hedge funds has decreased by 28%. Gabe Selby, head of research at CF Benchmarks, wrote in a research report on February 19: "The dominant theme over the past two quarters has been hedge funds' de-risking operations. The spike and subsequent drop in October seem to have triggered systematic liquidation." Brevan Howard significantly adjusted its holdings in BlackRock's iShares Bitcoin Trust, becoming the largest seller of this spot ETF in Q4. Its holdings decreased by approximately 86% to 5.5 million shares, reducing the value of its spot position from about $2.4 billion to $275 million. Bitcoin prices have fallen alongside macro risks, and at certain stages, the declines were even greater, undermining the logic previously presented to institutional investors—that Bitcoin could hedge against inflation, currency devaluation, or stock market pressures.

Mixin has launched USTD-margined perpetual contracts, bringing derivative trading into the chat scene.
The privacy-focused crypto wallet Mixin announced today the launch of its U-based perpetual contract (a derivative priced in USDT). Unlike traditional exchanges, Mixin has taken a new approach by "liberating" derivative trading from isolated matching engines and embedding it into the instant messaging environment.
Users can directly open positions within the app with leverage of up to 200x, while sharing positions, discussing strategies, and copy trading within private communities. Trading, social interaction, and asset management are integrated into the same interface.
Based on its non-custodial architecture, Mixin has eliminated friction from the traditional onboarding process, allowing users to participate in perpetual contract trading without identity verification.
The trading process has been streamlined into five steps:
· Choose the trading asset
· Select long or short
· Input position size and leverage
· Confirm order details
· Confirm and open the position
The interface provides real-time visualization of price, position, and profit and loss (PnL), allowing users to complete trades without switching between multiple modules.
Mixin has directly integrated social features into the derivative trading environment. Users can create private trading communities and interact around real-time positions:
· End-to-end encrypted private groups supporting up to 1024 members
· End-to-end encrypted voice communication
· One-click position sharing
· One-click trade copying
On the execution side, Mixin aggregates liquidity from multiple sources and accesses decentralized protocol and external market liquidity through a unified trading interface.
By combining social interaction with trade execution, Mixin enables users to collaborate, share, and execute trading strategies instantly within the same environment.
Mixin has also introduced a referral incentive system based on trading behavior:
· Users can join with an invite code
· Up to 60% of trading fees as referral rewards
· Incentive mechanism designed for long-term, sustainable earnings
This model aims to drive user-driven network expansion and organic growth.
Mixin's derivative transactions are built on top of its existing self-custody wallet infrastructure, with core features including:
· Separation of transaction account and asset storage
· User full control over assets
· Platform does not custody user funds
· Built-in privacy mechanisms to reduce data exposure
The system aims to strike a balance between transaction efficiency, asset security, and privacy protection.
Against the background of perpetual contracts becoming a mainstream trading tool, Mixin is exploring a different development direction by lowering barriers, enhancing social and privacy attributes.
The platform does not only view transactions as execution actions but positions them as a networked activity: transactions have social attributes, strategies can be shared, and relationships between individuals also become part of the financial system.
Mixin's design is based on a user-initiated, user-controlled model. The platform neither custodies assets nor executes transactions on behalf of users.
This model aligns with a statement issued by the U.S. Securities and Exchange Commission (SEC) on April 13, 2026, titled "Staff Statement on Whether Partial User Interface Used in Preparing Cryptocurrency Securities Transactions May Require Broker-Dealer Registration."
The statement indicates that, under the premise where transactions are entirely initiated and controlled by users, non-custodial service providers that offer neutral interfaces may not need to register as broker-dealers or exchanges.
Mixin is a decentralized, self-custodial privacy wallet designed to provide secure and efficient digital asset management services.
Its core capabilities include:
· Aggregation: integrating multi-chain assets and routing between different transaction paths to simplify user operations
· High liquidity access: connecting to various liquidity sources, including decentralized protocols and external markets
· Decentralization: achieving full user control over assets without relying on custodial intermediaries
· Privacy protection: safeguarding assets and data through MPC, CryptoNote, and end-to-end encrypted communication
Mixin has been in operation for over 8 years, supporting over 40 blockchains and more than 10,000 assets, with a global user base exceeding 10 million and an on-chain self-custodied asset scale of over $1 billion.
