Around May 1, 2026, the crypto ETF market experienced two news items with drastically different scales and directions within a short time. On one side was BlackRock's substantial movement of related products on-chain: according to on-chain data, about three hours before this report, BlackRock deposited 26,273 ETH into Coinbase Prime via its Ethereum spot ETF—ETHA, valued at approximately $59.89 million at the time; simultaneously, it deposited 226.677 BTC via its Bitcoin spot ETF—IBIT, amounting to about $17.54 million. The nominal value of these two transfers totaled over $77 million, with the recipient being addresses related to Coinbase Prime. Whether in terms of fund volume or the status of the products involved, this was enough to create a strong signal in the on-chain monitoring and ETF observer community. It is important to emphasize that public information did not clarify the relationship between these two transfers and actions such as subscription, redemption, or market-making adjustments, and their purpose remains undisclosed.

Almost simultaneously, on the other end, Bitwise announced its decision to close and liquidate two crypto-related ETFs: BTOP (Trend Rotation Strategy ETF) and BWEB (Web3 Theme ETF). The timeline provided in the announcement was quite clear: May 21, 2026, was set as the last trading day for both products, after which trading in the secondary market would cease; May 29, 2026, would be the liquidation date, at which point shares not sold before the last trading day would automatically convert to cash redemption based on the net asset value (NAV) on that day. Bitwise did not disclose the specific reasons for closing these two funds in the announcement. When looking at both events together, on one side there was BlackRock's sustained on-chain activity involving tens of millions of dollars in its leading spot products, while on the other, non-core strategy and theme products were opting to exit, forming a temporal correlation and further reinforcing an already apparent pattern: the crypto ETF market is continuing to grow with leading spot products like IBIT and ETHA, while tail-end strategy and thematic products are facing pressures of clearing and contraction.

BlackRock transfers over $77 million to Coinbase

Shortly before Bitwise announced the liquidation, BlackRock's two spot products again showed significant on-chain activity: depositing 26,273 ETH into Coinbase Prime via the Ethereum spot ETF ETHA, valued at approximately $59.89 million at the time; simultaneously, depositing 226.677 BTC into the same custodian via the Bitcoin spot ETF IBIT, with a nominal value of about $17.54 million (both according to a single source). The combined scale of these two transactions exceeded $77 million, with the recipient being addresses related to Coinbase Prime, representing a typical large-scale institutional custody and trading path. This transfer occurred about three hours before the report, but the specific block timestamp has not been disclosed, and on-chain confirmation is limited to asset scale, currency types, and direction.

From an operational mechanism perspective, during the share subscription and redemption process of a spot crypto ETF, authorized participants typically transfer or withdraw underlying assets to/from the custodian. Accordingly, large transfers in and out will be recorded on-chain, which is a routine part of product operation and an inevitable technical process when maintaining share and asset matching for leading spot products like IBIT and ETHA. However, regarding the two concentrated transfers to Coinbase Prime, public information has not clarified their specific correspondence with subscriptions, redemptions, market-making adjustments, or any other internal arrangements, making it impossible to infer a clearer funding intention from a single transfer event at this stage. Notably, reports mentioned that on April 30, 2026, there were also transfers related to BlackRock's ETF of about 16,609 ETH and 725.36 BTC to Coinbase Prime, but this data still needs further verification and cannot yet serve as a confirming sample. If we combine these limited and partially unverified records, it only indicates that currently, the frequency of on-chain asset migrations by BlackRock around spot products like IBIT and ETHA is sufficient to form a visible rhythm, but the nature of each specific transfer requires further disclosures or more data for clarification.

Bitwise delists two crypto ETFs: How investors can exit

As an asset management institution focused on crypto assets, Bitwise had previously launched multiple ETFs around crypto assets, including the trend rotation strategy product BTOP and the Web3 theme product BWEB. According to the latest announcement, Bitwise plans to close and liquidate these two ETFs, meaning that these non-pure spot, relatively complex strategy and thematic products will be completely exiting the public market. The announcement did not comment on the past performance or funding status of the products, only clearly outlined the delisting steps and arrangements for the coming weeks from a procedural perspective.

According to the timeline, the last trading day for BTOP and BWEB is set for May 21, 2026. Before that date, the secondary market can still facilitate normal trades, and if investors want to choose their exit price, they can sell their holdings through brokers in the market; once this deadline passes, the two ETFs will cease normal trading on the exchange, essentially closing the liquidity channel. Following this, Bitwise plans to conduct formal liquidation of the two funds on May 29, 2026, at which point all remaining shares not sold in advance will be converted into cash based on the net asset value (NAV) of the fund on that day, distributed by the fund manager to the holders (according to a single source).

The announcement particularly reminds investors to focus on the two key dates mentioned above and to make choices between "selling early in the market" and "holding until May 29 for automatic cash redemption based on NAV" according to their liquidity needs and risk preferences. It is crucial to emphasize that Bitwise did not disclose the specific reasons for closing BTOP and BWEB in the announcement, only stating the delisting path and arrangements for investor rights from a procedural standpoint; in the absence of public information, the outside world similarly cannot directly attribute this closure to performance, fund flows, or regulatory environment as any single factor. At this stage, what investors can do is to understand the liquidation mechanism under the established timeline, manage their holdings rather than extending judgments based on unverified speculation.

Funds concentrate towards giants, thematic ETFs face elimination rounds

In the larger market structure, the simultaneous announcement of BlackRock and Bitwise's actions—one increasing exposure while the other exits—reflects a typical cross-section of the crypto ETF gradually moving towards "larger head products, clearing tail-end products". On one hand, about three hours before the May 1, 2026 report, BlackRock planned to deposit over $77 million in nominal value of Bitcoin and Ethereum assets via IBIT and ETHA into Coinbase Prime; these on-chain migrations rely on the rapidly growing leading spot products since 2024, occupying a core position in fund discussions and trading attention. On the other hand, Bitwise announced the closure of the BTOP and BWEB strategy and Web3 thematic ETFs, choosing to cease trading on May 21, 2026, and complete liquidation on May 29, 2026, which means that some "long tail" products are starting to exit the stage.

Research briefs indicate that the recent overall inflow of funds into crypto ETFs has shown significant volatility; under this backdrop, the structural differentiation of the products has been further amplified: Bitcoin and Ethereum spot ETFs represented by IBIT and ETHA firmly occupy the "main track", while non-core products like strategy-type and thematic-type ETFs generally face disadvantages in scale and liquidity, making them more vulnerable in fee competition. The BTOP and BWEB mentioned by Bitwise are precisely examples of this relatively complex product structure that do not revolve around a single large-cap asset; their exit is less an isolated incident for specific companies and more a sample of the entire industry undergoing "product selection" under funding preferences and cost constraints.

It is important to emphasize that Bitwise's closure of BTOP and BWEB cannot be oversimplified to "due to a single variable"—whether performance, fund flows, or regulatory environment, in the absence of public information, cannot be determined as the sole driving factor. Likewise, the specific use of BlackRock’s recent large transfers has not been disclosed, and the outside world cannot force a causal link between the two. A more cautious interpretation is to consider these two groups of neighboring events as different aspects of the same stage of industry differentiation: leading spot ETFs continue to absorb incremental funds through scale advantages and trading depth, while some strategy and thematic products that struggle to form competitive liquidity and fee structures are forced into an "elimination round" rhythm. For investors, it is more critical to reassess the structural position and liquidity conditions of the crypto ETFs they hold based on this, rather than seeking excessively clear storylines for isolated cases.

From on-chain transfers to ETF shares: How funds flow within the system

If we narrow the perspective from "which fund is expanding or exiting" to a single transaction, BlackRock's related address transferred 26,273 ETH and 226.677 BTC (with a total nominal scale exceeding $77 million) to Coinbase Prime about three hours before the report, indicating just one thing: this portion of assets was migrated from one custody/control domain to another. According to public information, external observers cannot determine whether this corresponds to primary market subscriptions or redemptions of the ETF, or to market maker adjustments, internal account restructuring, etc., making it impossible to draw direct conclusions about "buying" or "selling".

In the standard mechanism of a spot crypto ETF, the flow of funds in the primary market revolves around "authorized participants (AP) - fund managers - custodians":
● When ETF shares are subscribed, the AP delivers underlying assets (like BTC or ETH) to the fund system, which typically enters the account through custodians and trading platforms like Coinbase Prime; once the custodian confirms receipt of the corresponding amount of coins, the fund manager issues new ETF shares to the AP.
● When ETF shares are redeemed, the process reverses: the AP returns the ETF shares, the fund manager cancels them, and the custodian then transfers the corresponding amounts of BTC or ETH back to the AP or its designated account.
Both types of transactions will leave large records of transfers in and out on-chain, but behind a single on-chain transfer, it could be a single large subscription/redemption or the net aggregation of multiple subscriptions/redemptions, and the on-chain transactions themselves do not annotate these details.

Furthermore, actions on the market-making and custodial levels will overlap with the subscription and redemption logic. Market makers, in order to maintain the proximity of secondary market prices to net asset value (NAV), will adjust positions along two dimensions: on one hand through buying and selling ETF shares in the market, and on the other hand initiating subscriptions/redemptions in the primary market, or trading spot and derivatives off-exchange with the custodian; custodians may also transfer assets between different wallets or product sub-pools for risk management or operational needs. All of these could manifest as large on-chain transfers, but the corresponding changes in ETF shares are often disclosed with different frequencies and standards, leading to temporal misalignment. In the case of BlackRock's transfer of ETH and BTC to Coinbase Prime, the existing public information can only confirm that assets flow to the custodian address; regarding the precise correspondence between this and the scale of ETF subscriptions/redemptions, market maker positions, or subsequent secondary market transactions, external data currently cannot provide a single, definitive reading, which is a cognitive boundary that needs to be established first when interpreting such on-chain signals.

Fast-tracked differentiation in crypto ETF holdings and selection methodology

In the context of incomplete disclosures from both on-chain signals and announcement information, one relatively clear point is presented: on one end, BlackRock continues to transfer significant assets on-chain with core products like IBIT and ETHA, with this latest deposit of over $77 million in BTC and ETH into Coinbase Prime reinforcing its position on the side of crypto ETFs; on the other end, Bitwise announced the closure of BTOP and BWEB, providing clear schedules for the last trading day and liquidation date. These two types of actions collectively outline an accelerating differentiated structure—with leading institutions and leading spot products reinforcing their presence while strategy-type and thematic-type non-core ETFs exit in an orderly manner based on established mechanisms.

For investors who already hold BTOP or BWEB, the primary task now is not to interpret market sentiment but to manage liquidity according to the timeline: the last trading day for the two funds is May 21, 2026, before which investors can proactively sell in the secondary market, adjusting prices and cash positions; May 29, 2026, is the liquidation date, at which point shares not sold in advance will automatically be redeemed as cash based on the net asset value (NAV) at that time. Whether to choose to sell early or wait for automatic redemption should take into account the potential large funding needs that may arise before and after late May, avoiding passive risk due to timing mismatches in capital return.

For longer-term holdings and fund selection, the methodology should lean towards quantifiable data dimensions, rather than merely considering short-term topic trends or singular events: firstly, assets under management (AUM), as larger products typically have advantages in efficiency of subscriptions and redemptions as well as operational stability; secondly, average daily trading volume and bid-ask spreads in the secondary market, directly determining slippage costs and execution difficulties for entry and exit; thirdly, management fee rates, as persistent fee differences can significantly erode returns on highly volatile assets; fourthly, product positioning and structural complexity, as the closure of BTOP and BWEB indicates the real possibility of termination for strategy-type and thematic-type products, necessitating prior evaluation of whether their strategies can maintain scale support. Importantly, in the absence of official explanations, do not forcibly attribute a single transfer or the closure of a specific product to any factors; instead, continuously monitor announcements, evaluate existing risks based on disclosed terms, treating the decision to hold or exit as part of a repeatable risk management and asset allocation strategy.
