Strategy’s era as the dominant Bitcoin buyer may have come to an end following last week’s STRC turmoil, which cast doubt on the company’s Bitcoin-buying strategy and sent the cryptocurrency to a nearly two-year low, according to Bitwise chief investment officer Matt Hougan.

“For years, Strategy has been the most dominant Bitcoin buyer in the world and a one-way source of Bitcoin demand. Those days are likely over,” Hougan said Thursday. 

“I just expect it to be a less important figure in Bitcoin in the next cycle than it was in the last,” Hougan said, adding that investment banks, asset managers, pensions, endowments and sovereign wealth funds will likely replace Strategy as Bitcoin’s primary demand driver.

Confidence in Strategy’s Bitcoin-buying model weakened late last month when its main perpetual preferred stock offering — Stretch (STRC) — broke sharply from its $100 par value to below $75, raising fears that its dividend model was unsustainable. 

The STRC incident coincided with Bitcoin (BTC) falling to a 21-month low of $58,190 on June 25, further rattling confidence across the crypto market. 

Strategy responded by committing to sell Bitcoin where necessary to fund dividends and by expanding its US dollar reserve to $2.55 billion — easing immediate concerns but weakening its position as the industry’s most aggressive Bitcoin buyer, Hougan said.

Hougan said he still expects Strategy to be a “net buyer” in the next bull run, however.

STRC example of “financial engineering” gone wrong

Hougan described the STRC incident as “classic end-of-cycle dynamics” and likened its collapse to a similar case of “financial engineering” in 2021, when Grayscale’s GBTC premium imploded.

“Money searching for high yields and low volatility was used to buy Bitcoin, which offers neither,” Hougan said. “This money never really fit Bitcoin. And so, it needs to be cleared out before we can find a bottom. That’s what’s happening today.”

Strategy’s issue with STRC overblown: Strive CEO

Strive CEO Matt Cole, however, said Strategy’s incident with STRC has drawn too much media attention and pushed down Bitcoin’s price more than it should have.

Speaking with NovaDius Wealth Management president Nate Geraci on Thursday, Cole noted that Strategy’s 847,363 Bitcoin represents just 4% of the total supply, and while Bitcoin isn’t a public company, by the US Securities and Exchange Commission’s standards, a 4% stake wouldn’t be considered material. 

“If one person owned 4%, you don’t even have to report that publicly to the SEC because the SEC deems 4% to be immaterial. They start to view a position to be material at 5%.”

Strategy isn’t facing liquidity risk: Hougan

Despite concern over STRC, Hougan said Strategy has $52 billion worth of liquid assets marked against $7 billion of debt, and that Bitcoin would need to drop another 70% (about $18,500) for the company to be put at risk.

Hougan also noted that if Strategy were to start selling its Bitcoin today, it could cover dividends from STRC and its other perpetual preferred stock offerings for the next 28 years.

Magazine: Bitcoin decouples from tech stocks, Ether eyes ‘selling wave’: Market Moves

Tokenization platform Securitize rallied on its New York Stock Exchange debut on Thursday, as it brought tokenized versions of its shares to two blockchains.

The company, which is backed by BlackRock and Morgan Stanley, began trading on the NYSE under the ticker SECZ on Thursday after merging with a Cantor Fitzgerald-backed special-purpose acquisition company to take it public.

Securitize said Thursday that it simultaneously launched tokenized versions of its shares on the Avalanche and Solana blockchains, which will be available to eligible US investors on its platform.

It marks the first time a newly public company has also offered tokenized stocks, an area of crypto technology that has quickly gained attention among major institutions drawn to the idea that it can bring deeper liquidity and longer trading hours.

Securitize has carved out a lead in the tokenization space for institutions. It partnered with the NYSE in March to create tokenized assets for the exchange’s upcoming tokenized securities platform.

US laws allow for tokenized stocks, Securitize says

Securitize said that tokenizing its stock demonstrates that tokenized securities “can be issued and accessed in the US under existing securities laws and market structure,” adding that access will be subject to onboarding, eligibility, and customer ID and money-laundering checks.

“We have long said that public equities are moving on-chain, and there is no stronger validation of that belief than tokenizing our own public stock on Day 1,” said Securitize co-founder and CEO Carlos Domingo.

“SECZ is not a synthetic token or offshore wrapper. It is issuer-sponsored tokenization of the same common stock trading on the NYSE, made available through regulated infrastructure,” he added. “This is how tokenization should scale: with real ownership, regulatory clarity and the issuer at the center.”

The US Securities and Exchange Commission clarified in January that issuer-sponsored tokenized securities are still subject to US securities laws.

In mid-May, the SEC was reportedly ready to announce an exemption for the trading of tokenized stocks, but delayed the plan later that month after stock exchange officials raised concerns over how it would be implemented.

Securitize shares rise on debut

Shares in Securitize (SECZ) hit a high of $13.70 in trading Thursday but retracted slightly and ended the day at $12.30, a gain of 4.4%. The share price continued to climb 2.4% after-hours to $12.60.

Securitize raised $400 million from its public offering at a valuation of more than $1 billion.

The market for tokenized real-world assets currently exceeds $43 billion, the majority of which is tokenized money market funds, while tokenized commodities account for nearly $7 billion and tokenized stocks account for $1.6 billion, according to Token Terminal.

Analysts expect the tokenization market to grow quickly in the coming years, with Citigroup predicting last month that it could grow to between $5.5 trillion and $8.2 trillion by 2030.

Big Questions: Do we really only need 2–5 cryptocurrencies?

Bitcoin was sold as digital gold, an uncorrelated hedge that would hold up when markets broke. In 2026 it fell roughly 50% alongside the Nasdaq while gold hit record highs. So what is Bitcoin now, and did the hedge thesis ever survive contact with Wall Street?

Bitcoin was supposed to be the asset that zigged when everything else zagged. For years it was sold as digital gold, an uncorrelated hedge that would protect a portfolio when stocks fell and uncertainty rose. In 2026, it has done close to the opposite. Bitcoin is down roughly 50% from its October 2025 record near $126,200, and it fell in near lockstep with technology stocks while gold climbed to record highs above $5,000 an ounce.

The asset marketed as a crisis hedge behaved like a leveraged bet on the same risk appetite that drives the Nasdaq. This piece works through the evidence that Bitcoin now trades like a tech stock, why that happened, and the serious counter-argument that the story is more complicated than a simple correlation chart suggests. The answer matters because it changes how investors should size Bitcoin, how they should compare it with gold, and whether the ETF era strengthened the asset or quietly rewired it into the same macro trade it was supposed to diversify away from.

The evidence: Bitcoin moves with the Nasdaq now

The correlation data is the starting point, and it is stark. Rolling 30-day correlations between Bitcoin and the Nasdaq 100 reached about 0.80 early in 2026, the highest level in close to four years, and Bitcoin’s longer-run five-year correlation with the tech-heavy index sits near 0.54. Standard Chartered analysts have pegged the Bitcoin-Nasdaq correlation around 0.5 with peaks near 0.8, while short-term readings against U.S. tech indices have ranged between roughly 0.55 and 0.68 through the year. However you measure it, Bitcoin and the Nasdaq have been moving together.

The relationship with gold has gone the other way. As Bitcoin’s tie to tech strengthened, its correlation with gold fell toward zero, at points reaching just 0.2. And the price paths made the divergence impossible to ignore. While Bitcoin dropped through 2026, gold surged to record highs above $5,000 and briefly toward $5,600 an ounce, outperforming Bitcoin by a wide margin over the same stretch.

The clearest test came under real stress. When conflict in the Middle East pushed oil higher and rattled markets, gold did what a safe haven does and climbed, while Bitcoin fell alongside risk assets. A hedge is supposed to prove itself precisely in those moments, and Bitcoin did not. The pattern that defined 2026 is simple to state: when the tech trade got hit, Bitcoin got hit, and when investors fled to safety, they chose gold.

Why the digital gold thesis mattered

To understand what has been lost, it helps to recall what the digital gold pitch actually claimed. Bitcoin’s founding appeal to institutions was not only its potential for gains but its supposed independence from everything else. It had a fixed supply capped at 21 million coins, no central issuer, and no cash flows tied to the economy, which in theory made it a store of value that would not move with stocks, bonds, or the business cycle. In its early years, Bitcoin was not just uncorrelated with equities; it was uncorrelated with nearly every major asset class, which made it look like the ultimate portfolio diversifier.

That property was the entire institutional case. A diversifier that zigs when the rest of a portfolio zags reduces overall risk, and that is worth paying for. Wall Street bought into the idea that Bitcoin could serve as a hedge against monetary debasement, market volatility, and economic uncertainty, a role gold has played for centuries. The digital gold narrative underpinned much of the adoption story, from corporate treasuries to the campaign for spot ETFs, because it promised something distinct from a simple speculative growth bet.

The trouble is that an asset’s identity depends not only on its design but on who owns it and how it is traded. Bitcoin’s code did not change in 2026. What changed is the profile of the people holding it and the machinery through which they buy and sell. That shift, more than anything about the protocol, is what turned the hedge into a high-beta risk asset.

What changed: the ETF made Bitcoin a portfolio asset

The pivotal event was the arrival of spot Bitcoin ETFs in January 2024, and the irony is sharp. The ETFs were celebrated as the moment Bitcoin was legitimized, folded into the regulated financial system at last. That same integration is what tied it to the equity market. Research published in late 2025 found robust evidence that ETF approval structurally altered Bitcoin’s role, marking a shift from an independent, idiosyncratic asset toward a conventional risk asset whose correlation with the S&P 500 rose sharply after the launch.

The mechanism is straightforward once you follow the money. Before ETFs, much of Bitcoin sat with crypto-native holders who traded it on its own logic. After ETFs, large institutions could hold Bitcoin exposure inside the same portfolios as their technology stocks, managed by the same risk desks using the same tools. When those desks adjust risk, they buy or sell Bitcoin and tech at the same time, for the same reasons, which welds the two together.

The marginal dollar in Bitcoin became, increasingly, the same dollar chasing artificial intelligence and growth equities, so when that dollar turned cautious, it sold both at once. This is the deeper story behind capital rotating into AI stocks that has drained crypto momentum all year. It is not only that money left Bitcoin for semiconductors; it is that the money still in Bitcoin now behaves like the money in tech, responding to the same Federal Reserve signals, the same liquidity conditions, and the same growth expectations. Bitcoin did not choose to become a tech stock. Its new owners made it one.

Cross-margining lets your whole account balance backstop every open trade, so a winning position can keep a losing one alive. It is more capital-efficient than isolated margin, and it can also wipe out your entire account in one bad move. Here is how it works.

Cross-margining is a way of managing collateral in leveraged trading where your entire account balance backs all of your open positions at once, instead of each trade standing on its own. In practice, that means the profit or spare equity in one position can be used to support another that is losing, which can keep trades alive through volatility. The trade-off is that your whole account is exposed: a large enough loss draws on the entire balance and can liquidate everything. Cross margin is one of the two main margin modes offered on crypto trading platforms, the other being isolated margin, and understanding the difference is essential to managing risk. This explainer covers how margin trading works, how cross and isolated margin differ, a worked example, the pros and cons, and how the same idea operates at the institutional level.

Margin trading basics: leverage, collateral, liquidation

Cross-margining only makes sense once the basics of margin trading are clear. Margin trading means borrowing funds to open a position larger than your own cash balance would allow. The money you put up is the margin, and it serves as collateral for the borrowed funds. Leverage describes how much larger your position is than your own capital: at five-to-one leverage, a trader controls a position five times the size of their margin. Leverage amplifies everything, so both gains and losses grow in proportion to the position size instead of the smaller amount of capital actually committed.

Two thresholds govern a margin position. The initial margin is the collateral required to open the position. The maintenance margin is the minimum equity that must be kept to hold it open. As long as the position’s equity stays above the maintenance margin, the trade continues. If the market moves against the position enough that equity falls below the maintenance margin, the platform issues a margin call or, more commonly in crypto, moves straight to liquidation.

Liquidation is the forced closure of a position when its equity drops below the maintenance requirement. The platform’s liquidation engine closes the position at market prices, sometimes in partial steps, to prevent the account from going negative. Because leverage magnifies losses, liquidation can happen fast: at high leverage, a small adverse price move can wipe out the margin buffer entirely. This is the central risk of all margin trading, and the choice between cross and isolated margin is fundamentally a choice about how liquidation is calculated and how much of your account is exposed to it.

Cross margin versus isolated margin: the core difference

The two margin modes differ in one crucial respect: what pool of collateral backs each position. In cross margin, all the funds in your account form a single shared pool that backs every open position together. Unrealized profits and spare equity from one position can flow to support another that is drawing down, which can delay or prevent the liquidation of the losing trade. The account is managed as one book, and liquidation becomes a portfolio-level event that depends on the combined equity of everything you hold.

In isolated margin, collateral is ring-fenced to each position individually. You decide how much of your funds to assign to a specific trade, and that amount is the maximum you can lose on it. If the position is liquidated, only its allocated collateral is lost, and the rest of your account, including your other positions, is untouched. Isolated margin gives you a predictable, per-trade liquidation price and a hard cap on the damage any single idea can do, at the cost of not being able to draw on the rest of your balance to save a position.

The consequence is a clear trade-off between capital efficiency and risk containment. Cross margin uses your capital more efficiently, because idle equity and winning positions automatically backstop losing ones, and it tends to produce fewer forced liquidations on individual legs. But it places your entire account on the line, since a bad enough move can consume the whole balance. Isolated margin sacrifices efficiency for control: each position is walled off, so a single blow-up cannot spread, but you must actively manage collateral and accept more frequent single-position liquidations. Neither is inherently better; the right mode depends on the strategy.

A worked example

A concrete example makes the difference tangible. Imagine a trader with a $15,000 account who wants to open a leveraged long position on Bitcoin with an initial margin requirement of $5,000. Under cross margin, the entire $15,000 backs the position, giving a $10,000 buffer above the initial requirement. That large cushion makes liquidation far less likely on a normal pullback, because the whole account absorbs the drawdown. If the trader also holds other positions, profits on those can further support the Bitcoin trade. The catch is that if the combined account equity falls below the maintenance level, the liquidation engine can close positions and consume the full $15,000, not just a slice of it.

Now run the same trade under isolated margin. The trader allocates exactly $5,000 to the Bitcoin position and no more. If Bitcoin falls and the position is liquidated, the maximum loss is that $5,000, and the remaining $10,000 in the account is safe, available for other trades or simply preserved. The liquidation price is predictable and tied only to that position’s collateral. The downside is that the position has a much thinner buffer, so it will be liquidated sooner than the cross-margined version, since it cannot draw on the rest of the account to survive a dip.

The example shows the core tension. Cross margin gave the Bitcoin trade a bigger cushion and a better chance of surviving volatility, but it risked the entire $15,000. Isolated margin capped the loss at $5,000 but liquidated the position more readily. A trader who is confident and wants staying power, and who is comfortable risking the whole account, leans cross. A trader who wants a firm loss limit on a specific, uncertain bet leans isolated. The same $15,000 produces very different risk profiles depending on the mode chosen.

The pros and cons of cross-margining

Cross-margining has real advantages that explain its popularity among active and professional traders. Its main strength is capital efficiency: because all equity backs all positions, none of your capital sits idle behind a single trade, and winning positions automatically support losing ones. This produces a smoother equity curve and fewer forced exits on individual legs, which is especially valuable for hedged or offsetting strategies where one position is meant to counterbalance another. It is also simpler to monitor in one sense, since you watch a single account-level margin level instead of tracking collateral on many separate positions.

The disadvantages are equally real and more dangerous if ignored. The defining risk is that your entire account is exposed: once combined equity falls below the maintenance margin, liquidation can consume the whole balance, not a contained portion. This becomes acute when positions are correlated, which is common in crypto, where many assets move together. In a sharp, broad sell-off, several cross-margined positions can lose at once, draining account equity rapidly and triggering a cascade of liquidations across the book. A single violent move can therefore wipe out everything, where isolated margin would have contained the damage.

Cross margin also carries a psychological hazard. Because the shared pool makes positions feel more resilient, it can tempt traders to over-leverage, opening larger positions than they should because the buffer looks generous. That temptation, combined with the whole-account exposure, is how traders turn a manageable loss into a total one. The mode rewards discipline and punishes its absence. Used carefully within a hedged framework, cross margin is efficient and forgiving of ordinary volatility; used carelessly with correlated, over-leveraged bets, it is the fastest route to a blown-up account.

When to use cross versus isolated

The choice between the modes should follow the strategy rather than habit. Cross margin fits situations where positions offset or support one another. Hedging programs, basis trades, pairs trades, and market-making all benefit from a shared collateral pool, because a gain on one leg naturally cushions a loss on another, and pooling the collateral reduces the chance of an unnecessary single-leg liquidation. Core positions that a trader intends to hold through volatility also suit cross margin, since the deeper buffer provides staying power. In these cases, the whole-account exposure is an acceptable trade for the efficiency and resilience gained.

Isolated margin fits the opposite situations. Speculative, event-driven, or high-volatility bets, and single-ticket trades where the outcome is uncertain, are better ring-fenced, so that if the idea fails it cannot damage the rest of the account. A trader taking a focused shot on a volatile small-cap token, for instance, can cap the loss at a fixed amount and sleep easily knowing the rest of the balance is safe. Isolated margin also suits newer traders building discipline, because it enforces a hard maximum loss per trade and makes the risk of each position explicit.

Many experienced traders combine both in a core-satellite structure. They run cross margin on a core book of hedged or offsetting positions that benefit from pooled equity, while keeping speculative satellite trades in isolated buckets with fixed loss caps. This keeps the core capital-efficient without letting a single high-risk bet sink the whole account. The practical rule is to match the mode to the intent of each trade: shared exposure for positions designed to work together, walled-off exposure for standalone bets you want to contain. Some platforms even offer a smart cross margin that nets opposite-direction positions across products, further improving efficiency for hedged books.

Cross-margining at the institutional level

The same principle that governs a retail trader’s account scales all the way up to the largest institutions, and it is worth seeing the connection. When a hedge fund or trading firm operates through a prime broker, the broker cross-margins the firm’s positions across entire asset classes, netting exposures in digital assets, foreign exchange, derivatives, and fixed income so the firm posts collateral against the combined risk of its whole book rather than each position separately. This is cross-margining as a foundation of professional trading, and it is a major reason institutions value prime brokers: it frees up enormous amounts of capital that would otherwise sit idle.

Crypto has begun importing this institutional version. Prime brokers serving digital assets now let clients cross-margin crypto positions against traditional exposures, and stablecoins have started to play the role of shared collateral in that system. Ripple’s RLUSD, for example, has been positioned as a stablecoin that enables cross-margining between digital assets and traditional markets through institutional prime brokerage, letting a firm post the token as collateral recognized across both worlds. That is the same idea a retail trader meets in a cross-margin account, applied at the scale of institutional portfolios spanning many markets.

Seeing the two levels together clarifies what cross-margining really is: a method for treating a collection of positions as a single risk pool to use capital more efficiently. For a retail trader, the pool is the account balance backing a handful of trades. For an institution, it is a multi-asset book backed by cash and collateral like stablecoins across a prime broker. The mechanics and the stakes differ by orders of magnitude, but the core logic, and the core trade-off between efficiency and concentrated risk is identical.

The risks you must respect

Whatever the level, cross-margining demands respect for a specific set of risks, and ignoring them is how accounts are lost. The first is correlation risk. Crypto assets frequently move together, so a broad sell-off can push multiple cross-margined positions into loss simultaneously, draining shared equity far faster than a single position would. The very diversification that looks like safety can become a synchronized drawdown when markets turn risk-off together, and the shared pool that was meant to cushion individual losses instead absorbs many at once.

The second is liquidation and leverage risk. Because cross margin can make positions feel durable, it invites higher leverage, and higher leverage means a smaller adverse move can breach the maintenance margin. When that happens in cross mode, the liquidation is a portfolio-level event that can close multiple positions and consume the whole account. Flash crashes and liquidation cascades, where forced selling drives prices lower and triggers still more liquidations, are especially dangerous, and thin order books during such events can cause execution at prices far worse than expected. The market has seen sharp, leverage-driven cascades wipe out over-extended traders in minutes.

The disciplined response is to size positions conservatively, avoid over-leverage, and match the margin mode to the trade. Use cross margin for genuinely hedged or core positions where offsetting exposure justifies the shared pool, and isolate speculative or high-beta bets so a single failure cannot spread. Set alerts and plan collateral top-ups in advance instead of reacting during a crash. Cross-margining is a powerful tool for capital efficiency, but it concentrates risk at the account level, and the traders who use it well are the ones who never forget that the whole balance is on the line.

The U.S. Treasury’s Office of Foreign Assets Control (OFAC) has expanded its sanctions targeting ISIS-Khorasan (ISIS-K), sanctioning 134 cryptocurrency wallet addresses tied to the group. ISIS-K has been designated as a Specially Designated Global Terrorist since September 2015.

OFAC added the addresses to its Specially Designated Nationals (SDN) list on Wednesday. The SDN designation covers individuals, entities, and digital asset addresses linked to terrorism and other illicit activity, bringing more crypto-linked points of contact into the U.S. enforcement framework. OFAC’s recent action outlines the update.

Key takeaways

• OFAC sanctioned 134 cryptocurrency wallet addresses associated with ISIS-Khorasan, adding them to the SDN list.
• Blockchain analysis by Chainalysis says 131 of the sanctioned addresses were on Tron and were frozen by Tether; three were on Monero.
• Chainalysis reports the Tron addresses received more than $1.4 million in crypto donations since 2023 and sent over $880,000.
• The new action follows OFAC’s prior ISIS-support financier sanctions issued on June 22.

OFAC adds 134 crypto addresses to the SDN list

The latest OFAC update is part of an ongoing effort to disrupt terrorist financing conducted through digital assets. By designating specific wallet addresses, OFAC places them within the SDN framework—aimed at preventing U.S. persons and covered businesses from dealing with the sanctioned parties or facilitating transactions tied to them.

According to OFAC’s description of the measure, earlier rounds focused on “key facilitators who enable ISIS to move funds among its regional affiliates.” The new tranche expands the net further by targeting additional wallet infrastructure associated with ISIS-K’s illicit financial activity. OFAC’s SDN list update records the addresses added this week.

Tether freezes Tron holdings; Chainalysis flags Monero addresses

Industry blockchain forensics firm Chainalysis, in a report released alongside the sanctions news, attributed the breakdown of wallets by network: 131 Tron addresses and three Monero addresses were identified in the OFAC action. Chainalysis said Tether froze balances tied to the 131 Tron addresses, while the remaining addresses were on the Monero network.

The freezing step matters operationally. Sanctions can create legal and compliance barriers, but the immediate restriction of balances by major stablecoin infrastructure can reduce the near-term ability of sanctioned actors to access funds—even before prosecutions or extended enforcement follow.

Chainalysis’ analysis of the specific wallets and their network exposure was published in its report on the July 2026 sanctions round: “ISIS Designation of Crypto Addresses — July 2026”.

Where the money flowed: donations and transfers traced on-chain

Chainalysis also described what it found when mapping the sanctioned wallets’ activity. The report says the 131 Tron addresses received more than $1.4 million in cryptocurrency donations since 2023 and sent over $880,000. The group has reportedly sought crypto donations historically through campaigns using websites and messaging platforms.

Beyond aggregate totals, Chainalysis says it identified donation-related addresses used across multiple networks—including Tron, Monero, and Bitcoin—and noted what it characterized as “significant exposure to mainstream services.” The firm also found wallets that routed funds to cryptocurrency exchanges based in Syria.

That mix—terror-linked wallets interacting with larger crypto services—highlights a key enforcement challenge. Even when an illicit actor uses anonymity-oriented networks (such as Monero), their broader financial graph can intersect with centralized or regulated endpoints through exchange flows, custody, or liquidity routes. For compliance teams, that intersection is often where disruptions become most practical.

Sanctions momentum builds after June 22 enforcement

This week’s OFAC action arrives a little more than a week after the agency sanctioned additional individuals and entities connected to ISIS-related financing. On June 22, OFAC sanctioned three individuals and six entities across Europe, the Middle East, and West Africa, including MSB Bitcoin Xchange (Syria) and MSB Spider (Turkey). OFAC’s June 22 press release describes that previous round and the agency’s rationale.

Comparing the two actions, the pattern appears to be widening from alleged facilitators toward the transactional endpoints used to receive or move funds. By adding wallet addresses to the SDN list, OFAC reduces flexibility for sanctioned networks and increases compliance pressure across exchanges, custodians, and stablecoin-related entities that manage address-based monitoring and balance controls.

It also reinforces the role of blockchain analytics in sanctions design. Chainalysis’ ability to identify donation flows and network-specific wallets helped connect the sanctions process to on-chain behavior, enabling a targeted approach rather than a broad, non-specific sweep.

Why blockchain intelligence is becoming central to enforcement

Across counter-terrorism and financial-crime policy, blockchain intelligence tools are moving from “supporting evidence” to operational components in enforcement. Earlier this year, TRM Labs said onchain evidence was key to securing convictions of three individuals for terrorism financing in Indonesia in 2024 and 2025. TRM Labs argued that courts have treated cryptocurrency evidence—such as wallet addresses, transaction histories, and on-chain flows—as admissible and capable of anchoring prosecution. The company described this in a statement on its site: TRM Labs: on-chain intelligence and terrorism financing prosecutions.

The broader implication for market participants is straightforward: sanctions enforcement increasingly depends on traceable, address-level data. That trend tends to raise the importance of robust address-screening and transaction monitoring, especially for companies that deal with stablecoin liquidity, exchange withdrawals, or custody services across multiple networks.

For readers following this area closely, the next question is how quickly more connected wallets and counterparties are identified—and whether additional enforcement actions will target exchange routes, intermediary services, or other infrastructure tied to the newly sanctioned addresses. Chainalysis’ reporting suggests ISIS-K’s crypto activity has been persistent, but OFAC’s approach is shifting toward more granular, address-specific disruption that can constrain access to funds in real time.

SBI Crypto, the cryptocurrency-focused unit of Japan’s SBI financial group, will shut down its Bitcoin mining pool after five years of operations. The company says it will end mining pool services on July 31 and will stop accepting mining shares at the same time, while asking miners to keep directing hashrate to the pool through the cutoff so final payouts can be calculated correctly.

Beyond the operational details, the closure underlines a shift in how SBI wants to position itself in crypto. Instead of concentrating on mining infrastructure, SBI has been expanding its broader strategy across exchanges and stablecoins—an approach that appears to be moving resources away from pool-based services.

Key takeaways

• SBI Crypto will stop accepting Bitcoin mining shares and close its mining pool on July 31.
• Miners are being told to maintain hashrate on SBI Crypto until the cutoff to ensure accurate final payouts.
• SimpleMining data places SBI Crypto’s pool among the largest globally—currently around the 12th position by hashrate.
• SBI Crypto has pointed customers toward alternative pools, including Braiins, Luxor, and NeoPool.
• The shutdown aligns with SBI’s wider push into trading and stablecoin-related initiatives rather than mining.

End of SBI Crypto’s Bitcoin pool service

In an announcement posted on its site, SBI Crypto confirmed it will terminate its mining pool operations on July 31 and end share submissions at the same time. The company did not cite a specific reason for closing the pool.

In the same update, SBI Crypto emphasized operational continuity for miners. It asked customers to keep submitting hashrate to the pool until the final day so the platform can complete its payout calculations based on end-of-period share data. “We would sincerely appreciate your continued support by mining with us until the final day of operation,” the company wrote.

Where SBI Crypto sits in global pool rankings

SBI Crypto launched its Bitcoin mining pool in March 2021, entering a competitive segment that, at the time, already included major pool operators such as Poolin, F2Pool, and Binance Pool.

According to data tracked by SimpleMining, SBI Crypto currently ranks as the 12th largest Bitcoin mining pool worldwide. The dataset attributes roughly 21.46 exahashes per second (EH/s) of hashrate to SBI Crypto, representing about 2.24% of the network’s total share.

That position is significantly behind the very top pools. SimpleMining data shows Foundry USA controls about 24.49% of total network share, while AntPool sits around 19.05%. Mid-tier and lower-tier pools such as ViaBTC and MARA Pool account for approximately 8.55% and 5.15% of global Bitcoin mining hashrate, respectively.

For miners and operators monitoring pool reliability, rankings like these matter because they can influence factors such as the consistency of payouts and the pool’s overall draw of hashpower. Even without SBI Crypto’s exact rationale, the size of its current share means the migration away from its pool is likely to be watched closely by miners looking to avoid disruptions around the end date.

Hashrate migration options SBI Crypto recommends

With the July 31 shutdown approaching, SBI Crypto encouraged miners to redirect their hashing power to other Bitcoin pool operators. In its announcement, the company named several alternatives, including Braiins, Luxor, and NeoPool.

SimpleMining’s ranking data suggests that Braiins and Luxor each account for roughly 2% to 3% of global Bitcoin hashrate—placing them in the mid-tier portion of the pool market. NeoPool, meanwhile, is not included among the top-ranked pools by hashrate in the SimpleMining dataset.

SBI Crypto also indicated that some operators may run special programs or offer preferential conditions for clients transitioning from its platform. It advised customers to contact each pool directly to understand any available terms.

That guidance is likely important for both large mining operators and smaller participants. When a pool shuts down, miners typically face a tradeoff between operational convenience and the economics of switching—such as how quickly a new pool can reflect incoming hashpower and what payout structures apply after migration.

The closure of SBI Crypto’s mining pool follows a broader pattern in SBI’s crypto strategy: shifting emphasis from mining toward expanding its financial-market role in digital assets.

Earlier, SBI Holdings agreed to acquire full control of the crypto exchange Bitbank in a deal valued at 46.7 billion Japanese yen (about $289 million), with the stated goal of building what it describes as Japan’s largest cryptocurrency exchange. SBI has also increased its focus on stablecoins—backing JPYSC, a new trust bank-backed Japanese yen stablecoin, and supporting Ripple’s rollout of its Ripple USD (RLUSD) stablecoin in Japan.

While the mining pool is closing due to SBI Crypto’s operational decision, these adjacent initiatives suggest where management believes growth is likely to be concentrated: in regulated exchange infrastructure and stablecoin rails rather than in running a corporate mining service.

For miners, the next question is less about long-term corporate strategy and more about execution: how smoothly hashrate transitions occur across pools and whether payout conditions remain stable around the July 31 cutoff. Watch SBI Crypto’s communications for any final operational clarifications, and track how major pools absorb redistributed hashpower as the shutdown date approaches.
