US stocks closed mixed on Thursday, with the Nasdaq falling 2.6% for its largest single-day decline since June 23, while the S&P 500 dropped 1.2%, its biggest drop since July 29. The Dow Jones Industrial Average edged up about 10 points. Renewed concerns over massive capital spending and financing risks at artificial intelligence companies drove a broad tech selloff, according to Sina Finance. Meta shares tumbled 8% despite the company third-quarter revenue exceeding market expectations and issuing optimistic guidance, as its hefty AI capital spending alarmed investors. AMD fell more than 8%, Micron Technology dropped 6%, and Nvidia declined 4%. Cloud computing provider CoreWeave plunged over 10% after its bond yields and credit default swap prices remained elevated, reflecting market concerns about its debt risks.
Nvidia CEO Jensen Huang said Thursday that demand for new cloud computing providers was "incredibly hot" but a shortage of capital was constraining industry growth. Wells Fargo traders noted in a report that Huang remarks on capital shortages unsettled the market, reigniting investor concerns about the credit market risk appetite.
Meanwhile, Meta indicated that its AI business still requires substantial capital investment, putting pressure on its shares and dragging the broader market. JPMorgan traders said Wednesday market optimism reversed in overnight trading, driven by Meta pre-market weakness and growing discussion about a potential renewed military strike against Iran after the US midterm elections. The firm also noted that investor confidence in AI financing prospects remains fragile following the recent tech correction. Separately, Middle East geopolitical risks escalated further.
Sources said the US and Israel plan to launch another military strike against Iran after the US midterm elections next month. US President Trump told reporters Wednesday evening that Washington is not currently negotiating with Tehran, adding "something will happen soon." Oil prices surged on the news. Brent crude futures rose 4% to close at $113.17 per barrel, while US WTI futures gained 2.39% to close at $99.47 per barrel. Safe-haven sentiment lifted US Treasury prices and pushed yields lower. The 10-year Treasury yield fell more than 18 basis points to 4.965%, its lowest in nearly a month, while the 2-year yield dropped over 17 basis points to 4.65%.

Paranoid developer Ignotus Nemo proposed a recursive aggregation approach for EIP-8288 on the Ethereum Research forum. According to Foresight News, the proposal recommends supporting multiple approved proof sizes so smaller aggregations can use smaller proofs.
Ignotus Nemo has implemented heterogeneous recursion in the Paranoid system, which runs both large and small state transition proofs on the public mainnet. The approach uses a finite library of authenticated verifier classes, with a separate accumulator channel for each class to handle cross-class deferred verification and ensure matrix claims remain valid during recursive steps.
The proposal also examines how to merge subclasses and manage dependencies when applying the mechanism to EIP-8288, as well as semantic compatibility between program identities and verifier classes.
Vitalik Buterin and Thomas Coratger proposed EIP-8288 in June 2026. The proposal addresses the large size of post-quantum signatures and STARK proofs, along with the high cost of verifying them onchain.

A contract account linked to address 0xfc667adba8d4837586078f4fdcdc29804337ca06 has recorded approximately $30.41 million in cumulative profit.

Polymarket has fired Chief Marketing Officer Matthew Modabber, who had held the position since January 2024. According to ChainCatcher, citing people familiar with the matter as reported by the New York Post, the dismissal followed an internal investigation into several incidents that drew public scrutiny and investor concern.
One issue involved allegations that Modabber's team created fake webpages to promote staged videos showing users making profits from fictitious trades. The Wall Street Journal reported on the matter in June, prompting an investigation by the U.S. Commodity Futures Trading Commission. The investigation is ongoing, and no violations have been established.
People familiar with the matter described Modabber as a close associate of 28-year-old CEO Shayne Coplan and said his impulsive decisions as an executive contributed to public relations crises. Polymarket is finalizing Modabber's departure agreement, with both sides maintaining mutual respect during the process.

The Glamsterdam hard fork on Ethereum’s Hoodi testnet has been delayed. According to ChainCatcher, smart contract security firm ChainSecurity said on October 22 that researchers found security-impacting issues in existing contracts and identified 13 real-world cases; they are conducting responsible disclosures with affected projects.
The announcement urged teams to review their contracts, while the Ethereum Foundation assesses the scope of the impact. It did not name the projects involved, provide contract addresses, or set a replacement fork date. The issues concern contracts that continue executing after catching failed external calls: under the gas changes reviewed, a failure handler could finish execution where it previously would have run out of gas and reverted. A caller could provide too little gas to complete the intended operation but enough for the outer contract to record a permanent failure, removing a recovery path for an operation that could otherwise be retried.
The technical disclosure reviewed EIP-8037 and EIP-8038 in the October 13 specification version, and its gas examples describe proposed execution behavior. The state-gas reservoir passes through calls in full, forwarding limits apply to execution gas, and gasleft() reports only the remaining execution gas. Under the reviewed rules, clearing storage slots that were zero at the start of a transaction could return up to 97,920 execution gas. An intermediary contract could also, upon REVERT, credit previously counted state-creation costs back and return them to the caller.

Interpol’s Operation Serengeti III, coordinated across 21 countries from June 29 to August 31, 2026, arrested 1,462 suspects, dismantled 10,909 malicious networks and recovered more than $105 million in illicit funds. According to ChainCatcher, investigators identified 65,929 victims and linked financial investigations to losses exceeding $385 million.
In Angola, authorities dismantled two illegal cryptocurrency mining centers and arrested nine suspects, seizing more than 2,000 mining devices and six illegal power substations. The seized power infrastructure alone was valued at more than $1 million.
In Nigeria, authorities arrested a suspect linked to large-scale phishing and business email compromise schemes that collected about 2.1 million email addresses and software credentials. A separate investigation uncovered an international investment scam promoted through messaging apps that moved more than $2.4 million in suspected criminal proceeds, most of which was laundered through cryptocurrency transactions.
Interpol cybercrime director Neal Jetton said criminal networks exploit technology to target victims across borders and at unprecedented scale. He said the operation demonstrated that international cooperation remains an effective tool for dismantling criminal networks, recovering illicit assets and protecting communities.

a16z Crypto general partner Ali Yahya said on Oct. 23 that he will leave the firm and start a company. According to PANews, Yahya said the venture is at an early stage and that his current focus is building infrastructure for an “open software ecosystem.” a16z Crypto was previously renamed a16z Frontier, with its investment scope expanded to include frontier startups.

According to Jin10, Iranian Foreign Ministry spokesperson Esmaeil Baghaei said there is no such thing as an “Iran conflict,” describing it as an illegal war of aggression launched by the United States and Israel against Iran. He said refusing to call aggression by its name was not neutrality but “moral evasion,” and questioned how people could claim to confront injustice, propose workable solutions, or make a substantive contribution to peace without identifying the aggressor and the act of aggression. Baghaei said peace could not be achieved by appeasing aggressors, legitimizing aggression, condemning victims, or sacrificing fundamental principles.

US spot Bitcoin ETFs took in $528 million of net inflows on Wednesday, October 21, according to SoSoValue. That followed $23 million on Tuesday and $526.6 million on Monday, a three-day total of $1.08 billion. The streak lifted October’s net flows to about $461 million, from roughly $615 million of outflows on October 16, and year-to-date inflows to $1.34 billion.Three Days Reverse Two Weeks of OutflowsThe inflows came after two straight weeks of withdrawals: $681 million in the week to October 9 and $228 million in the week to October 16. According to Farside Investors data, BlackRock’s iShares Bitcoin Trust (IBIT) led Wednesday with $235 million, followed by the Fidelity Wise Origin Bitcoin Fund (FBTC) with about $213 million.Bitcoin briefly rose to an intraday high of $84,777 on Wednesday before slipping back to around $82,500, according to CoinGecko.Altcoin ETFs Snap Outflow StreaksEther ETFs added $15 million, ending a five-session run of outflows.

Demand through futures or direct spot buying can also move prices.

Foresight News posted on X (formerly Twitter), citing the South China Morning Post, that HSBC will begin a phased rollout of its Hong Kong dollar stablecoin, HSBC RedCoin, on October 23. The stablecoin is initially available through PayMe and HSBC’s Hong Kong mobile banking app.
The first phase supports peer-to-peer transfers and merchant payments. Users can activate a wallet without maintaining a minimum balance or opening an additional account. HSBC expects the service to reach all PayMe users before the weekend.
HSBC plans to fully integrate RedCoin into its mobile banking app by the end of the year, allowing users to subscribe to tokenized asset products instantly. The minimum investment is HK$100.

A wallet that withdrew 3,000 ETH from a centralized exchange (CEX) in 2017 transferred the funds to another CEX after remaining dormant for about 9.5 years. According to BlockBeats On-chain Detection, the transfer was observed about 10 minutes before the report on October 22. The ETH had appreciated approximately 128-fold since the withdrawal.

The PHP Foundation has acknowledged that indecision and a shortage of resources delayed a fix for a critical security flaw first identified in 2024, calling the stalled response a "structural failure," according to Cointelegraph. Government agencies and other organizations worldwide took websites offline Wednesday as a precaution while PHP released emergency patches for two related critical vulnerabilities that could let unauthenticated attackers execute code on affected servers without logging in. PHP is a programming language widely used to power websites, web applications and content management systems. In a blog post after the patch, the foundation said its developers first spotted signs of the vulnerability in 2024 but struggled to craft a fix without disrupting the large ecosystem built on PHP. "Combined with the lack of a known path to remote code execution and the small team of core developers with the necessary deep knowledge of the engine occupied with many responsibilities, this decision process caused work on a fix to stall and restart repeatedly over months," the foundation said. "We won't pretend otherwise: the delay was a structural failure, caused by both the security team's decision process and its lack of resources." The flaw was flagged again Aug. 11 after security firm Calif and OpenAI independently reported the same underlying issue — Calif demonstrated unconditional remote code execution, making it a top security priority. The disruption stretched worldwide: the Netherlands shut its digital identity service and its National Cyber Security Center took its website offline; Finland's state IT provider Valtori disconnected public web services; France's Interior Ministry temporarily took prefecture sites offline; Germany's federal IT provider ITZBund disabled several sites, according to Reuters; and Australia's Signals Directorate confirmed cyber.gov.au was affected. Japanese Prime Minister Sanae Takaichi urged operators on X to prepare the patch as quickly as possible, saying temporarily suspending website functions could reduce risk if it couldn't be applied immediately. The Wikimedia Foundation took Toolforge and Cloud VPS offline as a precaution, knocking parts of Wikipedia offline Wednesday. In crypto, SlowMist's MistEye survey identified 793 domains with direct PHP fingerprints among 1,488 assessed, urging exchanges, DeFi platforms and wallet providers to review exposure and upgrade. Intersect, the Cardano governance organization, temporarily took its Members Area offline. Coinbase chief security officer Jeff Lunglhofer said the company found no evidence of exposed PHP instances: "Whenever we hear about vulnerabilities like this, we automatically conduct a full sweep to make sure everything is as safe as we can make it. We're also working with our third party suppliers for extra assurance." BitGo said its platform was unaffected. Binance founder and former CEO Changpeng Zhao (CZ) warned internet users Wednesday to be "extra careful" visiting any website in the next few days, as some web administrators may not be up-to-date with security patches. OpenAI released a Codex skill on GitHub to help operators check for vulnerable PHP versions and identify applicable updates. The PHP security team said it has not identified any functional exploits at the time of its public disclosure.

On Oct 23, 2026, 03:45 AM(UTC). According to Binance Market Data, BNB has crossed the 740 USDT benchmark and is now trading at 740.109985 USDT, with a narrowed narrowed 0.29% decrease in 24 hours.

Developer T4T5 used Anthropic’s Claude Opus 5.5 to recreate Satoshi Nakamoto’s Bitcoin Windows executable, matching the preserved file’s SHA-256 hash and every byte. The file, commonly called Bitcoin 0.1.0, was actually version 0.1.1, compiled on January 10, 2009, at 23:16 UTC using Windows XP and MinGW GCC 3.4.5, according to BeInCrypto. No verified copy of the January 8 launch-day executable is known to survive; the reconstruction provides a reproducible record of how the early software was built.

South Korea’s Financial Services Commission said it will study allowing cryptocurrency exchanges to participate in the security token offering (STO) market, including issues related to market conditions, investor protection, licensing integration and permits for exchanges to conduct additional business. According to ChainCatcher, Financial Services Commission Chairman Lee Eog-weon supported using existing exchanges’ technology and trading infrastructure to develop the STO market and said that infrastructure should be integrated into the token securities market.

According to CNBC, Norway's sovereign wealth fund, the world's largest, recorded a third-quarter loss of 278 billion kroner ($29.7 billion), or about $30 billion, as rising interest rates weakened returns on bonds. Norges Bank Investment Management (NBIM), which manages the $2.3 trillion fund, reported a negative 3.5% return on fixed-income investments, a key driver of the overall loss. NBIM Deputy CEO Trond Grande said in a statement that the fund's overall return was slightly negative as higher rates hurt fixed-income performance.

Longtime Cardano advocate Chris O has stepped down as a delegated representative, citing Sui’s technology and adoption and saying the Cardano Foundation and others “have not kept up.” According to BeInCrypto, he still holds ADA, but it is no longer his largest position, and he asked delegators to reassign their voting power. His move marks the second well-known Cardano voice to shift toward Sui this year, after analyst Dan Gambardello moved part of his holdings to Sui in June. Cardano founder Charles Hoskinson thanked him for his time.

Bitcoin’s network hashrate has climbed to a seven-month high, even as major publicly traded miners redirect computing capacity toward artificial intelligence, indicating that other operators may be replacing the lost power and keeping competition intense. According to Cointelegraph, BlocksBridge Consulting’s latest Miner Weekly newsletter said the seven-day average hashrate had recovered above 1 zettahash per second, or 1,000 exahashes per second, its highest level since March 3. Hashrate measures the computing power used to secure the Bitcoin network. The recovery suggests miners still operating on the network have gained little relief from competition amid the industry’s transition to AI workloads. Bitcoin mining difficulty rose 5.92% on Oct. 16, and BlocksBridge projected a further 5.16% increase at the next adjustment. If that estimate holds, difficulty will have risen roughly 11.4% over two consecutive adjustments. The consultancy said the AI migration has not provided the breathing room remaining Bitcoin miners might have expected.
BlocksBridge previously reported that publicly traded miners’ realized hashrate declined 23%, while their reported revenue from AI and high-performance computing rose 52% quarter over quarter. It estimated the displaced mining capacity represented roughly $1.5 billion in hardware. Some of that capacity may be returning to the Bitcoin network as smaller and mid-sized miners buy equipment from larger operators. BlocksBridge cited Sazmining, which advertises secondhand Antminer S21 XP machines that buyers can deploy through hosting facilities in Paraguay and Texas. For miners with access to cheaper electricity, used machines may be more economical than new equipment, allowing hardware displaced by AI conversions to continue mining Bitcoin elsewhere. However, it remains unclear how much of the equipment for sale came from publicly traded miners or how much has returned to the network. The hashrate recovery also comes as some industry observers describe rising computing power as an indirect bullish signal, reflecting continued institutional investment in publicly traded mining companies. CryptoQuant founder and CEO Ki Young Ju recently made that case on X, saying higher hashrate means stronger security and better fundamentals for Bitcoin as a store of value.

South Korea’s government and central bank are pushing to revise the Foreign Exchange Transactions Act to bring stablecoins used as payment tools under regulatory oversight. According to Odaily, the country is also drafting a Digital Asset Basic Act that would establish a licensing system for cryptocurrency exchanges and set rules for stablecoin issuance.

Dogecoin Labs launched on October 21 in partnership with the Dogecoin Foundation, bringing the MyDoge wallet, DogeOS app layer and Such App payments tool under CEO Jordan Jefferson. The company aims to build the economy needed to support the community’s long-running DOGE-to-$1 goal, according to BeInCrypto. The Foundation will retain its open-source development, advocacy and community work, while Nasdaq-listed House of Doge will move some product, engineering and commercial operations to Labs in exchange for an undisclosed equity stake.

DFINITY founder Dominic Williams has accused NEAR Intents of using DFINITY’s proprietary cryptographic technology. According to Foresight News, Williams said his investigation found that a key component of NEAR Intents uses ECDSA additive key derivation and presigning algorithms described in a DFINITY paper published in 2022.
Williams said the algorithms were developed by DFINITY for integrating the Internet Computer with Ethereum. They allow multiple computers to generate a public key and sign transactions without any single node holding the full private key, he said. Williams also alleged that NEAR hired a person dismissed by DFINITY in the summer of 2021 to lead related work and deployed the algorithms across about eight servers.
Williams said NEAR’s Chain Abstraction and Intents features rely on the technology for cross-chain asset custody and swaps. He alleged that the system is not truly decentralized and carries a backdoor risk.
He also said NEAR recently attempted on GitHub to downgrade the algorithm to a slower version. Williams said Confidential Key Derivation, released in 2025, has principles similar to DFINITY’s vetKeys technology from 2023. He said DFINITY’s work is licensed only for use with the Internet Computer, arguing that NEAR’s use raises legal issues, and added that the technology could have been shared through fair cooperation if the parties had negotiated in advance.

CryptoQuant founder and CEO Ki Young Ju described Bitcoin’s rising hashrate as an “indirect bullish signal” from institutional investors backing public miners. According to Cointelegraph, Ju said in a Thursday post on X that a higher hashrate strengthens network security and Bitcoin’s fundamentals as a store of value, adding that traditional finance institutions largely back public miners. Hashrate measures the computational power used to perform calculations on a blockchain network. CryptoQuant data showed Bitcoin’s hashrate had recovered about 45% from the summer’s lows, rising from approximately 726 exahashes per second (EH/s) in July to roughly 1,050 EH/s on Wednesday. Ju sees the recovery as an institutional endorsement of Bitcoin’s security and long-term value; rising hashrate is also generally viewed as a sign of confidence among miners. However, the global hashrate remained below its October 2025 peak of 1,305 EH/s, when Bitcoin traded above $111,000. Bitcoin was trading at roughly $81,843 as Thursday’s US equities markets opened.
Public miners have continued expanding capacity, including Nasdaq-listed NIP Group, which announced a third tranche of an on-rack asset purchase agreement on Tuesday. The deal covers about 4.47 EH/s of already-deployed Bitcoin mining hardware. After it closes, the machines are expected to immediately increase NIP Group’s Bitcoin production, with hashrate across all three tranches expected to reach 13.85 EH/s. The company currently ranks as the 16th-largest public Bitcoin miner, with 3.11 EH/s in operating hashrate, while Bitdeer ranks first at 79.9 EH/s, according to Ziven data. NIP Group shares fell 6.8% on Wednesday, closing at $6.10 and extending their decline over the past year to 86%, according to Yahoo Finance. Other major miners also lost ground as the US stock market recorded its sharpest selloff since July on Wednesday. TeraWulf, Core Scientific, Cipher Mining and IREN each fell about 12%, as higher-than-expected inflation figures pressured Bitcoin miners and AI infrastructure companies.

The Starknet Foundation said a nonbinding Snapshot vote on whether to study an independent quantum-resistant L1 path has concluded, with 93.52% of participating voting power in favor. According to Foresight News, StarkWare and the Starknet Foundation will form a joint working group and begin the research immediately, assessing technical requirements, trade-offs, and potential effects on users, developers, and the ecosystem. The group will publish its findings on the governance forum over time. The Foundation said the vote does not approve a transition of Starknet to an L1. If the research supports moving forward, a detailed proposal will be submitted for another community vote.

The Arbitrum Foundation and Robinhood Chain have opened applications for the second edition of their mentorship program, which offers a total of $100,000 in prizes. According to Foresight News, the program is for early-stage teams already building or committed to building products on Arbitrum One or Robinhood Chain, and applications close on December 6, 2026.

Kuala Lumpur High Court has ordered the government to return 497.82 Bitcoin to nine victims of an investment scam. According to ChainCatcher, Malaysian media reported that the ruling found the victims had been defrauded by Fadino Khairuman and Asyran Ismail between 2015 and 2016.
The victims deposited a total of 362.04 Bitcoin into Bitkingdom wallets after being promised daily returns of 1%. The Bitcoin was later transferred to wallets held by the two men and eventually seized by law enforcement.
The judge said the assets had been transferred through multiple transactions, but the victims had not lent the Bitcoin to the defendants; they had lost it through fraud and therefore had a legitimate claim to the seized assets. The court ordered the 497.82 Bitcoin to be distributed in proportion to each victim’s original contribution, with individual shares ranging from 0.68% to 11.7% of the total.

Binance Wallet announced on X that three days remain to join its R25 Season 2 campaign. The campaign runs until 15:59 UTC on October 26, 2026.

Promotion A requires a subscription of at least 100 USDC to qualify for a share of $150,000 in PROS Boosted APR rewards. Promotion B is a leaderboard competition offering a share of $50,000 in PROS VIP-exclusive rewards. The post says leaderboard rankings will lock in three days. It identifies the vault in its access path as R25 under Binance Wallet DeFi Protocol, with the product named Axil Prime 3M USDC Vault. The two stated reward pools are $150,000 for Promotion A and $50,000 for Promotion B, together accounting for the announced $200,000 in PROS rewards.

Bitcoin Core is changing its vulnerability disclosure policy, citing how large language models (LLMs) have made some software flaws easier to discover. According to Cointelegraph, developer Antoine Poinsot outlined the change in an email to the Bitcoin Development Mailing List on Thursday. Previously, vulnerabilities were generally kept under lengthy disclosure embargoes to give users time to upgrade before technical details became public. Poinsot said that maintaining secrecy often meant fixes could not be backported to older software versions, leaving users to wait for the next major release. With some flaws now easy to rediscover using AI, he said, delaying fixes provides little protection while holding back corrected software. “The embargo period achieves little but it delays the availability of a fixed release,” Poinsot said, adding that Bitcoin Core was updating its disclosure policy accordingly. Under the revised approach, vulnerabilities considered “easily discoverable” will be fixed as soon as possible across all maintained major versions, with security advisories published alongside the updates. The category includes flaws that can be found with minimal effort, such as through a simple LLM prompt.
Other vulnerabilities will continue to follow disclosure timelines based on severity, from critical flaws that threaten Bitcoin’s fundamental security to lower-risk issues with limited effects on individual nodes. Bitcoin Core said low-severity vulnerabilities will be disclosed two weeks after a major version containing a fix is released. Medium- and high-severity vulnerabilities will be disclosed two weeks after the last affected release reaches its “End of Life,” typically a year after the fix is released in the new major version. Critical bugs are excluded from the standard policy because they would most likely require an ad hoc process. Luke de Wolf, host of the Bitcoin Infinity Show and author of “Defending Bitcoin,” said he had disagreed with Poinsot’s security approach in the past but considered the update a good one. The policy change comes amid increased AI-assisted security research across Bitcoin software. In August, the volunteer Bitcoin Red Team reported nearly 5,000 potential issues across 390 projects, though only around a fifth had been reproduced at that point. That month, Core Lightning developers urged operators to upgrade or take their nodes offline after receiving multiple AI-generated vulnerability reports, while withholding technical details for two weeks.

Marathon Fusion says it converted mercury into “real, stable gold,” beating CERN’s record by a factor of 10. The San Francisco startup announced the result on X on October 21, according to BeInCrypto, but disclosed no production volume or experimental data. Its 2025 paper modeled output of about 2 tonnes of gold per gigawatt of thermal power annually; the gold could require 7 to 17 years of storage before sale because of radioactive isotopes. Gold was trading 5.56% below its January 1 level and down another 1.2% today.

Grayscale published a crypto asset valuation analysis ranking HYPE first in tokenholder yield and CAKE first in adjusted earnings yield. According to Foresight News, the tokenholder-yield top 10 are HYPE, LIT, CAKE, AERO, UNI, RAY, PENDLE, AAVE, JUP and CRV; the adjusted-earnings-yield top 10 are CAKE, LIT, HYPE, RAY, AAVE, JUP, SKY, UNI, AERO and PENDLE.
Grayscale said many crypto assets can be valued based on cash flows. Tokenholder yield measures staking rewards and buybacks, minus the value of new issuance, as a share of circulating market capitalization. Adjusted earnings yield measures protocol earnings relative to circulating market capitalization, minus the circulating supply inflation rate, to account for token dilution.

The Optimism Foundation and Unichain Foundation plan to introduce OP Stack native interoperability on mainnet, with Unichain and OP Mainnet forming the initial group of connected chains. According to Foresight News, the feature will validate cross-chain messages at the protocol level without relying on a separate third-party bridge validator set, and will initially support native ETH transfers between the two chains. Token support, application integrations, and additional chains may be added later.
The plan requires technical preparations and governance approval. Upgrades 20 and 21 will establish infrastructure for interoperability but will not activate cross-chain functionality; activation details will be submitted through a separate governance proposal. The initial release will not include general ERC-20 transfers, unified balances or liquidity pools across the chains, or atomic execution of arbitrary cross-chain application flows.

As of October 23, 40 newly created wallets had withdrawn a total of 9,458 BTC from Wintermute since October 1. According to BlockBeats On-chain Detection, Lookonchain monitored the withdrawals.
